```
### 2.5.1
```
Fixed
- [2087](https://github.com/plotly/dash/pull/2087) Fix bug [#2086](https://github.com/plotly/dash/issues/2086) in which using id as a key within a component's id breaks the new callback context's `args_grouping` function.
- [2084](https://github.com/plotly/dash/pull/2084) In dash 2.5.0, a default viewport meta tag was added as recommended for mobile-optimized sites by [mdn](https://developer.mozilla.org/en-US/docs/Web/HTML/Viewport_meta_tag)
This feature can be disabled by providing an empty viewport meta tag. e.g. `app = Dash(meta_tags=[{"name": "viewport"}])`
- [2090](https://github.com/plotly/dash/pull/2090), [#2092](https://github.com/plotly/dash/pull/2092). Fixed bug where the `path` to the `pages_folder` was incorrect on Windows.
Removed
- [2087](https://github.com/plotly/dash/pull/2087) Removed the undocumented callback context `args_grouping_values` property which was incompatible with pattern-matching callbacks.
```
### 2.5.0
```
- 3D traces are now compatible with `no-unsafe-eval` CSP rules.
```
### 2.4.1
```
Fixed
- Fix [2045](https://github.com/plotly/dash/issues/2045) import error when using pytest but `dash[testing]` is not installed.
```
### 2.4.0
```
- `legend.groupclick`

Added
- [1729](https://github.com/plotly/dash/pull/1729) Include F#, C, and MATLAB in markdown code highlighting, for the upcoming .NET and MATLAB flavors of dash.
Dash HTML Components
Removed
- [1734](https://github.com/plotly/dash/pull/1734) Removed the following obsolete `html` elements - `<command>`, `<element>`, `<isindex>`, `<listing>`, `<multicol>`, `<nextid>`. These are obsolete and had been previously removed from the reference table.
```
### 2.3.1
```
Fixed
- [1963](https://github.com/plotly/dash/pull/1963) Fix [#1780](https://github.com/plotly/dash/issues/1780) flask shutdown deprecation warning when running dashduo threaded tests.

- Half-year directive (`%h`) for date formatting
- Several other bug fixes and performance improvements
- [Patch release 2.2.1](https://github.com/plotly/plotly.js/releases/tag/v2.2.1) containing a security fix.
Added
- [932](https://github.com/plotly/dash-core-components/pull/932) Adds a new copy to clipboard component.
- [948](https://github.com/plotly/dash-core-components/pull/948)] Adds `disabled_days` prop to `DatePickerRange` and `DatePickerSingle` components. With this prop you can specify days that should be made unselectable in the date picker, in addition to those that fall outside of the range specified by `min_date_allowed` and `max_date_allowed`.
Changed
- [972](https://github.com/plotly/dash-core-components/pull/972) Updated R package vignettes and `dash-info.yaml` to regenerate examples without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`).
Dash HTML Components
Changed
- [194](https://github.com/plotly/dash-html-components/pull/194) Updated dependencies and build process
- [190](https://github.com/plotly/dash-core-components/pull/190) Updated R package vignettes and `dash-info.yaml` to regenerate examples without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`).
Dash Table
Fixed
- [907](https://github.com/plotly/dash-table/pull/907)
- Fix a bug where pagination did not work or was not visible. [834](https://github.com/plotly/dash-table/issues/834)
- Fix a bug where if you are on a page that no longer exists after the data is updated, no data is displayed. [892](https://github.com/plotly/dash-table/issues/892)
Added
- [916](https://github.com/plotly/dash-table/pull/916)
- Added `html` option to `markdown_options` prop. This enables the use of html tags in markdown text.
- [545](https://github.com/plotly/dash-table/issues/545)
- Case insensitive filtering
- New props: `filter_options` - to control case of all filters, `columns.filter_options` - to control filter case for each column
- New operators: `i=`, `ieq`, `i>=`, `ige`, `i>`, `igt`, `i<=`, `ile`, `i<`, `ilt`, `i!=`, `ine`, `icontains` - for case-insensitive filtering, `s=`, `seq`, `s>=`, `sge`, `s>`, `sgt`, `s<=`, `sle`, `s<`, `slt`, `s!=`, `sne`, `scontains` - to force case-sensitive filtering on case-insensitive columns
Changed
- [918](https://github.com/plotly/dash-core-components/pull/918) Updated all dependencies. In particular the `highlight.js` upgrade changes code highlighting in markdown: we have long used their "github" style, this has been updated to more closely match current github styles.
- [901](https://github.com/plotly/dash-core-components/pull/901) Updated R package `dash-info.yaml` to regenerate example without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`).
```
### 2.1.0
```
- New `icicle` trace type.
- New `legendrank` trace attribute.
- Several other additions and bug fixes.
```
### 2.0.0
```
- Stop exporting d3 as `Plotly.d3`, and remove many other deep pieces of the public API. This does not affect the `dcc.Graph` component, but if you make use of `Plotly` from the global scope in some other way you may be affected.
- Drop the deprecated trace types `contourgl` and `area`, as well as legacy pre-`scatterpolar` polar attributes `bar.r`, `bar.t`, `scatter.r`, `scatter.t`, `layout.radialaxis`, `layout.angularaxis`. Use `scatterpolar`, `barpolar`, and `polar` subplots instead.
- `heatmapgl` and `pointcloud` trace types, and the `transform` attribute are deprecated, and will be removed in a future release.
- Increase CSP safety by removing function constructors. 3D plots still use function constructors, but if you place one of the non-3D bundles (including the new `strict` bundle) in your `assets` folder you will have no function constructors.
- Remove "Aa" text in legends.
- Default `hovermode` to "closest".
- Default `textposition` to "auto" in `bar` traces. If you previously used the `bar.text` attribute for hover only, you will need to explicitly set `textposition="none"`.
- Add `bar.marker.pattern`, `image.zsmooth`, and various other features and bugfixes.
```
### 1.58.3
```
Added
- [888](https://github.com/plotly/dash-core-components/pull/888) Adds a `drag_value` prop to `dcc.Slider`to be able to fire callbacks from dragging and releasing the slider.
Dash HTML Components
Fixed
- [169](https://github.com/plotly/dash-html-components/pull/169) - part of fixing dash import bug https://github.com/plotly/dash/issues/1143
Dash Table
Fixed
- [854](https://github.com/plotly/dash-table/pull/854) - part of fixing dash import bug https://github.com/plotly/dash/issues/1143
```
### 1.21.0
```
Dash and Dash Renderer
Added
- [1675](https://github.com/plotly/dash/pull/1675) Add new `Dash` constructor argument `extra_hot_reload_paths`. This allows you to re-initialize the Python code of the app when non-Python files change, if you know that these files impact the app.
Changed
- [1675](https://github.com/plotly/dash/pull/1675) Remove the constraint that `requests_pathname_prefix` ends with `routes_pathname_prefix`. When you are serving your app behind a reverse proxy that rewrites URLs that constraint needs to be violated.
- [1611](https://github.com/plotly/dash/pull/1611) and [#1685](https://github.com/plotly/dash/pull/1685) Package dash-renderer artifacts and dependencies with Dash, and source renderer resources from within Dash.
- [1567](https://github.com/plotly/dash/pull/1567) Julia component generator puts components into `src/jl` - fixes an issue on case-insensitive filesystems when the component name and module name match (modulo case) and no prefix is used. Also reduces JS/Julia clutter in the overloaded `src` directory.
Fixed
- [1664](https://github.com/plotly/dash/pull/1664) Fix [#1649](https://github.com/plotly/dash/issues/1649), makes the devtools readable with a dark theme.
- [1640](https://github.com/plotly/dash/pull/1640) Fix [#1475](https://github.com/plotly/dash/issues/1475), missing `timing_information` after certain modifications to Flask behavior
Dash Core Components
Fixed
- [963](https://github.com/plotly/dash-core-components/pull/963) Fixes [#885](https://github.com/plotly/dash-core-components/issues/885)
This applies the fix from [878](https://github.com/plotly/dash-core-components/pull/878) to the RangeSlider.
It not only fixes the bug where the tooltips were visible when slider was not, but it also reduces the lag in the
tooltip when the slider handles are moved.
Updated
- [939](https://github.com/plotly/dash-core-components/pull/939) Upgrade Plotly.js to v2.2.1. Note that this is a major version upgrade to Plotly.js, however we are not treating this as a breaking change for DCC as the majority of breaking changes in Plotly.js do not affect the Dash API. The one exception is that several trace types that have long been deprecated are removed entirely.
```
### 1.20.0
```
Dash and Dash Renderer
Changed
- [1531](https://github.com/plotly/dash/pull/1531) Update the format of the docstrings to make them easier to read in the reference pages of Dash Docs and in the console. This also addresses [#1205](https://github.com/plotly/dash/issues/1205)
- [1553](https://github.com/plotly/dash/pull/1553) Increase the z-index of the Dash error menu from 1001 to 1100 in order to make sure it appears above Bootstrap components.
Fixed
- [1546](https://github.com/plotly/dash/pull/1546) Validate callback request `outputs` vs `output` to avoid a perceived security issue.
Dash Core Components
Added
- [863](https://github.com/plotly/dash-core-components/pull/863) Adds a new `Download` component. Along with this several utility functions are added to help construct the appropriate data format:
- `dcc.send_file` - send a file from disk
- `dcc.send_data_frame` - send a `DataFrame`, using one of its writer methods
- `dcc.send_bytes` - send a bytestring or the result of a bytestring writer
- `dcc.send_string` - send a string or the result of a string writer
Changed
- [923](https://github.com/plotly/dash-core-components/pull/923)
Set `autoComplete` to off in `dcc.Dropdown`. This fixes [808](https://github.com/plotly/dash-core-components/issues/808)
Fixed
- [930](https://github.com/plotly/dash-core-components/pull/930) Fixed a bug [#867](https://github.com/plotly/dash-core-components/issues/867) with `DatePickerRange` that would sometimes shift the allowed dates by one day.
- [934](https://github.com/plotly/dash-core-components/pull/934) Fixed a bug in `EnhancedTab` component that ignored `disabled_className` property
Dash HTML Components
Fixed
- [179](https://github.com/plotly/dash-html-components/pull/179) - Fixes [#77](https://github.com/plotly/dash-html-components/issues/77) Added `allow` and `referrerPolicy` properties to `html.Iframe`
- [178](https://github.com/plotly/dash-html-components/pull/178) - Fix [#161](https://github.com/plotly/dash-html-components/issues/161) <object> `data` property, and fix [#129](https://github.com/plotly/dash-html-components/issues/129) obsolete, deprecated, and discouraged elements. No elements were removed, but comments were added to the documentation about these elements detailing their limitations.
Dash Table
Changed
- [862](https://github.com/plotly/dash-table/pull/862) - update docstrings per https://github.com/plotly/dash/issues/1205
- [878](https://github.com/plotly/dash-table/pull/878) - update build process to use Webpack 5 and other latest dependencies
```
### 1.19.0
```
Dash and Dash Renderer
Added
- [1508](https://github.com/plotly/dash/pull/1508) Fix [#1403](https://github.com/plotly/dash/issues/1403): Adds an x button
to close the error messages box.
- [1525](https://github.com/plotly/dash/pull/1525) Adds support for callbacks which have overlapping inputs and outputs. Combined with `dash.callback_context` this addresses many use cases which require circular callbacks.
Changed
- [1503](https://github.com/plotly/dash/pull/1506) Fix [#1466](https://github.com/plotly/dash/issues/1466): loosen `dash[testing]` requirements for easier integration in external projects. This PR also bumps many `dash[dev]` requirements.
Fixed
- [1530](https://github.com/plotly/dash/pull/1530) Dedent error messages more carefully.
- [1527](https://github.com/plotly/dash/issues/1527) 🐛 `get_asset_url` now pulls from an external source if `assets_external_path` is set.
- updated `_add_assets_resource` to build asset urls the same way as `get_asset_url`.
- updated doc string for `assets_external_path` Dash argument to be more clear that it will always be joined with the `assets_url_path` argument when determining the url to an external asset.
- [1493](https://github.com/plotly/dash/pull/1493) Fix [#1143](https://github.com/plotly/dash/issues/1143), a bug where having a file with one of several common names (test.py, code.py, org.py, etc) that imports a dash component package would make `import dash` fail with a cryptic error message asking whether you have a file named "dash.py"
Dash Core Components
Fixed
- [905](https://github.com/plotly/dash-core-components/pull/905) Make sure the `figure` prop of `dcc.Graph` receives updates from user interactions in the graph, by using the same `layout` object as provided in the prop rather than cloning it. Fixes [#879](https://github.com/plotly/dash-core-components/issues/879).
- [903](https://github.com/plotly/dash-core-components/pull/903) Part of fixing dash import bug https://github.com/plotly/dash/issues/1143
Updated
- [911](https://github.com/plotly/dash-core-components/pull/911), [#906](https://github.com/plotly/dash-core-components/pull/906)
```
### 1.17.0
```
Changed
- [1442](https://github.com/plotly/dash/pull/1442) Update from React 16.13.0 to 16.14.0
Fixed
- [1434](https://github.com/plotly/dash/pull/1434) Fix [#1432](https://github.com/plotly/dash/issues/1432) for Julia to import non-core component packages without possible errors.
Changed
- [1448](https://github.com/plotly/dash/pull/1448) Provide a hint in the callback error when the user forgot to make `app.callback(...)` a decorator.
```
### 1.16.3
```
Fixed
- [1426](https://github.com/plotly/dash/pull/1426) Fix a regression caused by `flask-compress==1.6.0` causing performance degradation on server requests
```
### 1.16.2
```
Fixed
- [1415](https://github.com/plotly/dash/pull/1415) Fix a regression with some layouts callbacks involving dcc.Tabs, not yet loaded dash_table.DataTable and dcc.Graph to not be called
- [1416](https://github.com/plotly/dash/pull/1416) Make callback graph more robust for complex apps and some specific props (`width` in particular) that previously caused errors.
```
### 1.16.1
```
Changed
- [1376](https://github.com/plotly/dash/pull/1376) Extends the `getTransform` logic in the renderer to handle `persistenceTransforms` for both nested and non-nested persisted props. This was used to to fix [dcc#700](https://github.com/plotly/dash-core-components/issues/700) in conjunction with [dcc#854](https://github.com/plotly/dash-core-components/pull/854) by using persistenceTransforms to strip the time part of the datetime so that datepickers can persist when defined in callbacks.
Fixed
- [1408](https://github.com/plotly/dash/pull/1408) Fixes a bug where the callback graph layout would reset whenever a callback fired, losing user-initiated layout changes ([#1402](https://github.com/plotly/dash/issues/1402)) or creating a new force layout ([#1401](https://github.com/plotly/dash/issues/1401))
```
### 1.16.0
```
Added
- [1371](https://github.com/plotly/dash/pull/1371) You can now get [CSP `script-src` hashes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src) of all added inline scripts by calling `app.csp_hashes()` (both Dash internal inline scripts, and those added with `app.clientside_callback`) .
Changed
- [1385](https://github.com/plotly/dash/pull/1385) Closes [#1350](https://github.com/plotly/dash/issues/1350) and fixes a previously undefined callback behavior when multiple elements are stacked on top of one another and their `n_clicks` props are used as inputs of the same callback. The callback will now trigger once with all the triggered `n_clicks` props changes.
- [1179](https://github.com/plotly/dash/pull/1179) New and improved callback graph in the debug menu. Now based on Cytoscape for much more interactivity, plus callback profiling including number of calls, fine-grained time information, bytes sent and received, and more. You can even add custom timing information on the server with `callback_context.record_timing(name, seconds)`
Fixed
- [1384](https://github.com/plotly/dash/pull/1384) Fixed a bug introduced by [#1180](https://github.com/plotly/dash/pull/1180) breaking use of `prevent_initial_call` as a positional arg in callback definitions
```
### 1.15.0
```
Added
- [1355](https://github.com/plotly/dash/pull/1355) Removed redundant log message and consolidated logger initialization. You can now control the log level - for example suppress informational messages from Dash with `app.logger.setLevel(logging.WARNING)`.
- [1253](https://github.com/plotly/dash/pull/1253), [#1377](https://github.com/plotly/dash/pull/1377) Added experimental `--jl-prefix` option to `dash-generate-components`, optionally generates Julia version of components and corresponding Julia package
Changed
- [1180](https://github.com/plotly/dash/pull/1180) and [#1375](https://github.com/plotly/dash/pull/1375) `Input`, `Output`, and `State` in callback definitions don't need to be in lists. You still need to provide `Output` items first, then `Input` items, then `State`, and the list form is still supported. In particular, if you want to return a single output item wrapped in a length-1 list, you should still wrap the `Output` in a list. This can be useful for procedurally-generated callbacks.
- [1368](https://github.com/plotly/dash/pull/1368) Updated pytest to v6.0.1. To avoid deprecation warnings, this also updated pytest-sugar to 0.9.4 and pytest-mock to 3.2.0. The pytest-mock update only effects python >= 3.0. Pytest-mock remains pinned at 2.0.0 for python == 2.7.
```
### 1.14.0
```
Added
- [1343](https://github.com/plotly/dash/pull/1343) Add `title` parameter to set the
document title. This is the recommended alternative to setting app.title or overriding
the index HTML.
- [1315](https://github.com/plotly/dash/pull/1315) Add `update_title` parameter to set or disable the "Updating...." document title during updates. Closes [#856](https://github.com/plotly/dash/issues/856) and [#732](https://github.com/plotly/dash/issues/732)
```
### 1.13.4
```
Fixed
- [1310](https://github.com/plotly/dash/pull/1310) Fix a regression since 1.13.0 preventing more than one loading state from being shown at a time.
```
### 1.13.2
```
Fixed
- [1305](https://github.com/plotly/dash/issues/1305)
- Fix regression that causes crash when `FLASK_ENV` is modified during app execution
- Fix regression that caused tests using `_wait_for_callbacks` to fail
```
### 1.13.0
```
Added
- [1289](https://github.com/plotly/dash/pull/1289) Supports `DASH_PROXY` env var to tell `app.run_server` to report the correct URL to view your app, when it's being proxied. Throws an error if the proxy is incompatible with the host and port you've given the server.
- [1240](https://github.com/plotly/dash/pull/1240) Adds `callback_context` to clientside callbacks (e.g. `dash_clientside.callback_context.triggered`). Supports `triggered`, `inputs`, `inputs_list`, `states`, and `states_list`, all of which closely resemble their serverside cousins.
Changed
- [1237](https://github.com/plotly/dash/pull/1237) Closes [#920](https://github.com/plotly/dash/issues/920): Converts hot reload fetch failures into a server status indicator showing whether the latest fetch succeeded or failed. Callback fetch failures still appear as errors but have a clearer message.
- [1254](https://github.com/plotly/dash/pull/1254) Modifies the callback chain implementation and improves performance for apps with a lot of components
Fixed
- [1255](https://github.com/plotly/dash/pull/1255) Hard hot reload targets only the current window, not the top - so if your app is in an iframe you will only reload the app
- [1249](https://github.com/plotly/dash/pull/1249) Fixes [#919](https://github.com/plotly/dash/issues/919) so `dash.testing` is compatible with more `pytest` plugins, particularly `pytest-flake8` and `pytest-black`.
- [1248](https://github.com/plotly/dash/pull/1248) Fixes [#1245](https://github.com/plotly/dash/issues/1245), so you can use prop persistence with components that have dict IDs, ie for pattern-matching callbacks.
- [1185](https://github.com/plotly/dash/pull/1185) Sort asset directories, same as we sort files inside those directories. This way if you need your assets loaded in a certain order, you can add prefixes to subdirectory names and enforce that order.
- [1288](https://github.com/plotly/dash/pull/1288) Closes [#1285](https://github.com/plotly/dash/issues/1285): Debug=True should work in the __main__ module.
```
### 1.12.0
```
Added
- [1228](https://github.com/plotly/dash/pull/1228) Adds control over firing callbacks on page (or layout chunk) load. Individual callbacks can have their initial calls disabled in their definition `app.callback(..., prevent_initial_call=True)` and similar for `app.clientside_callback`. The app-wide default can also be changed with `app=Dash(prevent_initial_callbacks=True)`, then individual callbacks may disable this behavior.
- [1201](https://github.com/plotly/dash/pull/1201) New attribute `app.validation_layout` allows you to create a multi-page app without `suppress_callback_exceptions=True` or layout function tricks. Set this to a component layout containing the superset of all IDs on all pages in your app.
- [1078](https://github.com/plotly/dash/pull/1078) Permit usage of arbitrary file extensions for assets within component libraries
Fixed
- [1224](https://github.com/plotly/dash/pull/1224) Fixes [#1223](https://github.com/plotly/dash/issues/1223), a very specific situation in which initial callbacks will not fire.
- [1220](https://github.com/plotly/dash/pull/1220) Fixes [#1216](https://github.com/plotly/dash/issues/1216), a set of related issues about pattern-matching callbacks with `ALL` wildcards in their `Output` which would fail if no components matched the pattern.
- [1212](https://github.com/plotly/dash/pull/1212) Fixes [#1200](https://github.com/plotly/dash/issues/1200) - prior to Dash 1.11, if none of the inputs to a callback were on the page, it was not an error. This was, and is now again, treated as though the callback raised PreventUpdate. The one exception to this is with pattern-matching callbacks, when every Input uses a multi-value wildcard (ALL or ALLSMALLER), and every Output is on the page. In that case the callback fires as usual.
- [1201](https://github.com/plotly/dash/pull/1201) Fixes [#1193](https://github.com/plotly/dash/issues/1193) - prior to Dash 1.11, you could use `flask.has_request_context() == False` inside an `app.layout` function to provide a special layout containing all IDs for validation purposes in a multi-page app. Dash 1.11 broke this when we moved most of this validation into the renderer. This change makes it work again.
```
### 1.11.0
```
Added
- [1103](https://github.com/plotly/dash/pull/1103) Pattern-matching IDs and callbacks. Component IDs can be dictionaries, and callbacks can reference patterns of components, using three different wildcards: `ALL`, `MATCH`, and `ALLSMALLER`, available from `dash.dependencies`. This lets you create components on demand, and have callbacks respond to any and all of them. To help with this, `dash.callback_context` gets three new entries: `outputs_list`, `inputs_list`, and `states_list`, which contain all the ids, properties, and except for the outputs, the property values from all matched components.
- [1103](https://github.com/plotly/dash/pull/1103) `dash.testing` option `--pause`: after opening the dash app in a test, will invoke `pdb` for live debugging of both Javascript and Python. Use with a single test case like `pytest -k cbwc001 --pause`.
Changed
- [1103](https://github.com/plotly/dash/pull/1103) Multiple changes to the callback pipeline:
- `dash.callback_context.triggered` now does NOT reflect any initial values, and DOES reflect EVERY value which has been changed either by activity in the app or as a result of a previous callback. That means that the initial call of a callback with no prerequisite callbacks will list nothing as triggering. For backward compatibility, we continue to provide a length-1 list for `triggered`, but its `id` and `property` are blank strings, and `bool(triggered)` is `False`.
- A user interaction which returns the same property value as was previously present will not trigger the component to re-render, nor trigger callbacks using that property as an input.
- Callback validation is now mostly done in the browser, rather than in Python. A few things - mostly type validation, like ensuring IDs are strings or dicts and properties are strings - are still done in Python, but most others, like ensuring outputs are unique, inputs and outputs don't overlap, and (if desired) that IDs are present in the layout, are done in the browser. This means you can define callbacks BEFORE the layout and still validate IDs to the layout; and while developing an app, most errors in callback definitions will not halt the app.
Fixed
- [1103](https://github.com/plotly/dash/pull/1103) Fixed multiple bugs with chained callbacks either not triggering, inconsistently triggering, or triggering multiple times. This includes: [#635](https://github.com/plotly/dash/issues/635), [#832](https://github.com/plotly/dash/issues/832), [#1053](https://github.com/plotly/dash/issues/1053), [#1071](https://github.com/plotly/dash/issues/1071), and [#1084](https://github.com/plotly/dash/issues/1084). Also fixed [#1105](https://github.com/plotly/dash/issues/1105): async components that aren't rendered by the page (for example in a background Tab) would block the app from executing callbacks.
```
### 1.10.0
```
Added
- [1134](https://github.com/plotly/dash/pull/1134) Allow `dash.run_server()` host and port parameters to be set with environment variables HOST & PORT, respectively
Changed
- [1145](https://github.com/plotly/dash/pull/1145) Update from React 16.8.6 to 16.13.0
Fixed
- [1142](https://github.com/plotly/dash/pull/1142) [Persistence](https://dash.plot.ly/persistence): Also persist 0, empty string etc
```
### 1.9.1
```
Added
- [1133](https://github.com/plotly/dash/pull/1133) Allow the `compress` config variable to be set with an environment variable with DASH_COMPRESS=FALSE
```
### 1.9.0
```
Fixed
- [1080](https://github.com/plotly/dash/pull/1080) Handle case where dash fails to load when used inside an iframe with a sandbox attribute that only has allow-scripts
```
### 1.8.0
```
Added
- [1073](https://github.com/plotly/dash/pull/1073) Two new functions to simplify usage handling URLs and pathnames: `app.get_relative_path` & `app.trim_relative_path`.
These functions are particularly useful for apps deployed on Dash Enterprise where the apps served under a URL prefix (the app name) which is unlike apps served on localhost:8050.
- `app.get_relative_path` returns a path with the config setting `requests_pathname_prefix` prefixed. Use `app.get_relative_path` anywhere you would provide a relative pathname, like `dcc.Link(href=app.relative_path('/page-2'))` or even as an alternative to `app.get_asset_url` with e.g. `html.Img(src=app.get_relative_path('/assets/logo.png'))`.
- `app.trim_relative_path` a path with `requests_pathname_prefix` and leading & trailing
slashes stripped from it. Use this function in callbacks that deal with `dcc.Location` `pathname`
routing.
Example usage:
python
app.layout = html.Div([
dcc.Location(id='url'),
html.Div(id='content')
])
app.callback(Output('content', 'children'), [Input('url', 'pathname')])
def display_content(path):
page_name = app.strip_relative_path(path)
if not page_name: None or ''
return html.Div([
html.Img(src=app.get_relative_path('/assets/logo.png')),
dcc.Link(href=app.get_relative_path('/page-1')),
dcc.Link(href=app.get_relative_path('/page-2')),
])
elif page_name == 'page-1':
return chapters.page_1
if page_name == "page-2":
return chapters.page_2
Changed
- [1035](https://github.com/plotly/dash/pull/1035) Simplify our build process.
- [1074](https://github.com/plotly/dash/pull/1074) Error messages when providing an incorrect property to a component have been improved: they now specify the component type, library, version, and ID (if available).
Fixed
- [1037](https://github.com/plotly/dash/pull/1037) Fix no_update test to allow copies, such as those stored and retrieved from a cache.
```
### 1.7.0
```
Added
- [967](https://github.com/plotly/dash/pull/967) Add support for defining
clientside JavaScript callbacks via inline strings.
- [1020](https://github.com/plotly/dash/pull/1020) Allow `visit_and_snapshot` API in `dash.testing.browser` to stay on the page so you can run other checks.
Changed
- [1026](https://github.com/plotly/dash/pull/1026) Better error message when you forget to wrap multiple `children` in an array, and they get passed to other props.
Fixed
- [1018](https://github.com/plotly/dash/pull/1006) Fix the `dash.testing` **stop** API with process application runner in Python2. Use `kill()` instead of `communicate()` to avoid hanging.
- [1027](https://github.com/plotly/dash/pull/1027) Fix bug with renderer callback lock never resolving with non-rendered async component using the asyncDecorator
```
### 1.6.1
```
Fixed
- [1006](https://github.com/plotly/dash/pull/1006) Fix IE11 / ES5 compatibility and validation issues
- [1006](https://github.com/plotly/dash/pull/1006) Fix bug with renderer wrapper component TreeContainer to prevent useless re-renders
- [1001](https://github.com/plotly/dash/pull/1001)
- Fix and improve the `clear_input()` API in `dash.testing`, so it's more robust handling react `input`.
- make the `percy_snapshot()` API more robust, and the timeout of `wait_for_callbacks` (if set to True) will not fail the snapshot execution, but logged as potential error.
```
### 1.6.0
```
Fixed
- [999](https://github.com/plotly/dash/pull/999) Fix fingerprint for component suites with `metadata` in version.
- [983](https://github.com/plotly/dash/pull/983) Fix the assets loading issues when dashR application runner is handling with an app defined by string chunk.
```
### 1.5.1
```
Fixed
- [987](https://github.com/plotly/dash/pull/987) Fix cache string handling for component suites with nested folders in their packages.
- [986](https://github.com/plotly/dash/pull/986) Fix a bug with evaluation of `_force_eager_loading` when application is loaded with gunicorn
```
### 1.5.0
```
Added
- [964](https://github.com/plotly/dash/pull/964) Adds support for preventing updates in clientside functions.
- Reject all updates with `throw window.dash_clientside.PreventUpdate;`
- Reject a single output by returning `window.dash_clientside.no_update`
- [899](https://github.com/plotly/dash/pull/899) Add support for async dependencies and components
- [973](https://github.com/plotly/dash/pull/973) Adds support for resource caching and adds a fallback caching mechanism through etag
Fixed
- [974](https://github.com/plotly/dash/pull/974) Fix and improve a percy snapshot behavior issue we found in dash-docs testing. It adds a flag `wait_for_callbacks` to ensure that, in the context of a dash app testing, the percy snapshot action will happen only after all callbacks get fired.
```
### 1.4.1
```
Fixed
- [969](https://github.com/plotly/dash/pull/969) Fix warnings emitted by react devtools coming from our own devtools components.
```
### 1.4.0
```
Added
- [948](https://github.com/plotly/dash/pull/948) Support setting working directory for R apps run using the `dashr` fixture, primarily useful for tests with assets. `dashr.start_server` supports a `cwd` argument to set an explicit working directory, and has smarter defaults when it's omitted: if `app` is a path to an R script, uses the directory of that path; if `app` is a string, uses the directory the test file itself is in.
- [944](https://github.com/plotly/dash/pull/944)
- Relevant `dash.testing` methods can now be called with either an element or a CSS selector: `select_dcc_dropdown`, `multiple_click`, `clear_input`, `zoom_in_graph_by_ratio`, `click_at_coord_fractions`.
- Three new `dash.testing` methods: `clear_local_storage`, `clear_session_storage`, and `clear_storage` (to clear both together)
- [937](https://github.com/plotly/dash/pull/937) `dash.testing` adds two APIs `zoom_in_graph_by_ratio` and `click_at_coord_fractions` about advanced interactions using mouse `ActionChain`
- [938](https://github.com/plotly/dash/issues/938) Add debugging traces to dash backend about serving component suites, to verify the installed packages whenever in doubt.
Fixed
- [944](https://github.com/plotly/dash/pull/944) Fix a bug with persistence being toggled on/off on an existing component.
```
### 1.3.1
```
Changed
- Bump dash-core-components version from 1.2.0 to [1.2.1](https://github.com/plotly/dash-core-components/blob/master/CHANGELOG.md#120---2019-09-19)
```
### 1.3.0
```
Added
- [923](https://github.com/plotly/dash/pull/923) Add one configuration `--percy-assets` in `pytest` to specify extra application assets path if needed.
- [918](https://github.com/plotly/dash/pull/918) Add `wait_for_element_by_id` and `visit_and_snapshot` APIs in browser, add `raw_command` option (with higher priority than the default waitress one) and optional `start_timeout` argument to handle large applications within the process runner.
- [903](https://github.com/plotly/dash/pull/903) Persistence: enable props edited by the user to persist across recreating the component or reloading the page. Components need to define three new props: `persistence`, `persisted_props`, and `persistence_type` as described in the lead comment of `src/persistence.js`. App developers then enable this behavior by, in the simplest case, setting `persistence: true` on the component. First use case is table, see [dash-table#566](https://github.com/plotly/dash-table/pull/566)
Changed
- Bump dash-table version from 4.2.0 to [4.3.0](https://github.com/plotly/dash-table/blob/master/CHANGELOG.md#430---2019-09-17)
- Bump dash-core-components version from 1.1.2 to [1.2.0](https://github.com/plotly/dash-core-components/blob/master/CHANGELOG.md#120---2019-09-17)
- Bump dash-renderer version from 1.0.1 to [1.1.0](https://github.com/plotly/dash/blob/master/dash-renderer/CHANGELOG.md#110---2019-09-17)
Fixed
- [915](https://github.com/plotly/dash/issues/915) Fix `dash-generate-components` on Windows.
- [829](https://github.com/plotly/dash/issues/829) Fix the `--remote` pytest argument which was not effective in the code, adding a new argument `--remote-url` to support the selenium grid usage in the cloud.
- [910](https://github.com/plotly/dash/pull/910) Reduce the dash-renderer packages size on **PyPI** about 55% by removing the source maps. To do more advanced debugging, the source maps needs to be generated from source code with `npm run build:local` and pip install in editable mode, i.e. `pip install -e .`
```
### 1.2.0
```
Added
- [860](https://github.com/plotly/dash/pull/860) Add a new arg `dev_tools_prune_errors` to `app.run_server` and `app.enable_dev_tools`. Default `True`, tracebacks only include user code and below. Set it `False` for the previous behavior showing all the Dash and Flask parts of the stack.
Changed
- Bump dash-table version from 4.1.0 to [4.2.0](https://github.com/plotly/dash-table/blob/master/CHANGELOG.md#420---2019-08-27)
- Bump dash-core-components version from 1.1.1 to [1.1.2](https://github.com/plotly/dash-core-components/blob/master/CHANGELOG.md#112---2019-08-27)

- Bump dash-renderer version from 1.0.0 to [1.0.1](https://github.com/plotly/dash/blob/dev/dash-renderer/CHANGELOG.md#101---2019-08-27)
Fixed
- [874](https://github.com/plotly/dash/pull/874) Clean all the binary assets in dash-renderer, add tool to build all the required bundles from fresh source code to avoid confusion of the assets and improve the release process. Fixes [#868](https://github.com/plotly/dash/pull/868) and [#734](https://github.com/plotly/dash/pull/734)

With this prop you can specify days that should be made unselectable in the date picker, in addition to those that fall outside of the range specified by `min_date_allowed` and `max_date_allowed`. Changed - [972](https://github.com/plotly/dash-core-components/pull/972) Updated R package vignettes and `dash-info.yaml` to regenerate examples without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`). Dash HTML Components Changed - [194](https://github.com/plotly/dash-html-components/pull/194) Updated dependencies and build process - [190](https://github.com/plotly/dash-core-components/pull/190) Updated R package vignettes and `dash-info.yaml` to regenerate examples without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`). Dash Table Fixed - [907](https://github.com/plotly/dash-table/pull/907) - Fix a bug where pagination did not work or was not visible. [834](https://github.com/plotly/dash-table/issues/834) - Fix a bug where if you are on a page that no longer exists after the data is updated, no data is displayed. [892](https://github.com/plotly/dash-table/issues/892) Added - [916](https://github.com/plotly/dash-table/pull/916) - Added `html` option to `markdown_options` prop. This enables the use of html tags in markdown text. - [545](https://github.com/plotly/dash-table/issues/545) - Case insensitive filtering - New props: `filter_options` - to control case of all filters, `columns.filter_options` - to control filter case for each column - New operators: `i=`, `ieq`, `i>=`, `ige`, `i>`, `igt`, `i<=`, `ile`, `i<`, `ilt`, `i!=`, `ine`, `icontains` - for case-insensitive filtering, `s=`, `seq`, `s>=`, `sge`, `s>`, `sgt`, `s<=`, `sle`, `s<`, `slt`, `s!=`, `sne`, `scontains` - to force case-sensitive filtering on case-insensitive columns Changed - [918](https://github.com/plotly/dash-core-components/pull/918) Updated all dependencies. In particular the `highlight.js` upgrade changes code highlighting in markdown: we have long used their "github" style, this has been updated to more closely match current github styles. - [901](https://github.com/plotly/dash-core-components/pull/901) Updated R package `dash-info.yaml` to regenerate example without attaching now-deprecated core component packages (`dashHtmlComponents`, `dashCoreComponents`, or `dashTable`). ``` ### 2.1.0 ``` - New `icicle` trace type. - New `legendrank` trace attribute. - Several other additions and bug fixes. ``` ### 2.0.0 ``` - Stop exporting d3 as `Plotly.d3`, and remove many other deep pieces of the public API. This does not affect the `dcc.Graph` component, but if you make use of `Plotly` from the global scope in some other way you may be affected. - Drop the deprecated trace types `contourgl` and `area`, as well as legacy pre-`scatterpolar` polar attributes `bar.r`, `bar.t`, `scatter.r`, `scatter.t`, `layout.radialaxis`, `layout.angularaxis`. Use `scatterpolar`, `barpolar`, and `polar` subplots instead. - `heatmapgl` and `pointcloud` trace types, and the `transform` attribute are deprecated, and will be removed in a future release. - Increase CSP safety by removing function constructors. 3D plots still use function constructors, but if you place one of the non-3D bundles (including the new `strict` bundle) in your `assets` folder you will have no function constructors. - Remove "Aa" text in legends. - Default `hovermode` to "closest". - Default `textposition` to "auto" in `bar` traces. If you previously used the `bar.text` attribute for hover only, you will need to explicitly set `textposition="none"`. - Add `bar.marker.pattern`, `image.zsmooth`, and various other features and bugfixes. ``` ### 1.58.3 ``` Added - [888](https://github.com/plotly/dash-core-components/pull/888) Adds a `drag_value` prop to `dcc.Slider`to be able to fire callbacks from dragging and releasing the slider. Dash HTML Components Fixed - [169](https://github.com/plotly/dash-html-components/pull/169) - part of fixing dash import bug https://github.com/plotly/dash/issues/1143 Dash Table Fixed - [854](https://github.com/plotly/dash-table/pull/854) - part of fixing dash import bug https://github.com/plotly/dash/issues/1143 ``` ### 1.21.0 ``` Dash and Dash Renderer Added - [1675](https://github.com/plotly/dash/pull/1675) Add new `Dash` constructor argument `extra_hot_reload_paths`. This allows you to re-initialize the Python code of the app when non-Python files change, if you know that these files impact the app. Changed - [1675](https://github.com/plotly/dash/pull/1675) Remove the constraint that `requests_pathname_prefix` ends with `routes_pathname_prefix`. When you are serving your app behind a reverse proxy that rewrites URLs that constraint needs to be violated. - [1611](https://github.com/plotly/dash/pull/1611) and [#1685](https://github.com/plotly/dash/pull/1685) Package dash-renderer artifacts and dependencies with Dash, and source renderer resources from within Dash. - [1567](https://github.com/plotly/dash/pull/1567) Julia component generator puts components into `src/jl` - fixes an issue on case-insensitive filesystems when the component name and module name match (modulo case) and no prefix is used. Also reduces JS/Julia clutter in the overloaded `src` directory. Fixed - [1664](https://github.com/plotly/dash/pull/1664) Fix [#1649](https://github.com/plotly/dash/issues/1649), makes the devtools readable with a dark theme. - [1640](https://github.com/plotly/dash/pull/1640) Fix [#1475](https://github.com/plotly/dash/issues/1475), missing `timing_information` after certain modifications to Flask behavior Dash Core Components Fixed - [963](https://github.com/plotly/dash-core-components/pull/963) Fixes [#885](https://github.com/plotly/dash-core-components/issues/885) This applies the fix from [878](https://github.com/plotly/dash-core-components/pull/878) to the RangeSlider. It not only fixes the bug where the tooltips were visible when slider was not, but it also reduces the lag in the tooltip when the slider handles are moved. Updated - [939](https://github.com/plotly/dash-core-components/pull/939) Upgrade Plotly.js to v2.2.1. Note that this is a major version upgrade to Plotly.js, however we are not treating this as a breaking change for DCC as the majority of breaking changes in Plotly.js do not affect the Dash API. The one exception is that several trace types that have long been deprecated are removed entirely. ``` ### 1.20.0 ``` Dash and Dash Renderer Changed - [1531](https://github.com/plotly/dash/pull/1531) Update the format of the docstrings to make them easier to read in the reference pages of Dash Docs and in the console. This also addresses [#1205](https://github.com/plotly/dash/issues/1205) - [1553](https://github.com/plotly/dash/pull/1553) Increase the z-index of the Dash error menu from 1001 to 1100 in order to make sure it appears above Bootstrap components. Fixed - [1546](https://github.com/plotly/dash/pull/1546) Validate callback request `outputs` vs `output` to avoid a perceived security issue. Dash Core Components Added - [863](https://github.com/plotly/dash-core-components/pull/863) Adds a new `Download` component. Along with this several utility functions are added to help construct the appropriate data format: - `dcc.send_file` - send a file from disk - `dcc.send_data_frame` - send a `DataFrame`, using one of its writer methods - `dcc.send_bytes` - send a bytestring or the result of a bytestring writer - `dcc.send_string` - send a string or the result of a string writer Changed - [923](https://github.com/plotly/dash-core-components/pull/923) Set `autoComplete` to off in `dcc.Dropdown`.

No elements were removed, but comments were added to the documentation about these elements detailing their limitations. Dash Table Changed - [862](https://github.com/plotly/dash-table/pull/862) - update docstrings per https://github.com/plotly/dash/issues/1205 - [878](https://github.com/plotly/dash-table/pull/878) - update build process to use Webpack 5 and other latest dependencies ``` ### 1.19.0 ``` Dash and Dash Renderer Added - [1508](https://github.com/plotly/dash/pull/1508) Fix [#1403](https://github.com/plotly/dash/issues/1403): Adds an x button to close the error messages box. - [1525](https://github.com/plotly/dash/pull/1525) Adds support for callbacks which have overlapping inputs and outputs. Combined with `dash.callback_context` this addresses many use cases which require circular callbacks. Changed - [1503](https://github.com/plotly/dash/pull/1506) Fix [#1466](https://github.com/plotly/dash/issues/1466): loosen `dash[testing]` requirements for easier integration in external projects. This PR also bumps many `dash[dev]` requirements. Fixed - [1530](https://github.com/plotly/dash/pull/1530) Dedent error messages more carefully. - [1527](https://github.com/plotly/dash/issues/1527) 🐛 `get_asset_url` now pulls from an external source if `assets_external_path` is set. - updated `_add_assets_resource` to build asset urls the same way as `get_asset_url`. - updated doc string for `assets_external_path` Dash argument to be more clear that it will always be joined with the `assets_url_path` argument when determining the url to an external asset. - [1493](https://github.com/plotly/dash/pull/1493) Fix [#1143](https://github.com/plotly/dash/issues/1143), a bug where having a file with one of several common names (test.py, code.py, org.py, etc) that imports a dash component package would make `import dash` fail with a cryptic error message asking whether you have a file named "dash.py" Dash Core Components Fixed - [905](https://github.com/plotly/dash-core-components/pull/905) Make sure the `figure` prop of `dcc.Graph` receives updates from user interactions in the graph, by using the same `layout` object as provided in the prop rather than cloning it. Fixes [#879](https://github.com/plotly/dash-core-components/issues/879). - [903](https://github.com/plotly/dash-core-components/pull/903) Part of fixing dash import bug https://github.com/plotly/dash/issues/1143 Updated - [911](https://github.com/plotly/dash-core-components/pull/911), [#906](https://github.com/plotly/dash-core-components/pull/906) ``` ### 1.17.0 ``` Changed - [1442](https://github.com/plotly/dash/pull/1442) Update from React 16.13.0 to 16.14.0 Fixed - [1434](https://github.com/plotly/dash/pull/1434) Fix [#1432](https://github.com/plotly/dash/issues/1432) for Julia to import non-core component packages without possible errors. Changed - [1448](https://github.com/plotly/dash/pull/1448) Provide a hint in the callback error when the user forgot to make `app.callback(...)` a decorator. ``` ### 1.16.3 ``` Fixed - [1426](https://github.com/plotly/dash/pull/1426) Fix a regression caused by `flask-compress==1.6.0` causing performance degradation on server requests ``` ### 1.16.2 ``` Fixed - [1415](https://github.com/plotly/dash/pull/1415) Fix a regression with some layouts callbacks involving dcc.Tabs, not yet loaded dash_table.DataTable and dcc.Graph to not be called - [1416](https://github.com/plotly/dash/pull/1416) Make callback graph more robust for complex apps and some specific props (`width` in particular) that previously caused errors. ``` ### 1.16.1 ``` Changed - [1376](https://github.com/plotly/dash/pull/1376) Extends the `getTransform` logic in the renderer to handle `persistenceTransforms` for both nested and non-nested persisted props. This was used to to fix [dcc#700](https://github.com/plotly/dash-core-components/issues/700) in conjunction with [dcc#854](https://github.com/plotly/dash-core-components/pull/854) by using persistenceTransforms to strip the time part of the datetime so that datepickers can persist when defined in callbacks. Fixed - [1408](https://github.com/plotly/dash/pull/1408) Fixes a bug where the callback graph layout would reset whenever a callback fired, losing user-initiated layout changes ([#1402](https://github.com/plotly/dash/issues/1402)) or creating a new force layout ([#1401](https://github.com/plotly/dash/issues/1401)) ``` ### 1.16.0 ``` Added - [1371](https://github.com/plotly/dash/pull/1371) You can now get [CSP `script-src` hashes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/script-src) of all added inline scripts by calling `app.csp_hashes()` (both Dash internal inline scripts, and those added with `app.clientside_callback`) . Changed - [1385](https://github.com/plotly/dash/pull/1385) Closes [#1350](https://github.com/plotly/dash/issues/1350) and fixes a previously undefined callback behavior when multiple elements are stacked on top of one another and their `n_clicks` props are used as inputs of the same callback. The callback will now trigger once with all the triggered `n_clicks` props changes. - [1179](https://github.com/plotly/dash/pull/1179) New and improved callback graph in the debug menu. Now based on Cytoscape for much more interactivity, plus callback profiling including number of calls, fine-grained time information, bytes sent and received, and more. You can even add custom timing information on the server with `callback_context.record_timing(name, seconds)` Fixed - [1384](https://github.com/plotly/dash/pull/1384) Fixed a bug introduced by [#1180](https://github.com/plotly/dash/pull/1180) breaking use of `prevent_initial_call` as a positional arg in callback definitions ``` ### 1.15.0 ``` Added - [1355](https://github.com/plotly/dash/pull/1355) Removed redundant log message and consolidated logger initialization. You can now control the log level - for example suppress informational messages from Dash with `app.logger.setLevel(logging.WARNING)`. - [1253](https://github.com/plotly/dash/pull/1253), [#1377](https://github.com/plotly/dash/pull/1377) Added experimental `--jl-prefix` option to `dash-generate-components`, optionally generates Julia version of components and corresponding Julia package Changed - [1180](https://github.com/plotly/dash/pull/1180) and [#1375](https://github.com/plotly/dash/pull/1375) `Input`, `Output`, and `State` in callback definitions don't need to be in lists. You still need to provide `Output` items first, then `Input` items, then `State`, and the list form is still supported. In particular, if you want to return a single output item wrapped in a length-1 list, you should still wrap the `Output` in a list. This can be useful for procedurally-generated callbacks. - [1368](https://github.com/plotly/dash/pull/1368) Updated pytest to v6.0.1. To avoid deprecation warnings, this also updated pytest-sugar to 0.9.4 and pytest-mock to 3.2.0. The pytest-mock update only effects python >= 3.0. Pytest-mock remains pinned at 2.0.0 for python == 2.7. ``` ### 1.14.0 ``` Added - [1343](https://github.com/plotly/dash/pull/1343) Add `title` parameter to set the document title. This is the recommended alternative to setting app.title or overriding the index HTML. - [1315](https://github.com/plotly/dash/pull/1315) Add `update_title` parameter to set or disable the "Updating...." document title during updates. Closes [#856](https://github.com/plotly/dash/issues/856) and [#732](https://github.com/plotly/dash/issues/732) ``` ### 1.13.4 ``` Fixed - [1310](https://github.com/plotly/dash/pull/1310) Fix a regression since 1.13.0 preventing more than one loading state from being shown at a time. ``` ### 1.13.2 ``` Fixed - [1305](https://github.com/plotly/dash/issues/1305) - Fix regression that causes crash when `FLASK_ENV` is modified during app execution - Fix regression that caused tests using `_wait_for_callbacks` to fail ``` ### 1.13.0 ``` Added - [1289](https://github.com/plotly/dash/pull/1289) Supports `DASH_PROXY` env var to tell `app.run_server` to report the correct URL to view your app, when it's being proxied. Throws an error if the proxy is incompatible with the host and port you've given the server. - [1240](https://github.com/plotly/dash/pull/1240) Adds `callback_context` to clientside callbacks (e.g. `dash_clientside.callback_context.triggered`). Supports `triggered`, `inputs`, `inputs_list`, `states`, and `states_list`, all of which closely resemble their serverside cousins. Changed - [1237](https://github.com/plotly/dash/pull/1237) Closes [#920](https://github.com/plotly/dash/issues/920): Converts hot reload fetch failures into a server status indicator showing whether the latest fetch succeeded or failed. Callback fetch failures still appear as errors but have a clearer message. - [1254](https://github.com/plotly/dash/pull/1254) Modifies the callback chain implementation and improves performance for apps with a lot of components Fixed - [1255](https://github.com/plotly/dash/pull/1255) Hard hot reload targets only the current window, not the top - so if your app is in an iframe you will only reload the app - [1249](https://github.com/plotly/dash/pull/1249) Fixes [#919](https://github.com/plotly/dash/issues/919) so `dash.testing` is compatible with more `pytest` plugins, particularly `pytest-flake8` and `pytest-black`. - [1248](https://github.com/plotly/dash/pull/1248) Fixes [#1245](https://github.com/plotly/dash/issues/1245), so you can use prop persistence with components that have dict IDs, ie for pattern-matching callbacks. - [1185](https://github.com/plotly/dash/pull/1185) Sort asset directories, same as we sort files inside those directories. This way if you need your assets loaded in a certain order, you can add prefixes to subdirectory names and enforce that order. - [1288](https://github.com/plotly/dash/pull/1288) Closes [#1285](https://github.com/plotly/dash/issues/1285): Debug=True should work in the __main__ module. ``` ### 1.12.0 ``` Added - [1228](https://github.com/plotly/dash/pull/1228) Adds control over firing callbacks on page (or layout chunk) load. Individual callbacks can have their initial calls disabled in their definition `app.callback(..., prevent_initial_call=True)` and similar for `app.clientside_callback`. The app-wide default can also be changed with `app=Dash(prevent_initial_callbacks=True)`, then individual callbacks may disable this behavior. - [1201](https://github.com/plotly/dash/pull/1201) New attribute `app.validation_layout` allows you to create a multi-page app without `suppress_callback_exceptions=True` or layout function tricks. Set this to a component layout containing the superset of all IDs on all pages in your app. - [1078](https://github.com/plotly/dash/pull/1078) Permit usage of arbitrary file extensions for assets within component libraries Fixed - [1224](https://github.com/plotly/dash/pull/1224) Fixes [#1223](https://github.com/plotly/dash/issues/1223), a very specific situation in which initial callbacks will not fire. - [1220](https://github.com/plotly/dash/pull/1220) Fixes [#1216](https://github.com/plotly/dash/issues/1216), a set of related issues about pattern-matching callbacks with `ALL` wildcards in their `Output` which would fail if no components matched the pattern. - [1212](https://github.com/plotly/dash/pull/1212) Fixes [#1200](https://github.com/plotly/dash/issues/1200) - prior to Dash 1.11, if none of the inputs to a callback were on the page, it was not an error. This was, and is now again, treated as though the callback raised PreventUpdate. The one exception to this is with pattern-matching callbacks, when every Input uses a multi-value wildcard (ALL or ALLSMALLER), and every Output is on the page. In that case the callback fires as usual. - [1201](https://github.com/plotly/dash/pull/1201) Fixes [#1193](https://github.com/plotly/dash/issues/1193) - prior to Dash 1.11, you could use `flask.has_request_context() == False` inside an `app.layout` function to provide a special layout containing all IDs for validation purposes in a multi-page app. Dash 1.11 broke this when we moved most of this validation into the renderer. This change makes it work again. ``` ### 1.11.0 ``` Added - [1103](https://github.com/plotly/dash/pull/1103) Pattern-matching IDs and callbacks. Component IDs can be dictionaries, and callbacks can reference patterns of components, using three different wildcards: `ALL`, `MATCH`, and `ALLSMALLER`, available from `dash.dependencies`. This lets you create components on demand, and have callbacks respond to any and all of them. To help with this, `dash.callback_context` gets three new entries: `outputs_list`, `inputs_list`, and `states_list`, which contain all the ids, properties, and except for the outputs, the property values from all matched components. - [1103](https://github.com/plotly/dash/pull/1103) `dash.testing` option `--pause`: after opening the dash app in a test, will invoke `pdb` for live debugging of both Javascript and Python. Use with a single test case like `pytest -k cbwc001 --pause`. Changed - [1103](https://github.com/plotly/dash/pull/1103) Multiple changes to the callback pipeline: - `dash.callback_context.triggered` now does NOT reflect any initial values, and DOES reflect EVERY value which has been changed either by activity in the app or as a result of a previous callback. That means that the initial call of a callback with no prerequisite callbacks will list nothing as triggering. For backward compatibility, we continue to provide a length-1 list for `triggered`, but its `id` and `property` are blank strings, and `bool(triggered)` is `False`. - A user interaction which returns the same property value as was previously present will not trigger the component to re-render, nor trigger callbacks using that property as an input. - Callback validation is now mostly done in the browser, rather than in Python. A few things - mostly type validation, like ensuring IDs are strings or dicts and properties are strings - are still done in Python, but most others, like ensuring outputs are unique, inputs and outputs don't overlap, and (if desired) that IDs are present in the layout, are done in the browser. This means you can define callbacks BEFORE the layout and still validate IDs to the layout; and while developing an app, most errors in callback definitions will not halt the app. Fixed - [1103](https://github.com/plotly/dash/pull/1103) Fixed multiple bugs with chained callbacks either not triggering, inconsistently triggering, or triggering multiple times. This includes: [#635](https://github.com/plotly/dash/issues/635), [#832](https://github.com/plotly/dash/issues/832), [#1053](https://github.com/plotly/dash/issues/1053), [#1071](https://github.com/plotly/dash/issues/1071), and [#1084](https://github.com/plotly/dash/issues/1084). Also fixed [#1105](https://github.com/plotly/dash/issues/1105): async components that aren't rendered by the page (for example in a background Tab) would block the app from executing callbacks. ``` ### 1.10.0 ``` Added - [1134](https://github.com/plotly/dash/pull/1134) Allow `dash.run_server()` host and port parameters to be set with environment variables HOST & PORT, respectively Changed - [1145](https://github.com/plotly/dash/pull/1145) Update from React 16.8.6 to 16.13.0 Fixed - [1142](https://github.com/plotly/dash/pull/1142) [Persistence](https://dash.plot.ly/persistence): Also persist 0, empty string etc ``` ### 1.9.1 ``` Added - [1133](https://github.com/plotly/dash/pull/1133) Allow the `compress` config variable to be set with an environment variable with DASH_COMPRESS=FALSE ``` ### 1.9.0 ``` Fixed - [1080](https://github.com/plotly/dash/pull/1080) Handle case where dash fails to load when used inside an iframe with a sandbox attribute that only has allow-scripts ``` ### 1.8.0 ``` Added - [1073](https://github.com/plotly/dash/pull/1073) Two new functions to simplify usage handling URLs and pathnames: `app.get_relative_path` & `app.trim_relative_path`. These functions are particularly useful for apps deployed on Dash Enterprise where the apps served under a URL prefix (the app name) which is unlike apps served on localhost:8050. - `app.get_relative_path` returns a path with the config setting `requests_pathname_prefix` prefixed. Use `app.get_relative_path` anywhere you would provide a relative pathname, like `dcc.Link(href=app.relative_path('/page-2'))` or even as an alternative to `app.get_asset_url` with e.g. `html.Img(src=app.get_relative_path('/assets/logo.png'))`. - `app.trim_relative_path` a path with `requests_pathname_prefix` and leading & trailing slashes stripped from it. Use this function in callbacks that deal with `dcc.Location` `pathname` routing. Example usage: python app.layout = html.Div([ dcc.Location(id='url'), html.Div(id='content') ]) app.callback(Output('content', 'children'), [Input('url', 'pathname')]) def display_content(path): page_name = app.strip_relative_path(path) if not page_name: None or '' return html.Div([ html.Img(src=app.get_relative_path('/assets/logo.png')), dcc.Link(href=app.get_relative_path('/page-1')), dcc.Link(href=app.get_relative_path('/page-2')), ]) elif page_name == 'page-1': return chapters.page_1 if page_name == "page-2": return chapters.page_2 Changed - [1035](https://github.com/plotly/dash/pull/1035) Simplify our build process. - [1074](https://github.com/plotly/dash/pull/1074) Error messages when providing an incorrect property to a component have been improved: they now specify the component type, library, version, and ID (if available). Fixed - [1037](https://github.com/plotly/dash/pull/1037) Fix no_update test to allow copies, such as those stored and retrieved from a cache. ``` ### 1.7.0 ``` Added - [967](https://github.com/plotly/dash/pull/967) Add support for defining clientside JavaScript callbacks via inline strings. - [1020](https://github.com/plotly/dash/pull/1020) Allow `visit_and_snapshot` API in `dash.testing.browser` to stay on the page so you can run other checks. Changed - [1026](https://github.com/plotly/dash/pull/1026) Better error message when you forget to wrap multiple `children` in an array, and they get passed to other props. Fixed - [1018](https://github.com/plotly/dash/pull/1006) Fix the `dash.testing` **stop** API with process application runner in Python2. Use `kill()` instead of `communicate()` to avoid hanging. - [1027](https://github.com/plotly/dash/pull/1027) Fix bug with renderer callback lock never resolving with non-rendered async component using the asyncDecorator ``` ### 1.6.1 ``` Fixed - [1006](https://github.com/plotly/dash/pull/1006) Fix IE11 / ES5 compatibility and validation issues - [1006](https://github.com/plotly/dash/pull/1006) Fix bug with renderer wrapper component TreeContainer to prevent useless re-renders - [1001](https://github.com/plotly/dash/pull/1001) - Fix and improve the `clear_input()` API in `dash.testing`, so it's more robust handling react `input`. - make the `percy_snapshot()` API more robust, and the timeout of `wait_for_callbacks` (if set to True) will not fail the snapshot execution, but logged as potential error. ``` ### 1.6.0 ``` Fixed - [999](https://github.com/plotly/dash/pull/999) Fix fingerprint for component suites with `metadata` in version. - [983](https://github.com/plotly/dash/pull/983) Fix the assets loading issues when dashR application runner is handling with an app defined by string chunk. ``` ### 1.5.1 ``` Fixed - [987](https://github.com/plotly/dash/pull/987) Fix cache string handling for component suites with nested folders in their packages. - [986](https://github.com/plotly/dash/pull/986) Fix a bug with evaluation of `_force_eager_loading` when application is loaded with gunicorn ``` ### 1.5.0 ``` Added - [964](https://github.com/plotly/dash/pull/964) Adds support for preventing updates in clientside functions. - Reject all updates with `throw window.dash_clientside.PreventUpdate;` - Reject a single output by returning `window.dash_clientside.no_update` - [899](https://github.com/plotly/dash/pull/899) Add support for async dependencies and components - [973](https://github.com/plotly/dash/pull/973) Adds support for resource caching and adds a fallback caching mechanism through etag Fixed - [974](https://github.com/plotly/dash/pull/974) Fix and improve a percy snapshot behavior issue we found in dash-docs testing. It adds a flag `wait_for_callbacks` to ensure that, in the context of a dash app testing, the percy snapshot action will happen only after all callbacks get fired. ``` ### 1.4.1 ``` Fixed - [969](https://github.com/plotly/dash/pull/969) Fix warnings emitted by react devtools coming from our own devtools components. ``` ### 1.4.0 ``` Added - [948](https://github.com/plotly/dash/pull/948) Support setting working directory for R apps run using the `dashr` fixture, primarily useful for tests with assets. `dashr.start_server` supports a `cwd` argument to set an explicit working directory, and has smarter defaults when it's omitted: if `app` is a path to an R script, uses the directory of that path; if `app` is a string, uses the directory the test file itself is in. - [944](https://github.com/plotly/dash/pull/944) - Relevant `dash.testing` methods can now be called with either an element or a CSS selector: `select_dcc_dropdown`, `multiple_click`, `clear_input`, `zoom_in_graph_by_ratio`, `click_at_coord_fractions`. - Three new `dash.testing` methods: `clear_local_storage`, `clear_session_storage`, and `clear_storage` (to clear both together) - [937](https://github.com/plotly/dash/pull/937) `dash.testing` adds two APIs `zoom_in_graph_by_ratio` and `click_at_coord_fractions` about advanced interactions using mouse `ActionChain` - [938](https://github.com/plotly/dash/issues/938) Add debugging traces to dash backend about serving component suites, to verify the installed packages whenever in doubt. Fixed - [944](https://github.com/plotly/dash/pull/944) Fix a bug with persistence being toggled on/off on an existing component. ``` ### 1.3.1 ``` Changed - Bump dash-core-components version from 1.2.0 to [1.2.1](https://github.com/plotly/dash-core-components/blob/master/CHANGELOG.md#120---2019-09-19) ``` ### 1.3.0 ``` Added - [923](https://github.com/plotly/dash/pull/923) Add one configuration `--percy-assets` in `pytest` to specify extra application assets path if needed. - [918](https://github.com/plotly/dash/pull/918) Add `wait_for_element_by_id` and `visit_and_snapshot` APIs in browser, add `raw_command` option (with higher priority than the default waitress one) and optional `start_timeout` argument to handle large applications within the process runner. - [903](https://github.com/plotly/dash/pull/903) Persistence: enable props edited by the user to persist across recreating the component or reloading the page. Components need to define three new props: `persistence`, `persisted_props`, and `persistence_type` as described in the lead comment of `src/persistence.js`. App developers then enable this behavior by, in the simplest case, setting `persistence: true` on the component. First use case is table, see [dash-table#566](https://github.com/plotly/dash-table/pull/566) Changed - Bump dash-table version from 4.2.0 to [4.3.0](https://github.com/plotly/dash-table/blob/master/CHANGELOG.md#430---2019-09-17) - Bump dash-core-components version from 1.1.2 to [1.2.0](https://github.com/plotly/dash-core-components/blob/master/CHANGELOG.md#120---2019-09-17) - Bump dash-renderer version from 1.0.1 to [1.1.0](https://github.com/plotly/dash/blob/master/dash-renderer/CHANGELOG.md#110---2019-09-17) Fixed - [915](https://github.com/plotly/dash/issues/915) Fix `dash-generate-components` on Windows. - [829](https://github.com/plotly/dash/issues/829) Fix the `--remote` pytest argument which was not effective in the code, adding a new argument `--remote-url` to support the selenium grid usage in the cloud. - [910](https://github.com/plotly/dash/pull/910) Reduce the dash-renderer packages size on **PyPI** about 55% by removing the source maps. To do more advanced debugging, the source maps needs to be generated from source code with `npm run build:local` and pip install in editable mode, i.e. `pip install -e .` ``` ### 1.2.0 ``` Added - [860](https://github.com/plotly/dash/pull/860) Add a new arg `dev_tools_prune_errors` to `app.run_server` and `app.enable_dev_tools`.
