### 2.11.0
```
- Every trace type can now be rendered in a stricter CSP environment, specifically avoiding `unsafe-eval`. Please note: the `regl`-based traces (`scattergl`, `scatterpolargl`, `parcoords`, and `splom`) are only strict in the `strict` bundle, which is NOT served by default in Dash. To use this bundle with Dash, you must either download it and put it in your `assets/` folder, or include it as an `external_script` from the CDN: https://cdn.plot.ly/plotly-strict-2.11.0.min.js. All other trace types are strict in the normal bundle.

```
Breaking
- [2450](https://github.com/plotly/dash/pull/2450) Set label style `display: block` if `inline` is false in RadioItems & Checklist components. To keep previous behavior, set `inline=True`. This is already how it was described and worked in our documentation and other places with CSS stylesheets that set the default orientation of RadioItems and Checklist options to vertical (including Dash Design Kit), but for unstyled pages it is a breaking change.
Added
- [2392](https://github.com/plotly/dash/pull/2392) Improved pages feature:
- Accept an absolute path or a `pathlib.path` for `pages_folder`, to match `assets_folder`

- [2425](https://github.com/plotly/dash/pull/2425) Add `add_log_handler=True` to Dash init, if you don't want a log stream handler at all.
- [2260](https://github.com/plotly/dash/pull/2260) Experimental support for React 18. The default is still React v16.14.0, but to use React 18 you can either set the environment variable `REACT_VERSION=18.2.0` before running your app, or inside the app call `dash._dash_renderer._set_react_version("18.2.0")`. THIS FEATURE IS EXPERIMENTAL. It has not been tested with component suites outside the Dash core, and we may add or remove available React versions in any future release.
- [2414](https://github.com/plotly/dash/pull/2414) Add `dash.Patch`for partial update Output props without transferring the previous value in a State.

- [2426](https://github.com/plotly/dash/pull/2426) Set default interval to 1 second for app.long_callback, restoring the behavior it had before v2.6.0 when we introduced `backround=True` callbacks.
Changed
- [2425](https://github.com/plotly/dash/pull/2425) Moved the logger namespace to `dash.dash`, as library logger it should be on that namespace instead of the user app.

- Patch releases [2.5.1](https://github.com/plotly/plotly.js/releases/tag/v2.5.1), [2.6.1](https://github.com/plotly/plotly.js/releases/tag/v2.6.1), [2.6.2](https://github.com/plotly/plotly.js/releases/tag/v2.6.2), [2.6.3](https://github.com/plotly/plotly.js/releases/tag/v2.6.3), [2.6.4](https://github.com/plotly/plotly.js/releases/tag/v2.6.4), [2.8.1](https://github.com/plotly/plotly.js/releases/tag/v2.8.1), [2.8.2](https://github.com/plotly/plotly.js/releases/tag/v2.8.2), and [2.8.3](https://github.com/plotly/plotly.js/releases/tag/v2.8.3) containing bugfixes.
- This PR also upgrades various other dependencies of dash renderer and component suites.
- [1745](https://github.com/plotly/dash/pull/1745):
Improve our `extras_require`: there are now five options here, each with a well-defined role:
- `dash[dev]`: for developing and building dash components.
- `dash[testing]`: for using the `pytest` plugins in the `dash.testing` module
- `dash[diskcache]`: required if you use `DiskcacheLongCallbackManager`
- `dash[celery]`: required if you use `CeleryLongCallbackManager`
- `dash[ci]`: mainly for internal use, these are additional requirements for the Dash CI tests, exposed for other component libraries to use a matching configuration.
Added
- [1883](https://github.com/plotly/dash/pull/1883) in DataTable added `page_current` to `persisted_props` as requested in [#1860](https://github.com/plotly/dash/issues/1860)
- [1763](https://github.com/plotly/dash/pull/1763):
Dash and Dash Renderer
- `Input`, `State`, and `Output` now accept components instead of ID strings and Dash `callback` will auto-generate the component's ID under-the-hood if not supplied. This allows usage like:
python
my_input = dcc.Input()
my_output = html.Div()
app.layout = html.Div([my_input, my_output])
dash.callback(Output(my_output, 'children'), Input(my_input, 'value'))
def update(value):
return f'You have entered {value}'
Or, if using Python >=3.8 you can use the `:=` walrus operator:
python
app.layout = html.Div([
my_input := dcc.Input(),
my_output := html.Div()
])
dash.callback(Output(my_output, 'children'), Input(my_input, 'value'))
def update(value):
return f'You have entered {value}'
[1894](https://github.com/plotly/dash/pull/1894) restricted this feature so auto-generated IDs are not allowed if the app uses `dash_snapshots` (a Dash Enterprise package) or if the component uses `persistence`, as this can create confusing errors. Callback definitions can still reference components in these cases, but those components must have explicit IDs.
Dash Core Components
Rearranged Keyword Arguments & Flexible Types
**`Dropdown`, `RadioItem`, and `Checklist`**
- Rearranged Keyword Arguments - `options` & `value` are now the first two keywords which means they can be supplied as positional arguments without the keyword. Supplying the keywords (`options=` and `value=`) is still supported.
- Flexible Types - `options` can be supplied in two new forms:
1. An array of `string|number|bool` where `label` and `value` are equal to the items in the list.
2. A dictionary where the keys and values set as `value` and `label` respectively.
Before:
python
dcc.Dropdown(
options=[
{'label': 'New York', 'value': 'New York'},
{'label': 'Montreal', 'value': 'Montreal'},
],
value='New York'
)
or
python
dcc.Dropdown(
options=[
{'label': 'New York', 'value': 'NYC'},
{'label': 'Montreal', 'value': 'MTL'},
],
value='New York'
)
After:
python
dcc.Dropdown(['New York', 'Montreal'], 'New York')
Or
python
dcc.Dropdown({'NYC': 'New York', 'MTL': 'Montreal'}, 'New York')
**`RangeSlider` & `Slider`**
- Rearranged Keyword Arugments - `min`, `max`, and `step` are now the first three keyword arguments which means they can be supplied as positional arguments without the keyword.
- Flexible Types
- `step` will be calculated implicitly if not given.
- `marks` will be auto generated if not given. It will use `min` and `max` and will respect `step` if supplied. Auto generated marks labels are SI unit formatted. Around 5 human-readable marks will be created.
- To remove the Slider's marks, set `marks=None`.
Before:
python
dcc.Slider(marks={1: 2, 2: 2, 3: 3})
After:
python
dcc.Slider(min=1, max=3, step=1)
Or equivalently:
python
dcc.Slider(1, 3, 1)
Step can also be omitted and the `Slider` will attempt to create a nice, human readable step with SI units and around 5 marks:
python
dcc.Slider(0, 100)
The SI units and ranges supported in `marks` are:
* `µ` - micro, 10⁻⁶
* `m` - milli, 10⁻³
* `` (none) - 10⁰
* `k` - kilo, 10³
* `M` - mega, 10⁶
* `G` - giga, 10⁹
* `T` - tera, 10¹²
* `P` - peta, 10¹⁵
* `E` - exa, 10¹⁸
_Ranges below 10µ are not supported by the Slider. This is a bug: https://github.com/plotly/dash/issues/1766_
**`DataTable`**
- Rearranged Keyword Arguments - `data` and `columns` the first twokeyword arguments which means they can be supplied as positional arguments without the keyword.
- Inferred Properties - If `columns` isn't supplied then it is extracted from the the first row in `data`
Before:
python
dash_table.DataTable(data=df.to_dict('records'), columns=[{'name': i, 'id': i} for i in df.columns])
After:
python
dash_table.DataTable(data=df.to_dict('records'))
New Component Properties
**`Checklist` & `RadioItems`**
- A new property `inline` appends `display: inline-block` to `labelStyle`.
python
dcc.Checklist(inline=True)

```
### 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

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

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)

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

- updated doc string for `assets_external_path` Dash argument to be more clear that it will allways 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

```
### 1.16.1
```
Dash and Dash-Renderer
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))
Dash-Core-Components
Fixed
- [854](https://github.com/plotly/dash-core-components/pull/854) Used `persistenceTransforms` to strip the time part of the datetime in the persited props of DatePickerSingle (date) and DatePickerRange (end_date, start_date), fixing [dcc#700](https://github.com/plotly/dash-core-components/issues/700).
Added
- [850](https://github.com/plotly/dash-core-components/pull/850) Add property `prependData` to `Graph` to support `Plotly.prependTraces`
+ refactored the existing `extendTraces` API to be a single `mergeTraces` API that can handle both `prepend` as well as `extend`.
Updated
```
### 1.16.0
```
Dash and Dash-Renderer
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
Dash-Core-Components
Updated
- [858](https://github.com/plotly/dash-core-components/pull/858)
```
### 1.15.0
```
Dash and Dash Renderer
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.
Dash Core Components
Added
- [851](https://github.com/plotly/dash-core-components/pull/851) Add support for Dash.jl Julia built components
- [840](https://github.com/plotly/dash-core-components/pull/840) Add styling properties to `dcc.Loading` component
+ `parent_className`: Add CSS class for the outermost `dcc.Loading` parent div DOM node
+ `parent_style`: Add CSS style property for the outermost `dcc.Loading` parent div DOM node
+ provides a workaround for the previous behaviour the of `className` property, which changed in [740](https://github.com/plotly/dash-core-components/pull/740). `parent_className` (or inline styles in `parent_style`) now allow CSS rules to be applied to the outermost `dcc.Loading` div, which is no longer covered by `className` on loading completion as of Dash Core Components `>= 1.9.1` (Dash `>= 1.11.0`).
Dash HTML Components
Added
- [165](https://github.com/plotly/dash-html-components/pull/165) Add support for Dash.jl Julia component generation.

- [818](https://github.com/plotly/dash-table/pull/818) Fix a regression causing copy/paste not to work when selecting a range of cells with Shift + mouse click
- [819](https://github.com/plotly/dash-table/pull/819) Fix pagination `page_current` and `page_count` fields to accommodate larger numbers
```
### 1.14.0
```

- [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)

```
### 1.13.3
```
Dash-Table
Fixed
- [798](https://github.com/plotly/dash-table/pull/798) Fix a bug where headers are not aligned with columns after an update [#797](https://github.com/plotly/dash-table/issues/797)

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

Please note: the `regl`-based traces (`scattergl`, `scatterpolargl`, `parcoords`, and `splom`) are only strict in the `strict` bundle, which is NOT served by default in Dash. To use this bundle with Dash, you must either download it and put it in your `assets/` folder, or include it as an `external_script` from the CDN: https://cdn.plot.ly/plotly-strict-2.11.0.min.js. All other trace types are strict in the normal bundle. - Patch release [2.10.1](https://github.com/plotly/plotly.js/releases/tag/v2.5.1) containing a bugfix for `mesh3d` traces. Fixed - [1915](https://github.com/plotly/dash/pull/1915) Fix bug [#1474](https://github.com/plotly/dash/issues/1474) when both dcc.Graph and go.Figure have animation, and when the second animation in Figure is executed, the Frames from the first animation are played instead of the second one. - [1953](https://github.com/plotly/dash/pull/1953) Fix bug [#1783](https://github.com/plotly/dash/issues/1783) in which a failed hot reloader blocks the UI with alerts. - [1942](https://github.com/plotly/dash/pull/1942) Fix bug [#1663](https://github.com/plotly/dash/issues/1663) preventing pie traces from sending `customdata` with `clickData` and other events. ``` ### 2.10.2 ``` Changed - Set Flask and Werkzeug version upper bound to `<2.3`. ``` ### 2.10.1 ``` Fixed - [2545](https://github.com/plotly/dash/pull/2545) Fix typescript objectOf generation. - [2548](https://github.com/plotly/dash/pull/2548) Fix component as props callback triggering other callbacks not in response, fix [#2487](https://github.com/plotly/dash/issues/2487). ``` ### 2.10.0 ``` - Support for MathJax v3 - `fillpattern` for `scatter` traces with filled area ``` ### 2.9.3 ``` Fixed - [2489](https://github.com/plotly/dash/pull/2489) Fix location change event handling when `Location` objects are removed from the layout.

This issue would occur when the app is restarted or when running with multiple `gunicorn` workers. - [2471](https://github.com/plotly/dash/pull/2471) Fix `allow_duplicate` output with clientside callback, fix [#2467](https://github.com/plotly/dash/issues/2467) - [2473](https://github.com/plotly/dash/pull/2473) Fix background callbacks with different outputs but same function, fix [#2221](https://github.com/plotly/dash/issues/2221) ``` ### 2.9.1 ``` Fixed - [2461](https://github.com/plotly/dash/pull/2461) Fix pytest plugin make report when testing not installed, fix [#2420](https://github.com/plotly/dash/issues/2420) ``` ### 2.9.0 ``` Breaking - [2450](https://github.com/plotly/dash/pull/2450) Set label style `display: block` if `inline` is false in RadioItems & Checklist components. To keep previous behavior, set `inline=True`. This is already how it was described and worked in our documentation and other places with CSS stylesheets that set the default orientation of RadioItems and Checklist options to vertical (including Dash Design Kit), but for unstyled pages it is a breaking change. Added - [2392](https://github.com/plotly/dash/pull/2392) Improved pages feature: - Accept an absolute path or a `pathlib.path` for `pages_folder`, to match `assets_folder` - Fix inferring `use_pages=True` when you supply a custom `pages_folder` - Fix for `pages_folder` that includes special characters - New test fixture `clear_pages_state` - Make imported pages act more like regular Python modules - [2068](https://github.com/plotly/dash/pull/2068) Added `refresh="callback-nav"` in `dcc.Location`. This allows for navigation without refreshing the page when url is updated in a callback. - [2417](https://github.com/plotly/dash/pull/2417) Add wait_timeout property to customize the behavior of the default wait timeout used for by wait_for_page, fix [#1595](https://github.com/plotly/dash/issues/1595) - [2417](https://github.com/plotly/dash/pull/2417) Add the element target text for wait_for_text* error message, fix [#945](https://github.com/plotly/dash/issues/945) - [2425](https://github.com/plotly/dash/pull/2425) Add `add_log_handler=True` to Dash init, if you don't want a log stream handler at all. - [2260](https://github.com/plotly/dash/pull/2260) Experimental support for React 18. The default is still React v16.14.0, but to use React 18 you can either set the environment variable `REACT_VERSION=18.2.0` before running your app, or inside the app call `dash._dash_renderer._set_react_version("18.2.0")`. THIS FEATURE IS EXPERIMENTAL. It has not been tested with component suites outside the Dash core, and we may add or remove available React versions in any future release. - [2414](https://github.com/plotly/dash/pull/2414) Add `dash.Patch`for partial update Output props without transferring the previous value in a State. - [2414](https://github.com/plotly/dash/pull/2414) Add `allow_duplicate` to `Output` arguments allowing duplicate callbacks to target the same prop.

Updated ``` ### 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 ``` - Add horizontal colorbars. - Add text data on `heatmap` and related trace types. - Control legend group title fonts. - Patch releases [2.5.1](https://github.com/plotly/plotly.js/releases/tag/v2.5.1), [2.6.1](https://github.com/plotly/plotly.js/releases/tag/v2.6.1), [2.6.2](https://github.com/plotly/plotly.js/releases/tag/v2.6.2), [2.6.3](https://github.com/plotly/plotly.js/releases/tag/v2.6.3), [2.6.4](https://github.com/plotly/plotly.js/releases/tag/v2.6.4), [2.8.1](https://github.com/plotly/plotly.js/releases/tag/v2.8.1), [2.8.2](https://github.com/plotly/plotly.js/releases/tag/v2.8.2), and [2.8.3](https://github.com/plotly/plotly.js/releases/tag/v2.8.3) containing bugfixes. - This PR also upgrades various other dependencies of dash renderer and component suites. - [1745](https://github.com/plotly/dash/pull/1745): Improve our `extras_require`: there are now five options here, each with a well-defined role: - `dash[dev]`: for developing and building dash components. - `dash[testing]`: for using the `pytest` plugins in the `dash.testing` module - `dash[diskcache]`: required if you use `DiskcacheLongCallbackManager` - `dash[celery]`: required if you use `CeleryLongCallbackManager` - `dash[ci]`: mainly for internal use, these are additional requirements for the Dash CI tests, exposed for other component libraries to use a matching configuration. Added - [1883](https://github.com/plotly/dash/pull/1883) in DataTable added `page_current` to `persisted_props` as requested in [#1860](https://github.com/plotly/dash/issues/1860) - [1763](https://github.com/plotly/dash/pull/1763): Dash and Dash Renderer - `Input`, `State`, and `Output` now accept components instead of ID strings and Dash `callback` will auto-generate the component's ID under-the-hood if not supplied. This allows usage like: python my_input = dcc.Input() my_output = html.Div() app.layout = html.Div([my_input, my_output]) dash.callback(Output(my_output, 'children'), Input(my_input, 'value')) def update(value): return f'You have entered {value}' Or, if using Python >=3.8 you can use the `:=` walrus operator: python app.layout = html.Div([ my_input := dcc.Input(), my_output := html.Div() ]) dash.callback(Output(my_output, 'children'), Input(my_input, 'value')) def update(value): return f'You have entered {value}' [1894](https://github.com/plotly/dash/pull/1894) restricted this feature so auto-generated IDs are not allowed if the app uses `dash_snapshots` (a Dash Enterprise package) or if the component uses `persistence`, as this can create confusing errors. Callback definitions can still reference components in these cases, but those components must have explicit IDs. Dash Core Components Rearranged Keyword Arguments & Flexible Types **`Dropdown`, `RadioItem`, and `Checklist`** - Rearranged Keyword Arguments - `options` & `value` are now the first two keywords which means they can be supplied as positional arguments without the keyword. Supplying the keywords (`options=` and `value=`) is still supported. - Flexible Types - `options` can be supplied in two new forms: 1. An array of `string|number|bool` where `label` and `value` are equal to the items in the list. 2. A dictionary where the keys and values set as `value` and `label` respectively. Before: python dcc.Dropdown( options=[ {'label': 'New York', 'value': 'New York'}, {'label': 'Montreal', 'value': 'Montreal'}, ], value='New York' ) or python dcc.Dropdown( options=[ {'label': 'New York', 'value': 'NYC'}, {'label': 'Montreal', 'value': 'MTL'}, ], value='New York' ) After: python dcc.Dropdown(['New York', 'Montreal'], 'New York') Or python dcc.Dropdown({'NYC': 'New York', 'MTL': 'Montreal'}, 'New York') **`RangeSlider` & `Slider`** - Rearranged Keyword Arugments - `min`, `max`, and `step` are now the first three keyword arguments which means they can be supplied as positional arguments without the keyword. - Flexible Types - `step` will be calculated implicitly if not given. - `marks` will be auto generated if not given. It will use `min` and `max` and will respect `step` if supplied. Auto generated marks labels are SI unit formatted. Around 5 human-readable marks will be created. - To remove the Slider's marks, set `marks=None`. Before: python dcc.Slider(marks={1: 2, 2: 2, 3: 3}) After: python dcc.Slider(min=1, max=3, step=1) Or equivalently: python dcc.Slider(1, 3, 1) Step can also be omitted and the `Slider` will attempt to create a nice, human readable step with SI units and around 5 marks: python dcc.Slider(0, 100) The SI units and ranges supported in `marks` are: * `µ` - micro, 10⁻⁶ * `m` - milli, 10⁻³ * `` (none) - 10⁰ * `k` - kilo, 10³ * `M` - mega, 10⁶ * `G` - giga, 10⁹ * `T` - tera, 10¹² * `P` - peta, 10¹⁵ * `E` - exa, 10¹⁸ _Ranges below 10µ are not supported by the Slider. This is a bug: https://github.com/plotly/dash/issues/1766_ **`DataTable`** - Rearranged Keyword Arguments - `data` and `columns` the first twokeyword arguments which means they can be supplied as positional arguments without the keyword. - Inferred Properties - If `columns` isn't supplied then it is extracted from the the first row in `data` Before: python dash_table.DataTable(data=df.to_dict('records'), columns=[{'name': i, 'id': i} for i in df.columns]) After: python dash_table.DataTable(data=df.to_dict('records')) New Component Properties **`Checklist` & `RadioItems`** - A new property `inline` appends `display: inline-block` to `labelStyle`. python dcc.Checklist(inline=True) Fixed - [1879](https://github.com/plotly/dash/pull/1879) Delete redundancy in pattern-matching callback implementation, specifically when `ALL` and `MATCH` wildcards are used together. This patch was submitted by an anonymous Dash Enterprise customer. Many thanks! - [1858](https://github.com/plotly/dash/pull/1858) Support `mini-css-extract-plugin` Webpack plugin with `plotly/webpack-dash-dynamic-import` node package - used by components to support dash async chunks. Updated dependencies of other `plotly` node packages. - [1836](https://github.com/plotly/dash/pull/1836) Fix `__all__` in dcc and table for extras: dcc download helpers and table format helpers. This also restores this functionality to the obsolete top-level packages `dash_core_components` and `dash_table`. - [1822](https://github.com/plotly/dash/pull/1822) Remove Radium from renderer dependencies, as part of investigating React 17 support. - [1779](https://github.com/plotly/dash/pull/1779): - Clean up our handling of serialization problems, including fixing `orjson` for Python 3.6 - Added the ability for `dash.testing` `percy_snapshot` methods to choose widths to generate. - [1778](https://github.com/plotly/dash/pull/1778) DataTable: Fix React warnings stating that each child in a list should have a unique "key" prop - [1895](https://github.com/plotly/dash/pull/1895) Support debug=True if native namespace-packages are present ``` ### 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` - `bbox` of hover items in event data, to support custom dash-driven hover effects - Patch releases [2.3.1](https://github.com/plotly/plotly.js/releases/tag/v2.3.1), [2.4.1](https://github.com/plotly/plotly.js/releases/tag/v2.4.1), and [2.4.2](https://github.com/plotly/plotly.js/releases/tag/v2.4.2) containing various bug fixes. - [1735](https://github.com/plotly/dash/pull/1735) New `dcc.Tooltip` component. This is particularly useful for rich hover information on `dcc.Graph` charts, using the `bbox` information included in the event data in plotly.js v2.4.0 Dash Table 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. - [1995](https://github.com/plotly/dash/pull/1995) Fix [#1992](https://github.com/plotly/dash/issues/1992) ImportError: cannot import name 'get_current_traceback' from 'werkzeug.debug.tbtools'. ``` ### 2.3.0 ``` - More number formatting options due to `d3-format` upgrade. - Many new `geo` projections. - Improved rendering and performance of `scattergl`, `splom` and `parcoords` traces. ``` ### 2.2.0 ``` - Legend group titles - 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-Core-Components Added - [871](https://github.com/plotly/dash-core-components/pull/871) Add Julia syntax highlighting support for dcc.Markdown Fixed - [878](https://github.com/plotly/dash-core-components/pull/878) - Fixed [751](https://github.com/plotly/dash-core-components/issues/751), a bug that causes `dcc.Slider` and `dcc.RangerSlider` tooltips to be visible even if the slider component isn't visible (e.g. overflow), Updated - [875](https://github.com/plotly/dash-core-components/pull/875) ``` ### 1.16.3 ``` Dash and Dash-Renderer 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 ``` Dash and Dash-Renderer 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 ``` Dash and Dash-Renderer 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)) Dash-Core-Components Fixed - [854](https://github.com/plotly/dash-core-components/pull/854) Used `persistenceTransforms` to strip the time part of the datetime in the persited props of DatePickerSingle (date) and DatePickerRange (end_date, start_date), fixing [dcc#700](https://github.com/plotly/dash-core-components/issues/700). Added - [850](https://github.com/plotly/dash-core-components/pull/850) Add property `prependData` to `Graph` to support `Plotly.prependTraces` + refactored the existing `extendTraces` API to be a single `mergeTraces` API that can handle both `prepend` as well as `extend`. Updated ``` ### 1.16.0 ``` Dash and Dash-Renderer 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 Dash-Core-Components Updated - [858](https://github.com/plotly/dash-core-components/pull/858) ``` ### 1.15.0 ``` Dash and Dash Renderer Added - [1355](https://github.com/plotly/dash/pull/1355) Removed redundant log message and consolidated logger initialization.

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.

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
