### [`v5.2.0`](https://togithub.com/puppeteer/puppeteer/releases/v5.2.0)
[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v5.1.0...v5.2.0)
#### Feature changes
The experimental API for registering custom query handlers is slightly changed such that one registers query handlers containing two strategies: one for querying a single element and one for querying all matching elements.
The API for custom query handlers is unchanged:
```ts
__experimental_registerCustomQueryHandler(name: string, queryHandler: QueryHandler): void;
__experimental_unregisterCustomQueryHandler(name: string): void;
__experimental_customQueryHandlers(): Map;
__experimental_clearQueryHandlers(): void;
```
but QueryHandler is now defined as:
```ts
export interface QueryHandler {
queryOne?: (element: Element | Document, selector: string) => Element | null;
queryAll?: (element: Element | Document, selector: string) => Element[] | NodeListOf;
}
```
#### Bug fixes and improvements
- The ESM build now includes file extensions in its import statements to match the ESM spec. _Note that the ESM build is still considered experimental and should not be relied on._
- The docs on running Firefox Nightly are now much clearer.
- We now vendor in common dependencies such as Mitt so they can be used more easily outside of the Node module resolution ecosystem.

[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v5.0.0...v5.1.0)
#### Highlights:
The new [`Mouse#wheel`](https://togithub.com/puppeteer/puppeteer/blob/main/docs/api.md#mousewheeloptions) API has been merged in [#6141](https://togithub.com/puppeteer/puppeteer/issues/6141). It behaves similar to other mouse commands like up or down and therefore requires a `mouse.move(x, y)` for targeting the element properly.

### [`v5.0.0`](https://togithub.com/puppeteer/puppeteer/releases/v5.0.0)
[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v4.0.1...v5.0.0)
#### Breaking changes
##### Removal of `page.emulateMedia` ([#6084](https://togithub.com/puppeteer/puppeteer/issues/6084))
This method was deprecated and is now removed from Puppeteer. Swap to `page.emulateMediaType` which behaves identically.
##### Removal of `require('puppeteer/DeviceDescriptors')` ([#6043](https://togithub.com/puppeteer/puppeteer/issues/6043))
This top level file has been removed from the Puppeteer package. The same data is exposed via `puppeteer.devices`, so swap to that:
```js
// before
const devices = require('puppeteer/DeviceDescriptors');
// after
const puppeteer = require('puppeteer');
const devices = puppeteer.devices
```
##### Removal of `require('puppeteer/Errors')` ([#6043](https://togithub.com/puppeteer/puppeteer/issues/6043))
This top level file has been removed from the Puppeteer package. The same data is exposed via `puppeteer.errors`, so swap to that:
```js
// before
const errors = require('puppeteer/Errors');
// after
const puppeteer = require('puppeteer');
const errors = puppeteer.errors
```
#### Behind the scenes
- We've continued our drive to migrate to a new documentation system using TSDoc. These docs are available in the [`new-docs`](https://togithub.com/puppeteer/puppeteer/blob/main/new-docs/puppeteer.md) directory on GitHub. These aren't ready for use just yet but we're making great progress. You can track this work in [#6118](https://togithub.com/puppeteer/puppeteer/issues/6118).
- We've continued improving our TypeScript definitions. Our tests are now migrated to TypeScript ([#5830](https://togithub.com/puppeteer/puppeteer/issues/5830)) so that we're consuming our own API. Work continues to ship built-in type definitions in a future version. You can track this work in [#6124](https://togithub.com/puppeteer/puppeteer/issues/6124).
- We've started restructuring Puppeteer to work towards being able to better support an environment agnostic Puppeteer module. You can track this work in [#6125](https://togithub.com/puppeteer/puppeteer/issues/6125).

##### Breaking change: Puppeteer no longer uses Node’s EventEmitter library
As part of our work to make Puppeteer agnostic of its environment we are removing the dependency on Node’s EventEmitter in favour of an event emitter that is not tied to Node. Under the hood we use Mitt, but we extend Mitt with additional functionality to match most of the methods that Node’s EventEmitter provides. The following methods have been removed from Puppeteer classes that extend EventEmitter:
- `eventNames()`
- `getMaxListeners()`
- `listeners(eventName)`
- `prependListener`
- `prependOnceListener`
- `setMaxListeners(n)`
- `rawListeners(eventName)`
Additionally all the static methods on the EventEmitter class are not supported:
- `listenerCount(emitter, eventName)`
- `defaultMaxListeners`
- `errorMonitor`
Node’s EventEmitter emitted a `newListener` event when a listener was added and a `removeListener` event when one was removed. These are not supported and will not be emitted.
##### New features and improvements
- Send/receive debug logs are now split out into separate channels making the logs much clearer ([#6017](https://togithub.com/puppeteer/puppeteer/issues/6017))
- You can now call `isJavaScriptEnabled()` on a Puppeteer `page` to find out if JS is enabled on the page ([#5993](https://togithub.com/puppeteer/puppeteer/issues/5993))
##### Bug fixes
- Puppeteer is now much better at killing lingering browser processes, especially when you exit a test run with `Ctrl-C` ([#6011](https://togithub.com/puppeteer/puppeteer/issues/6011))
##### Behind the scenes
- We've started work on a new documentation system that uses TSDoc to generate documentation from our source code and have been porting documentation into code accordingly.

### [`v3.3.0`](https://togithub.com/puppeteer/puppeteer/releases/v3.3.0)
[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v3.2.0...v3.3.0)
##### Highlights
- The migration from Node's EventEmitter to the Mitt library has been **reverted in this release**. We're sorry for causing unexpected issues in the 3.2.0 release. If you were unable to upgrade from 3.1.0 to 3.2.0, you will be able to upgrade straight to 3.3.0 and not have any issues.
##### Behind the scenes
- The Puppeteer `Response` class was renamed `HTTPResponse` to avoid a clash with the TS `Response` type. We don't expose this class on the main Puppeteer instance so this shouldn't affect any of your code.
- Similarly we have renamed `Worker` to `WebWorker` to avoid a clash with the TS `Worker` type.

[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v3.1.0...v3.2.0)
##### Highlights
- We now support emulating vision deficiency types within Puppeteer using `page.emulateVisionDeficiency`. You can read more about these [on the DevTools update blog post](https://developers.google.com/web/updates/2020/03/devtools#vision-deficiencies).
- We now use [Mitt](https://togithub.com/developit/mitt/) as the Event Emitter that backs many of Puppeteer's classes rather than the EventEmitter module that ships with Node. This **is potentially a breaking change if you rely on some of the less popular EventEmitter methods** as Puppeteer's [EventEmitter](https://togithub.com/puppeteer/puppeteer/blob/master/src/EventEmitter.ts) does not support the entire suite of NodeJS EventEmitter functions. We think it's unlikely anyone has relied on these; we were able to swap out the EventEmitter in Puppeteer without any unit tests needing to change.
- Puppeteer now recognises webviews as regular pages which means you can control them just like you would control a regular page.
##### Behind the scenes
- The `Request` class has been renamed to `HTTPRequest` to avoid a clash with TypeScript's `Request` type. We'll be making similar changes to `Response` and `Worker`. This is not a breaking change as Puppeteer doesn't directly expose these classes so you shouldn't be referring to them by name in your code.

### Highlights
- Puppeteer now has experimental support for custom selector engines through [`puppeteer.__experimental_registerCustomQueryHandler`](https://togithub.com/puppeteer/puppeteer/issues/5405#issuecomment-621794572) ([#5753](https://togithub.com/puppeteer/puppeteer/issues/5753)). This functionality is _so_ highly experimental it’s not even documented in the API docs — on purpose! See [this comment](https://togithub.com/puppeteer/puppeteer/issues/5405#issuecomment-621794572) for instructions on how to try it out. We are hoping to gather feedback on whether this API is useful for you, and how we could improve it. Please [let us know what you think](https://togithub.com/puppeteer/puppeteer/issues/5405)!
### Behind the scenes
- `src/` is now 100% TypeScript! This now lays a baseline to start working on improving Puppeteer docs by automatically generating them, shipping type definitions built in (for now we recommend `@types/puppeteer`).

### [`v3.0.2`](https://togithub.com/puppeteer/puppeteer/releases/v3.0.2)
[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v3.0.1...v3.0.2)
### Highlights
- `uploadFile` now throws for non-existent files ([#5733](https://togithub.com/puppeteer/puppeteer/issues/5733))
- Puppeteer currently fails to extract Chromium when installing on Node 14 (see tracking bug: [#5719](https://togithub.com/puppeteer/puppeteer/issues/5719)). We now detect if you're on Node 14 and log a helpful error ([#5732](https://togithub.com/puppeteer/puppeteer/issues/5732)).
### Behind the scenes
- Many more files have been migrated to TypeScript and we're continuing with the goal of the `src` directory being 100% TypeScript.

[Compare Source](https://togithub.com/puppeteer/puppeteer/compare/v3.0.0...v3.0.1)
### Highlights
- File uploads should be more reliable now ([#5655](https://togithub.com/puppeteer/puppeteer/issues/5655))
- The size of the final package is smaller as we explicitly list files to publish ([#5659](https://togithub.com/puppeteer/puppeteer/issues/5659)).
- The docs now include the `libgbm-dev` dependency that's needed for Linux builds ([#5667](https://togithub.com/puppeteer/puppeteer/issues/5667), [#5693](https://togithub.com/puppeteer/puppeteer/issues/5693))
### Behind the scenes
- We're continuing to migrate to TypeScript and many files within `src/` are now TypeScript files. We're working towards a 100% TS codebase which will enable us (amongst other things) to ship high-quality type definitions for TypeScript users.
