# [v2.2.0](https://github.com/browserless/chrome/compare/v2.1.0...v2.2.0)

**Potentially Breaking**

- `ghcr.io/browserless/chrome` now runs actual Chrome and not Chromium! If you were using this tag please update to use `ghcr.io/browserless/chromium`!
  - This Chrome tag uses the new routing convention below. If you get random 404's, please add `/chrome` to the start of the route. EG, `/pdf` becomes `/chrome/pdf`.
  - Websocket connections follow a similar breakage in that the URL will go from something like `ws://localhost:3000` to `ws://localhost:3000/chrome`.
- Adds a new `ghcr.io/browserless/chromium`, and updates `ghcr.io/browserless/chrome` to use actual Chrome.
- New and current APIs now follow a routing convention of `/$BROWSER/$ACTION`. In our Chrome image, you'll see `/chrome/pdf` for the PDF route as opposed to `/pdf`.
  - To keep things backwards compatible, all our prior REST APIs still have the same path as well as the new semantic, but only in the `multi` and `chromium` tags.
  - These backwards compatible routes are ONLY available in `ghcr.io/browserless/chromium` and `ghcr.io/browserless/multi`.
- Refer to the embedded documentation site for any and all updates on API differences.

**Other Changes**

- HTTPRoutes and WebSocket routes can now have multiple paths to listen on.
- Add `clean` command to `@browserless.io/browserless` CLI.
- Adds support for `/json/list`, `/json/new`, `/json/version` and `json/protocol` APIs (Chrome and Chromium only).
  - When both Chrome and Chromium are present (in the case of the multi image), browserless opts for Chromium for these requests.
- Removes legacy `browser.json` files since browserless now generates those and caches when requested.
- Stable docker images are coming! Please be sure to see our packages page for stable tags.
- Only verify that internally managed browsers are installed when starting.
- Preliminary support for `--headless=shell`.
- More unit-tests for the Chrome /json APIs.
- Dependency updates.

- Name is now `@browserless.io/browserless` to reflect our npm package.
- NEW: SDK is now live here: https://www.npmjs.com/package/@browserless.io/browserless.

# [v2.0.0](https://github.com/browserless/chrome/compare/master...feat/browserless-2.0)

browserless 2.0.0 represents the best body of work after running browserless for over 5 years. It contains mostly the same functionality and more, and is rebuilt to be more modular and offer a NodeJS SDK. It's also much lighter and faster than prior versions and includes a lot of semantic changes.

# [v1.48.0](https://github.com/browserless/chrome/compare/v1.47.0...v1.48.0)

**Potentially Breaking**

- API calls with `html` in their payloads now use the `page.setContent` API versus a prior hack using one-time network-request interception ([example here](https://github.com/browserless/chrome/compare/v1.47.0...master#diff-67b699af1b24472604e21081d0509620d4ab3d986fcd4f8aa0b04d5ee5e4c63fL88)). Old versions of puppeteer might not work properly with this (<= 5.x.x). This effects the following APIS: `/content`, `/pdf` and `/screenshot`.

---

# 1.1.0

With 1.1.0 we offer a refined way of dealing with both downloads and uploads. Both use-cases are tightly coupled to the file-system, and can leave you scratching your head as to what's going one. For more information and detailed documentation, please refer to our doc-site at https://www.browserless.io/

## Minor Changes

- New `WORKSPACE_DIR` variable for controlling where browserless stores files and uploads.
- New `/workspace` API for doing RESTful operations on the downloads/uploads file-system.
- New `/download` API for running a puppeteer-script, and responding with the resulting downloaded file.

## Internal Changes

- Moved routes out of the browserless module and into their own file/module.
- Renamed the `browserless-web-service` module to just `browserless` for simplicity.
- Moved the `DOWNLOAD_DIR` to `WORKSPACE_DIR` since it handles both uploads and downloads.

# 1.0.0

🥁 -- Stable version 1.0 is here! While this doesn't include major functionality changes, it _does_ change how the docker builds are generated going forward. The versioning will now contain two pieces of crucial information: the version of the _browserless_ service + the version of Chrome under-the-hood. For instance `1.2.3-puppeteer-1.10.0` is browserless at `1.2.3`, exposing puppeteer at `1.10.0`.

Similar to how NodeJS itself does docker releases, we'll now provide releases in 3 distinct ways:

- An _immutable_, pinned version release: `1.0.0-puppeteer-1.11.0`
- A mutable minor version release: `1.1-puppeteer-1.12.0`
- A mutable major version release: `1-puppeteer-1.9.0`

For production deployments, we recommend using _pinned_ version releases as they won't change once released. The mutable minor/major releases will receive on-going updates whenever we do changes that are bug-fixes or feature release. Even with the best intentions it's possible that instability can be introduced with these mutable images, hence why recommend the pinned version releases.

Finally, we'll continue to ship support for the last 5 minor versions of Puppeteer + the Google Chrome (stable). Old images will remain, but newer versions of browserless won't be included.

We'll continue to keep this changelog up-to-date anytime we do docker releases.
