Taskcluster

▶ [minor] [1875](https://github.com/taskcluster/taskcluster/issues/1875)
Taskcluster UI now adds the ability to cancel a task from the Task view

▶ [minor] [1919](https://github.com/taskcluster/taskcluster/issues/1919)
Taskcluster UI now exposes an additional env var `BANNER_MESSAGE` to inform users with important messages (e.g., "Taskcluster will be down for maintenance on November 11") in the UI.

▶ [patch] [bug 1588083](http://bugzil.la/1588083)
Deployment smoketests can now be run from a `taskcluster/taskcluster-devel:v<version>` Docker image.
See the deployment documentation for details.

▶ [patch] [1857](https://github.com/taskcluster/taskcluster/issues/1857)
Errors regarding `authorizedScopes` are now formatted in Markdown, and thus more readable in error messages in the Taskcluster UI.

▶ [patch] [1895](https://github.com/taskcluster/taskcluster/issues/1895)
Taskcluster UI CLI login now uses the intersection of scopes (?scope=...) with the user's scopes to generate the set of scopes added to the client.

▶ [patch] [1892](https://github.com/taskcluster/taskcluster/issues/1892)
Taskcluster UI now adds the ability to retrigger a task from the Task view.

▶ [patch] [1879](https://github.com/taskcluster/taskcluster/issues/1879)
Taskcluster UI now allows users to copy artifact links from index browser
through the normal right-click-copy-link.

▶ [patch] [bug 1593809](http://bugzil.la/1593809)
The taskcluster-github service now correctly uses the `github.bot_username` configuration to look up the latest status for a branch.
Deployments of Taskcluster should double-check that this value is set correctly; see the [deployment docs](https://docs.taskcluster.net/docs/manual/deploying/github) for details.

▶ [patch]
The taskcluster-index service now responds with a 404 and "Indexed task not found" when a task is not found, instead of the misleading "Indexed task has expired".

▶ [patch] [bug 1593754](http://bugzil.la/1593754)
The web-server service now uses the correct Pulse namespace to listen for pulse messages. This fixes one more bug preventing task and task-group UI from dynamically updating.

▶ [MAJOR] [bug 1591591](http://bugzil.la/1591591)
The deployment Helm variable `ui.application_name` has been renamed to a top-level `applicationName`. This value is now used as context in the GitHub status and check posts to PRs and commits.

▶ [MAJOR] [bug 1590175](http://bugzil.la/1590175)
Worker pools now support instance capacity in configuration such that larger instances can handle more tasks if desired. The configuration option, `instanceCapacity` was already accepted but previously had no effect. As long as this value is set to 1 for all aws and google worker pools, this change will have no effect.

▶ [minor] [1758](https://github.com/taskcluster/taskcluster/issues/1758)
Taskcluster shell client 'signin' command can now interact with the new UI.

▶ [patch] [1842](https://github.com/taskcluster/taskcluster/issues/1842)
API documentation display is fixed.

▶ [patch] [bug 1593142](http://bugzil.la/1593142)
AWS Providers in Worker Manager now handle `RequestLimitExceeded` errors from AWS gracefully with exponential backoff

▶ [patch] [1771](https://github.com/taskcluster/taskcluster/issues/1771)
Taskcluster now properly allows a client to be saved when the "Delete on expiration" switch is changed when updating an existent client.

*This release includes additional changes that were not considered important enough to mention here; see https://github.com/taskcluster/taskcluster/tree/v22.0.0%5E/changelog for details.*

▶ [minor] [bug 1588834](http://bugzil.la/1588834)
* AWS Provider worker pools now allow specifying additional userdata beyond that generated by the provider itself.

▶ [minor] [1529](https://github.com/taskcluster/taskcluster/issues/1529)
When a third party site tries to login to the deployment, Taskcluster now attempts to auto login when there is only one login strategy configured. Previously, a user had to click on "Sign In" then click on the login strategy.

▶ [patch] [1839](https://github.com/taskcluster/taskcluster/issues/1839)
Sign-In buttons now work properly with Firefox Nightly, instead of failing with a blank tab.

▶ [patch] [1835](https://github.com/taskcluster/taskcluster/issues/1835)
Taskcluster now properly read the expires query parameter for whitelisted third-party login clients.
It was previously creating third-party login clients using the maxExpires value.
This issue was only seen with clients that are whitelisted.

▶ [patch] [1840](https://github.com/taskcluster/taskcluster/issues/1840)
The Taskcluster UI can now fire actions with type 'task' without causing a schema validation error.

▶ [patch] [1838](https://github.com/taskcluster/taskcluster/issues/1838)
The task-group and task views now update dynamically as tasks change status.

*This release includes additional changes that were not considered important enough to mention here; see https://github.com/taskcluster/taskcluster/tree/v21.3.0%5E/changelog for details.*

▶ [minor] [bug 1589449](http://bugzil.la/1589449)
* Implements remove worker functionality in Worker Manager AWS provider.
* Corrects a typo in the route of remove worker api endpoint of Worker Manager

▶ [minor] [1713](https://github.com/taskcluster/taskcluster/issues/1713)
Taskcluster now supports command-line logins via the UI. Query parameters
are `client_id` and `callback_url`.

▶ [minor] [bug 1590848](http://bugzil.la/1590848)
The JSON-e context used to render `.taskcluster.yml` in GitHub repositories now contains `taskcluster_root_url` giving the root URL.
This can be used for conditionals in the file, or to generate URLs.

▶ [patch] [bug 1545939](http://bugzil.la/1545939)
All long-runnning processes are now restarted once every 24 hours by kubernetes. This
is partially to replicate how Heroku ran the services and partially just because it
is a good idea.

*This release includes additional changes that were not considered important enough to mention here; see https://github.com/taskcluster/taskcluster/tree/v21.2.0%5E/changelog for details.*
