13.0.0-next.12 (2021-10-05)

Breaking Changes

core

• TypeScript versions older than 4.4.2 are no longer supported. ### service-worker
• The return type of SwUpdate#activateUpdate and SwUpdate#checkForUpdate changed to Promise<boolean>.

Although unlikely, it is possible that this change will cause TypeScript type-checking to fail in some cases. If necessary, update your types to account for the new return type.

Deprecations

service-worker

• The SwUpdate#activated observable is deprecated.

The SwUpdate#activated observable only emits values as a direct response to calling SwUpdate#activateUpdate() and was only useful for determining whether the call resulted in an update or not. Now, the return value of SwUpdate#activateUpdate() can be used to determine the outcome of the operation and therefore using SwUpdate#activated does not offer any benefit.

• The SwUpdate#availalbe observable is deprecated.

The new SwUpdate#versionUpdates observable provides the same information and more. Therefore, it is possible to rebuild the same behavior as SwUpdate#availalbe using the events emitted by SwUpdate#versionUpdates and filtering for VersionReadyEvent events. As a result, the SwUpdate#availalbe observable is now redundant.
