    🔋 Features

    💥 BREAKING CHANGES

    • window: The windowBoundaries observable no longer completes the result. It was only ever meant to notify of the window boundary. To get the same behavior as the old behavior, you would need to add an endWith and a skipLast(1) like so: source$.pipe(window(notifier$.pipe(endWith(true))), skipLast(1)).
    • buffer: Final buffered values will now always be emitted. To get the same behavior as the previous release, you can use endWith and skipLast(1), like so: source$.pipe(buffer(notifier$.pipe(endWith(true))), skipLast(1))
    • buffer: closingNotifier completion no longer completes the result of buffer. If that is truly a desired behavior, then you should use takeUntil. Something like: source$.pipe(buffer(notifier$), takeUntil(notifier$.pipe(ignoreElements(), endWith(true)))), where notifier$ is multicast, although there are many ways to compose this behavior.
