Please note that with the recent decision to set up a new shared Vue component library (https://phabricator.wikimedia.org/T288980) under changed technical aspects, we're going to put WVUI in maintenance-only mode and hope to bring the best parts (including existing components) over to this new library.
We aim to ensure your started component contributions are finalized in WVUI right now and continued to be acknowledged. This will rollout with a last minor release, integral to WVUI in-production amendments at Desktop Improvements projects over last couple of weeks.

The "started component contributions" refers to rWVUIe2204a1578b3: [ProgressBar] Add new progress bar component and rWVUI0b08d121d0f8: [ToggleButton] Add new toggle button component, both of which have been merged.

Are there any other patches that need to be merged before this last release? There are 9 patches currently open at https://gerrit.wikimedia.org/r/q/project:wvui+status:open, but I expect some of them no longer apply now that we are going to switch to a new library

Also of note, the current wvui ResourceLoader module is still just a wrapper for wvui-search, see T280828: Create a temporary entry for all WVUI components. There is a patch (https://gerrit.wikimedia.org/r/c/mediawiki/core/+/699951) to switch back to using the full bundle, but until that is done the new components added in the release won't be made available.
