WVUI is currently in maintenance mode, see T290051. This means no new features are added, but changes are still made and new releases done when necessary to fix bugs. This still happens sometimes, because there is still code using WVUI.
We would like to deprecate WVUI, migrate all code that uses it to Codex, and then remove WVUI completely.
[ ] Migrate production code from WVUI to Codex
[ ] {T303558}
[ ] {T310241}
[ ] Mark WVUI as deprecated and unmaintained. Stop doing releases, even for bug fixes.
[ ] Migrate non-production code from WVUI to Codex
[ ] {T300595} (extension is not currently deployed in production, only on beta labs; production deployment is blocked on porting to Codex)
[ ] {T310240} (extension is deployed in production, but WVUI code is behind a disabled feature flag)
[ ] {T310244}
All of these are also blocked on {T302772}, as we can't use Codex in any production code until its security review is completed.
Related, but not a blocker, is {T286835}. There is a patch to port RelatedArticles to WVUI, but it was never merged. There is now an alternative patch to port RelatedArticles to Codex instead of WVUI. That patch can be merged once the other issues on T286835 are addressed (and once the security review is done).
