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
- Mark WVUI (packages 'wvui' and 'wvui-search') as deprecated and unmaintained. Stop doing releases, even for bug fixes.
After that, we would migrate non-production code from WVUI to Codex, and remove Codex from MW core, which is captured in T310244: Remove WVUI from MediaWiki core.
All of these are also blocked on T302772: Application Security Review Request : Codex, as we can't use Codex in any production code until its security review is completed.
Related, but not a blocker, is T286835: Port RelatedArticles to Codex. 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).
