In header page is warning, which @KHarlan (WMF) copy from old page (2022-03-07 13:59:35). And @Pppery removed string "for now" (3:59:3). But I see, that is develop (changes in git repository) continued. Really "deployments have been suspended", or not?
Topic on Extension talk:StructuredDiscussions
Deployments to new wikis are suspended. Bug fixes for critical issues continue to be merged and are deployed via the release train.
As far as I understand it, the Extension:StructuredDiscussions (Extension:Flow) turned out because is impractical and complexity. But the extensions which I mentioned should probably not be affected.
Ok. Thank's. What replace it, please? I use MediaWiki 1.35.5 for now, but my plan is upgrade to next LTS, but first I must solve alternatives for used extensions. I not use exactly Extension:StructuredDiscussions, only Extension:Echo and Extension:WhoIsWatching.
On Wikimedia wikis, it’s replaced by Extension:DiscussionTools.
It's not usable for me, because my wiki not use VisualEditor, but I'm sure that there be someone who could use it. Thank you.
