Because Translate is backwards compatibel with MediaWiki 1.21 and later, this Development warning is not relevant. Please use the appropriate global to suppress deprecation warnings when using Translate in development mode.

The current practice is to fix deprecation warnings.

In some rare cases that might have been delayed if keeping BC while doing that is especially difficult, but this likely isn't one of them.

• Bug 66040 has been marked as a duplicate of this bug. ***

Marking as high because the hooks will stop working at some point if we don't implement the replacements of these hooks.

Uh this one is messy. The new hooks were introduced in 1.23 (but no @since tags, nor mentioned in release notes). Also, there were some follow-ups to them which are only in 1.24. It looks like we shouldn't use these hooks until 1.24 is the minimum version.

PS: I can't find to escape stuff like @ in Phabricator to avoid special processing.

I don't think there's a way to add @since tags for hooks, and we don't usually mention hook additions in release notes. We do usually mention deprecations, but it seems there was no release note for this one :(

Yes, Thiemo discovered that the hooks weren't being fired correctly in 1.23 and fixed it in 1.24 (08fee4ce2f1bbf362c8422a3e306a905c8775094). My fault from a4aa71c6cf7eba2322139312ad8353f1c318c06f, I was originally planning to do this differently and got confused.

You can escape all syntax by wrapping the block in %%% (three percent signs). This only works for blocks, same as ```; there isn't a more granular way, it's all-or-nothing for the entire paragraph.
