2.5 is the current stable version.

2.4, while old, still has significant numbers of installations in the
wild.  The new release was due to the security fixes.  The other bug
fixes were included in the release because, well, they were already
there in git, and it was easier to include them than not.

2.3, while ancient, got a new release for similar reasons.

They have 2.4.18 already, but no 2.5 at all?  That's interesting.

No, it does not.  2.4+CalDAV has to date only been available as beta
builds, or via git.  The last such beta build was 2.4.17-caldav-beta10;
there probably won't be an equivalent beta based on 2.4.18.  The
caldav-2.4 git branch has, however, had the recent security fixes
applied to it (but I don't know what state it is in otherwise).

So if you need CalDAV, your best bet at the moment is probably 2.5, one
way or another.

Cheers,
