This reflects your plans for Zile which, AFAIK, never reached a release.
Probably, therefore, this page should reflect the "old" Zile, which continues to be widely packaged (and which I continue to maintain, though I'm pleased to say that I've had no bug reports for the Vala version in nearly 3 years, and only one bugfix release in the 2.6 (Vala) series. (Debian popcon results suggest it does still have users, obviating the obvious reason for this lack of problems!)
Looking at CVS, the sensible thing to do would seem to be to revert the page (zile.html) to version 1.16, then re-apply the relevant fixes made since then (mainly updates to HTML 5 and more modern styling).
Is that OK with you?
