The Zenphoto development team has decided to migrate our repository to GitHub. We expect to finalize this with the Zenphoto 1.4.4 release. GitHub will provide us with a much better environment for Zenphoto development, including replacement of the Trac ticket system with one integrated with the repository.
Currently only the unsupported third party themes and extensions we host have already been moved to GitHub. You will notice the button below their entries on our site. This is still a work in progress so sometimes things may be changed around and not work at once until all is settled.
We will announce when our migration is finished until then still use our bugtracker and svn as always. And of course our site will not go anywhere.
