Hi all
our continuous integration server now follows 4.0 branch as well:
http://ci.phpmyadmin.net/job/phpMyAdmin%204.0/
The builds are currently run nightly, just let me know if more frequent builds would be needed.
Also translation server provides 4.0 branch for translations (though there are no differences yet):
https://l10n.cihar.com/projects/phpmyadmin/4-0/
For now I plan to keep 3.5 enabled in both as well, just in case we will need another release in 3.5 series.
