First phpMyAdmin's alpha release for 3.5 is out for some time and it's best time to start translating if you want to be on time for final release.
For information about translating, check our website, in short you can translate either offline (get file from Git, translate and post it to translations tracker) or use online translation system available here:
As you can see in the summary, there is lot of new or changed strings, many of the new ones coming from advisor. I suggest you to keep these as last to translate as there is quite lot of them and it is more important to have translated rest of application. The advisor messages are placed at the end of po file.
I believe we can reach good amount of complete translations by final release with your contributions!
PS: You can expect me again to publish translations stats on this blog as we're heading to release.
