This page explains the current status of the translations in GnuCash. There is a separate introduction into Translation in general, but this page explains where you are invited to work on and where not.
See also http://lists.gnucash.org/pipermail/gnucash-devel/2009-January/024700.html but the branch names there are not any longer up to date.
Stable 2.6.x releases
We release a new version of 2.6.x every 3 months, see the Release Schedule for specifics. Releases are made from the "maint" branch of the Git repository, so if you're working from a git clone that's what you want to use for translations. The "master" branch isn't stable enough yet for translations to be worth the effort.
Again: Please work on the "maint" branch of Git for your translation work, if you retrieve the code from the repository (which is highly recommended). The git repository is active and you should immediately delete your subversion repository if you have one.
Committers: Gnucash Documentation 2.6.x Series
There is a separate maint branch for documentation.
As with the application translations all documentation translations should happen on that branch. Double check Documentation Release Process#Branching Policy.
