We have been testing the latest 1.3 code (1.3.r1315 rc1). Several testers so far have reported positive feedback. For details about what was fixed visit the overview page.
All bugs were fairly minor and nothing serious or hard to fix had been found. The r1315 will be the basis for the full production release 1.3.0. No more betas. The same bug fixes have also been applied to 1.4 codebase. I don't like to release both 1.4 and 1.3 at the same as there is always plenty going on with a single release. So a couple of days after 1.3 is done, I will release the updated 1.4 with the latests as well.
