Differences between 6.02 and 6.04?

Hello, the versions 6.02/10 6.04/00 have been released on June, 2. What are the differences between these 2 versions? Is it planned to support 3 differents branches (5.34, 6.02 and 6.04)?
Thanks in advance for the explanations.

6.02 is a “bug fixes only” version now. The new developments (cf new palettes for instance) went in 6.04.
