Feature work in 3.x likely won't have a big impact on stability so we can skip
the dev/alpha phases and we'll start directly with a 3.4 beta 1 build once
significant changes have been implemented.
We decided to rename the upcoming 3.2.4 release to 3.3 to better reflect that
it is a significant feature release, and not a maintenance update.
The `3.2` branch was also renamed to `3.x` and will now be the development
branch for future 3.x releases (3.3, 3.4, etc.).
