After the decision to continue feature development for the `3.x` branch
alongside the `master` branch for Godot 4.0, we released 3.3-stable in
April 2021.

6 months and 2000 commits later, Godot 3.4 is another feature-packed milestone
for Godot 3, with a ton of improvements and fixes to make it a great option
for use in production while we wait for Godot 4.0!

A big thankyou to all contributors who work tirelessly on our two parallel
development branches and made this stable 3.4 release possible.
