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.

Congratulations to everyone in the Godot community for this awesome new
release!

What started as a 3.2.4 maintenance update for the Godot 3.2 branch finally
evolved to be a very significant release which warranted a version change,
so here we are with Godot 3.3!

It includes close to 2000 commits from over 250 contributors since the 3.2.3
release in September 2020.

Thanks to all involved, whether you contributed code, documentation, bug
reports, translations, community support or donations. You all played a role
in bringing better free and open source game development tools to the world!
