Fixes#74204.
The style guide says
> Always use one space around operators and after commas
The 3to4 conversion tool currently strips space in certain scenarios.
I've updated it to add space whenever it is generating new code.
In any case where it substitutes existing code, it leaves it as-is.
For example, connect(a,b,c) becomes `connect(a, callable(b, c))`, because the converter is adding new commads/parens.
However, `xform(Vector3(a,b,c))` becomes `Transform * Vector3(a,b,c)` because it uses the user's original Vector3 string whole. If the user originally had `xform(Vector3(a, b, c))`, then it becomes `Transform * Vector3(a, b, c)`.
Ideally we'd always preserve original formatting, but this seems quite difficult, so I tried to preserve it where we can, but air on the side of following the style guide whenever we're transforming code.
Default actions are no longer internal since we want to document them.
They are still hidden from the Project Setting dialog because we hid the
whole `input/` group manually.
4 years of development.
12,000 merged pull requests.
7,000 fixed issues.
1,500 individual contributors across engine and docs.
The Godot 4.0 release is by all metrics our biggest release so far.
No stone has been left unturned, all parts of the engine have been
modernized, refactored, overhauled, rewritten, redesigned.
Our work is far from done. Many areas still have significant known issues,
and will require focused work from all willing contributors to fix blocking
bugs, implement missing features, optimize for performance or compatibility,
and improve the user experience.
But Godot 4.0 marks the start of the new, modern Godot Engine, and a solid
foundation for us all to build upon. Future 4.x releases will come with a
much faster cadence, enabling us to iterate quickly on new features and
improvements to what we already provide.
To all of you who were involved in making Godot 4.0 what it is today, however
big or small your contributions were:
THANK YOU!
This was a massive undertaking, and you all participated in unique and
wonderful ways to build a free and open source game engine for everyone to
use and enjoy. You are breathtaking! <3
We couldn't hope to complete an in-depth curated changelog for such
a massive release, so we simply link to our in-depth release notes :)
Also adds back the 3.3, 3.4, and 3.5 curated changelogs. Those were
released from the 3.x branch so theoretically do not share a common
history with 4.0 (which started development after 3.2), but in practice
users will still perceive 4.0 as the natural upgrade to 3.5.
