Main:
- It's now implemented thanks to `<mutex>`. No more platform-specific implementations.
- `BinaryMutex` (non-recursive) is added, as an alternative for special cases.
- Doesn't need allocation/deallocation anymore. It can live in the stack and be part of other classes.
- Because of that, it's methods are now `const` and the inner mutex is `mutable` so it can be easily used in `const` contexts.
- A no-op implementation is provided if `NO_THREADS` is defined. No more need to add `#ifdef NO_THREADS` just for this.
- `MutexLock` now takes a reference. At this point the cases of null `Mutex`es are rare. If you ever need that, just don't use `MutexLock`.
- Thread-safe utilities are therefore simpler now.
Misc.:
- `ScopedMutexLock` is dropped and replaced by `MutexLock`, because they were pretty much the same.
- Every case of lock, do-something, unlock is replaced by `MutexLock` (complex cases where it's not straightfoward are kept as as explicit lock and unlock).
- `ShaderRD` contained an `std::mutex`, which has been replaced by `Mutex`.
It was initially implemented in #5871 for Godot 3.0, but never really
completed or thoroughly tested for most platforms. It then stayed in
limbo and nobody seems really keen to finish it, so it's better to
remove it in 4.0, and re-add eventually (possibly with a different API)
if there's demand and an implementation confirmed working on all
platforms.
Closes#8770.
Happy new year to the wonderful Godot community!
We're starting a new decade with a well-established, non-profit, free
and open source game engine, and tons of further improvements in the
pipeline from hundreds of contributors.
Godot will keep getting better, and we're looking forward to all the
games that the community will keep developing and releasing with it.
This makes it possible to know whether the window is focused
at a given time, without having to track the focus state manually
using `NOTIFICATION_WM_FOCUS_IN` and `NOTIFICATION_WM_FOCUS_OUT`.
This partially addresses #33928.
This is an editor setting and its value can also be toggled
using an entry in the Editor toolbar. The console will still
appear briefly when starting the project manager or editor,
as it's still compiled as console application.
Does not impact exported games, which will still run without
console in release and with console in debug mode.
A project setting or export option could be added to disable
it in debug mode if there's demand for it, but that would
greatly reduce the usefulness of debug builds if Windows users
can no longer report error and crash messages.
Fixes#17889.

This allows more consistency in the manner we include core headers,
where previously there would be a mix of absolute, relative and
include path-dependent includes.
Use a Microsoft recommended way of process termination for the project
process run from the editor. This allows loaded DLLs to receive and handle
DLL_PROCESS_DETACH notification and cleanup any global state before the
process actually exits.
