    • Add pybind11/gil_safe_call_once.h (to fix deadlocks in pybind11/numpy.h) (#4877) · 0e2c3e5d 
      * LazyInitializeAtLeastOnceDestroyNever v1

* Go back to using `union` as originally suggested by jbms@. The trick (also suggested by jbms@) is to add empty ctor + dtor.

* Add Default Member Initializer on `value_storage_` as suggested by @tkoeppe:

https://github.com/pybind/pybind11/pull/4877#issuecomment-1753201342

This fixes the errors reported under commit f07b28bda9f91fb723aa898a21c81b6dd6857072.

* Move PYBIND11_CONSTINIT to detail/common.h

* Move code to the right places, rename new class and some variables.

* Fix oversight: update tests/extra_python_package/test_files.py

* Get the name right first.

* Use `std::call_once`, `std::atomic`, following a pattern developed by @tkoeppe

* Make the API more self-documenting (and possibly more easily reusable).

* google-clang-tidy IWYU fixes

* Rewrite comment as suggested by @tkoeppe

* Update test_exceptions.cpp and exceptions.rst

* Fix oversight in previous commit: add `PYBIND11_CONSTINIT`

As suggested by @tkoeppe: not seeing any reasonable use in which `get_stored` has to be const.

* Add `assert(PyGILState_Check())` in `gil_scoped_release` ctor (simple & non-simple implementation) as suggested by @EthanSteinberg.

* Fix oversight in previous commit (missing include cassert).

* Remove use of std::atomic, leaving comments with rationale, why it is not needed.

* Rewrite comment re `std:optional` based on deeper reflection (aka 2nd thoughts).

* Additional comment with the conclusion of a discussion under PR #4877.

* https://github.com/pybind/pybind11/pull/4877#issuecomment-1757363179

* Small comment changes suggested by @tkoeppe.

* Use `py::set_error()` everywhere possible (only one special case, in common.h).
Overload `py::set_error(py::handle, py::handle)`.
Change back to `static py::handle exc = ... .release();`
Deprecate `py::exception<>::operator()`

* Add `PYBIND11_WARNING_DISABLE` for INTEL and MSVC (and sort alphabetically).

* `PYBIND11_WARNING_DISABLE_INTEL(10441)` does not work.

For ICC only, falling back to the recommended `py::set_error()` to keep the testing simple.

It is troublesome to add `--diag-disable=10441` specifically for test_exceptions.cpp, even that is non-ideal because it covers the entire file, not just the one line we need it for, and the value of exercising the trivial deprecated `operator()` on this one extra platform is practically zero.

* Fix silly oversight.

* NVHPC 23.5.0 generates deprecation warnings. They are currently not treated as errors, but falling back to using `py::set_error()` to not have to deal with that distraction.

    • Add command to check for vX.Y.Z tag vs pybind11/_version.py consistency. (#4757) · f3e06028 
      * Add command to check for vX.Y.Z tag vs pybind11/_version.py consistency. Piggy-backing hints for converting changelog to release message.

* Simpler way of double-checking version number in sources vs. git tag

* Even simpler.

* Fix rst rendering (hopefully) and remove stray dots.

* [ci skip] Trying more to make GitHub rst renderer show this nicely.

* [ci skip] Fix up RST rendering issues.

Lesson learned:

This is NOT GOOD:

```
- Bullet nesting level 1.
    - Bullet nesting level 2.
```

This is BETTER:

```
- Bullet nesting level 1.
  - Bullet nesting level 2.
```

Also consistently adding empty lines between bullet points, to make the .rst
file easier to read.

Also piggy-backing a few very minor enhancements.
