* Add option to force the use of the PYPY GIL scoped acquire/release logic to support nested gil access, see https://github.com/pybind/pybind11/issues/1276 and https://github.com/pytorch/pytorch/issues/83101 * Apply suggestions from code review * Update CMakeLists.txt * docs: update upgrade guide * Update docs/upgrade.rst * All bells & whistles. * Add Reminder to common.h, so that we will not forget to purge `!WITH_THREAD` branches when dropping Python 3.6 * New sentence instead of semicolon. * Temporarily pull in snapshot of PR #4246 * Add `test_release_acquire` * Add more unit tests for nested gil locking * Add test_report_builtins_internals_keys * Very minor enhancement: sort list only after filtering. * Revert change in docs/upgrade.rst * Add test_multi_acquire_release_cross_module, while also forcing unique PYBIND11_INTERNALS_VERSION for cross_module_gil_utils.cpp * Hopefully fix apparently new ICC error. ``` 2022-10-28T07:57:54.5187728Z -- The CXX compiler identification is Intel 2021.7.0.20220726 ... 2022-10-28T07:58:53.6758994Z icpc: remark #10441: The Intel(R) C++ Compiler Classic (ICC) is deprecated and will be removed from product release in the second half of 2023.
