• Prevent concurrent creation of sub-interpreters as a workaround for stdlib concurrency issues in Python 3.12. #5779
• Fixed potential crash when using cpp_function objects with sub-interpreters. #5771
• Fixed non-entrant check in implicitly_convertible(). #5777
• Support C++20 on platforms that have older c++ runtimes. #5761
• Fix compilation with clang on msys2. #5757

Documentation:

• Improve buffer_info type checking in numpy docs. #5805
• Replace robotpy-build with semiwrap in the binding tool list. #5804
• Show nogil in most examples. #5770
• Fix py::trampoline_self_life_support visibility in docs. #5766

Tests:

• Rename internal variables to avoid the word slots (reads better). #5793

Version 3.0.0

Pybind11 3.0 includes an ABI bump, the first required bump in many years on Unix (Windows has had required bumps more often). This release contains the smart-holder branch, multi-phase init and subinterpreter support, py::native_enum, an interface to warnings, typing improvements, and more. CMake now defaults to FindPython mode. Please check our upgrade guide for more info on upgrading!

Support for Python 3.14, 3.14t, GraalPy, and PyPy 3.11 has been added, while legacy support for Python 3.7, PyPy 3.8/3.9, and CMake <3.15 has been removed. Most deprecated features have been kept for this release, but anything producing a warning in 3.0 may be removed in a future 3.x version. We also now have a deprecation page.
