• py::exec, py::eval, and py::eval_file now add the builtins module as "__builtins__" to their globals argument, better matching exec and eval in pure Python. #2616
• setup_helpers will no longer set a minimum macOS version higher than the current version. #2622
• Allow deleting static properties. #2629
• Seal a leak in def_buffer, cleaning up the capture object after the class_ object goes out of scope.
  #2634
• pybind11_INCLUDE_DIRS was incorrect, potentially causing a regression if it was expected to include PYTHON_INCLUDE_DIRS (please use targets instead). #2636
• Added parameter names to the py::enum_ constructor and methods, avoiding arg0 in the generated docstrings. #2637
• Added needs_recompile optional function to the ParallelCompiler helper, to allow a recompile to be skipped based on a user-defined function. #2643
