* Shorten changelog entry for PR 5862

* Remove mention of a minor doc formatting fix.

* Cursor-generated "all past-tense" style

* Restore the meaning of the 5958 entry using the "... now ..." trick, and restore a couple other entries that also use the "now" trick.

* Replace ... now ... style with ... updated to ... style

+## Version 3.0.2 (release date TBD)
+
+Bug fixes:
+
+- MSVC 19.16 and earlier were blocked from using `std::launder` due to internal compiler errors.
+  [#5968](https://github.com/pybind/pybind11/pull/5968)
+
+- Internals destructors were updated to check the owning interpreter before clearing Python objects.
+  [#5965](https://github.com/pybind/pybind11/pull/5965)
+
+- pybind11 internals were updated to be deallocated during (sub-)interpreter shutdown to avoid memory leaks.
+  [#5958](https://github.com/pybind/pybind11/pull/5958)
+
+- Fixed ambiguous `str(handle)` construction for `object`-derived types like `kwargs` or `dict` by templatizing the constructor with SFINAE.
+  [#5949](https://github.com/pybind/pybind11/pull/5949)
+
+- Fixed concurrency consistency for `internals_pp_manager` under multiple-interpreters.
+  [#5947](https://github.com/pybind/pybind11/pull/5947)
+
+- Fixed MSVC LNK2001 in C++20 builds when /GL (whole program optimization) is enabled.
+  [#5939](https://github.com/pybind/pybind11/pull/5939)
+
+- Added per-interpreter storage for `gil_safe_call_once_and_store` to make it safe under multi-interpreters.
+  [#5933](https://github.com/pybind/pybind11/pull/5933)
+
+- A workaround for a GCC `-Warray-bounds` false positive in `argument_vector` was added.
+  [#5908](https://github.com/pybind/pybind11/pull/5908)
+
+- Corrected a mistake where support for `__index__` was added, but the type hints did not reflect acceptance of `SupportsIndex` objects. Also fixed a long-standing bug: the complex-caster did not accept `__index__` in `convert` mode.
+  [#5891](https://github.com/pybind/pybind11/pull/5891)
+
+- Fixed `*args/**kwargs` return types. Added type hinting to `py::make_tuple`.
+  [#5881](https://github.com/pybind/pybind11/pull/5881)
+
+- Fixed compiler error in `type_caster_generic` when casting a `T` implicitly convertible from `T*`.
+  [#5873](https://github.com/pybind/pybind11/pull/5873)
+
+- Updated `py::native_enum` bindings to unregister enum types on destruction, preventing a use-after-free when returning a destroyed enum instance.
+  [#5871](https://github.com/pybind/pybind11/pull/5871)
+
+- Fixed undefined behavior that occurred when importing pybind11 modules from non-main threads created by C API modules or embedded python interpreters.
+  [#5870](https://github.com/pybind/pybind11/pull/5870)
+
+- Fixed dangling pointer in `internals::registered_types_cpp_fast`.
+  [#5867](https://github.com/pybind/pybind11/pull/5867)
+
+- Added support for `std::shared_ptr<T>` when loading module-local or conduit types from other modules.
+  [#5862](https://github.com/pybind/pybind11/pull/5862)
+
+- Fixed thread-safety issues if types were concurrently registered while `get_local_type_info()` was called in free threaded Python.
+  [#5856](https://github.com/pybind/pybind11/pull/5856)
+
+- Fixed py::float_ casting and py::int_ and py::float_ type hints.
+  [#5839](https://github.com/pybind/pybind11/pull/5839)
+
+- Fixed two `smart_holder` bugs in `shared_ptr` and `unique_ptr` adoption with multiple/virtual inheritance:
+    - `shared_ptr` to-Python caster was updated to register the correct subobject pointer (fixes #5786).
+    - `unique_ptr` adoption was updated to own the proper object start while aliasing subobject pointers for registration, which fixed MSVC crashes during destruction.
+  [#5836](https://github.com/pybind/pybind11/pull/5836)
+
+- Constrained `accessor::operator=` templates to avoid obscuring special members.
+  [#5832](https://github.com/pybind/pybind11/pull/5832)
+
+- Fixed crash that can occur when finalizers acquire and release the GIL.
+  [#5828](https://github.com/pybind/pybind11/pull/5828)
+
+- Fixed compiler detection in `pybind11/detail/pybind11_namespace_macros.h` for clang-cl on Windows, to address warning suppression macros.
+  [#5816](https://github.com/pybind/pybind11/pull/5816)
+
+- Fixed compatibility with CMake policy CMP0190 by not always requiring a Python interpreter when cross-compiling.
+  [#5829](https://github.com/pybind/pybind11/pull/5829)
+
+- Added a static assertion to disallow `keep_alive` and `call_guard` on properties.
+  [#5533](https://github.com/pybind/pybind11/pull/5533)
+

+  [#5930](https://github.com/pybind/pybind11/pull/5930)

+
+- Updated `.gitignore` to exclude `__pycache__/` directories.
+  [#5838](https://github.com/pybind/pybind11/pull/5838)
+
+- Changed internals to use `thread_local` instead of `thread_specific_storage` for increased performance.
+  [#5834](https://github.com/pybind/pybind11/pull/5834)
+
+- Reduced function call overhead by using thread_local for loader_life_support when possible.
+  [#5830](https://github.com/pybind/pybind11/pull/5830)
+
+- Removed heap allocation for the C++ argument array when dispatching functions with 6 or fewer arguments.
+  [#5824](https://github.com/pybind/pybind11/pull/5824)
+
+
+Documentation:
+
+- Fixed docstring for `long double` complex types to use `numpy.clongdouble` instead of the deprecated `numpy.longcomplex` (removed in NumPy 2.0).
+  [#5952](https://github.com/pybind/pybind11/pull/5952)
+
+- The "Supported compilers" and "Supported platforms" sections in the main `README.rst` were replaced with a new "Supported platforms & compilers" section that points to the CI test matrix as the living source of truth.

+CI:
+
+- Added CI tests for windows-11-arm with clang/MSVC (currently python 3.13), windows-11-arm with clang/mingw (currently python 3.12).
