Recent Releases
2.6.227 Jan 2021 06:05
minor feature:
enum: add missing Enum.value property. #2739.
Allow thread termination to be avoided during shutdown for CPython 3.7+ via.disarm for gil_scoped_acquire/gil_scoped_release. #2657.
where the constructor of object subclasses would not throw on being passed a Python object of the wrong type. #2701.
The type_caster for integers does not convert Python objects with __int__ anymore with noconvert or during the first round of trying overloads. #2698.
When casting to a C++ integer, __index__ is always called and not considered as conversion, consistent with Python 3.8+. #2801.
Setup helpers: extra_compile_args and extra_link_args automatically set by Pybind11Extension are now prepended, which allows them to be overridden by user-set extra_compile_args and extra_link_args. #2808.
Setup helpers: Don't trigger unused parameter warning. #2735.
CMake: Support running with --warn-uninitialized active. #2806.
CMake: Avoid error if included from two submodule directories. #2804.
CMake: STATIC / SHARED being ignored in FindPython mode. #2796.
CMake: Respect the setting for CMAKE_CXX_VISIBILITY_PRESET if defined. #2793.
CMake: with FindPython2/FindPython3 not working with pybind11::embed. #2662.
CMake: mixing local and installed pybind11's would prioritize the installed one over the local one (regression in 2.6.0). #2716.
segfault in multithreaded environments when using scoped_ostream_redirect. #2675.
Leave docstring unset when all docstring-related options are disabled, rather than set an empty string. #2745.
The module key in builtins that pybind11 uses to store its internals changed from std::string to a python str type (more natural on Python 2, no change on Python 3). #2814.
assertion error related to unhandled (later overwritten) exception in CPython 3.8 and 3.9 debuilds. #2685.
py::gil_scoped_acquire assert with CPython 3.9 debuild. #2683.
with a test failing on PyTest 6.2. #2741.
warning modifying constructor parameter 'flag' that shadows a field of 'set_flag'
2.6.112 Nov 2020 03:15
minor feature:
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 lower 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.
2.6.022 Oct 2020 15:05
minor feature:
Keyword-only arguments supported in Python 2 or 3 with py::kw_only(). #2100.
Positional-only arguments supported in Python 2 or 3 with py::pos_only(). #2459.
py::is_final() class modifier to block subclassing (CPython only). #2151.
Added py::prepend(), allowing a function to be placed at the beginning of the overload chain. #1131.
Access to the type object now provided with py::type::of() and py::type::of(h). #2364.
Perfect forwarding support for methods. #2048.
Added py::error_already_set::discard_as_unraisable(). #2372.
py::hash is now public. #2217.
py::class_ is now supported. Note that writing to one data member of the union and reading another (type punning) is UB in C++. Thus pybind11-bound enums should never be used for such conversions. #2320.
Classes now check local scope when registering members, allowing a subclass to have a member with the same name as a parent (such as an enum). #2335.
Error now thrown when __init__ is forgotten on subclasses. #2152.
Throw error if conversion to a pybind11 type if the Python object isn't a valid instance of that type, such as py::bytes(o) when py::object o isn't a bytes instance. #2349.
Throw if conversion to str fails. #2477.
py::module was renamed py::module_ to avoid with C++20 when used unqualified, but an alias py::module is provided for backward compatibility. #2489.
Public constructors for py::module_ have been deprecated; please use pybind11::module_::create_extension_module if you were using the public constructor (fairly rare after PYBIND11_MODULE was introduced). #2552.
PYBIND11_OVERLOAD macros and get_overload function replaced by correctly-named PYBIND11_OVERRIDE and get_override, ing inconsistencies in the presence of a closing ; in these macros. get_type_overload is deprecated. #2325.
The Python package was reworked to be more powerful and useful. #2433
build-setuptools is easier thanks to a new pybind11.setup_helpers module, which provides utilities to use setuptools with pybind11. It c
