+Unreleased
+----------
+
+* Bumped MSRV to 1.85.
+
+5.0.0
+-----
+
+* Bumped MSRV to 1.74.
+* Added support for Python 3.14 and free-threaded Python 3.14.
+* Added support for Windows on ARM.
+* Passing ``hashpw`` a password longer than 72 bytes now raises a
+  ``ValueError``. Previously the password was silently truncated, following the
+  behavior of the original OpenBSD ``bcrypt`` implementation.
+
+4.3.0
+-----
+
+* Dropped support for Python 3.7.
+* We now support free-threaded Python 3.13.
+* We now support PyPy 3.11.
+* We now publish wheels for free-threaded Python 3.13, for PyPy 3.11 on
+  ``manylinux``, and for ARMv7l on ``manylinux``.
+
+4.2.1
+-----
+
+* Bump Rust dependency versions - this should resolve crashes on Python 3.13
+  free-threaded builds.
+* We no longer build ``manylinux`` wheels for PyPy 3.9.
+
+4.2.0
+-----
+
+* Bump Rust dependency versions
+* Removed the ``BCRYPT_ALLOW_RUST_163`` environment variable.
+
+4.1.3
+-----
+
+* Bump Rust dependency versions
+
+4.1.2
+-----
+
+* Publish both ``py37`` and ``py39`` wheels. This should resolve some errors
+  relating to initializing a module multiple times per process.
+
+4.1.1
+-----
+
+* Fixed the type signature on the ``kdf`` method.
+* Fixed packaging bug on Windows.
+* Fixed incompatibility with passlib package detection assumptions.
+
+4.1.0
+-----
+
+* Dropped support for Python 3.6.
+* Bumped MSRV to 1.64. (Note: Rust 1.63 can be used by setting the ``BCRYPT_ALLOW_RUST_163`` environment variable)
+
+4.0.1
+-----
+
+* We now build PyPy ``manylinux`` wheels.
+* Fixed a bug where passing an invalid ``salt`` to ``checkpw`` could result in
+  a ``pyo3_runtime.PanicException``. It now correctly raises a ``ValueError``.
+
+4.0.0
+-----
+
+* ``bcrypt`` is now implemented in Rust. Users building from source will need
+  to have a Rust compiler available. Nothing will change for users downloading
+  wheels.
+* We no longer ship ``manylinux2010`` wheels. Users should upgrade to the latest
+  ``pip`` to ensure this doesn’t cause issues downloading wheels on their
+  platform. We now ship ``manylinux_2_28`` wheels for users on new enough platforms.
+* ``NUL`` bytes are now allowed in inputs.
+
+
+3.2.2
+-----
+
+* Fixed packaging of ``py.typed`` files in wheels so that ``mypy`` works.
+
+3.2.1
+-----
+
+* Added support for compilation on z/OS
+* The next release of ``bcrypt`` with be 4.0 and it will require Rust at
+  compile time, for users building from source. There will be no additional
+  requirement for users who are installing from wheels. Users on most
+  platforms will be able to obtain a wheel by making sure they have an up to
+  date ``pip``. The minimum supported Rust version will be 1.56.0.
+* This will be the final release for which we ship ``manylinux2010`` wheels.
+  Going forward the minimum supported manylinux ABI for our wheels will be
+  ``manylinux2014``. The vast majority of users will continue to receive
+  ``manylinux`` wheels provided they have an up to date ``pip``.
+
+
+3.2.0
+-----
+
+* Added typehints for library functions.
+* Dropped support for Python versions less than 3.6 (2.7, 3.4, 3.5).
+* Shipped ``abi3`` Windows wheels (requires pip >= 20).
+
+3.1.7
+-----
+
+* Set a ``setuptools`` lower bound for PEP517 wheel building.
+* We no longer distribute 32-bit ``manylinux1`` wheels. Continuing to produce
+  them was a maintenance burden.
+
+3.1.6
+-----
+
+* Added support for compilation on Haiku.
+
+3.1.5
+-----
+
+* Added support for compilation on AIX.
+* Dropped Python 2.6 and 3.3 support.
+* Switched to using ``abi3`` wheels for Python 3. If you are not getting a
+  wheel on a compatible platform please upgrade your ``pip`` version.
+
+3.1.4
+-----
+
+* Fixed compilation with mingw and on illumos.
+
+3.1.3
+-----
+* Fixed a compilation issue on Solaris.

+* Fixed a compile issue affecting big endian platforms.
+* Fixed invalid escape sequence warnings on Python 3.6.
+* Fixed building in non-UTF8 environments on Python 2.
+
+3.1.1
+-----
+* Resolved a ``UserWarning`` when used with ``cffi`` 1.8.3.
+
+3.1.0
+-----
+* Added support for ``checkpw``, a convenience method for verifying a password.
+* Ensure that you get a ``$2y$`` hash when you input a ``$2y$`` salt.
+* Fixed a regression where ``$2a`` hashes were vulnerable to a wraparound bug.
+* Fixed compilation under Alpine Linux.
+
+3.0.0
+-----
+* Switched the C backend to code obtained from the OpenBSD project rather than
+  openwall.
+* Added support for ``bcrypt_pbkdf`` via the ``kdf`` function.
