+This package is designed to run with Python 3.8, 3.9, 3.10, and 3.11
 on common platforms (Linux, Windows, and OS X). On PyPy (both PyPy2 and PyPy3)
 we support version 6.0.0 and above. x86 and x86_64 are well-tested on Windows.
 Only x86_64 is well-tested on Linux and macOS.

   is no longer supported by the pypa/manylinux project.
 * Removed CI coverage for PyPy 3.7 and 3.8, which are no longer supported
   PyPy versions.
+* Support for Python 3.7 has been dropped because it reached end of life.
+  Python 3.8 is the minimum supported Python version. The code should still be
+  compatible with Python 3.7 and removing of version checks from ``setup.py``
+  will likely yield a working install. However, this is no officially supported.

+Bug Fixes
+---------
+
+* ``ZstdDecompressor.decompress()`` with ``allow_extra_data=False`` would
+  previously allow extra data to exist after an *empty* zstd frame (a frame
+  holding 0 length input). This scenario now raises an exception.
