=========

Unreleased
----------
1.2.1.0 (2026-10-21)
--------------------

- Upgraded libbrotli to v1.2.1, which remediates CVE-2026-111497, an
out-of-bounds write that permits remote code execution.
- Changed one-shot ``decompress()`` and streaming ``Decompressor.process()`` /
``Decompressor.decompress()`` to raise ``brotlicffi.error`` for trailing bytes
after a complete Brotli stream, including calls without an output limit.
