  Changes
 =========
 
-3.2.5 (unreleased)
+3.3.0 (unreleased)
 ==================
 
-- Nothing changed yet.
+- Drop support for Python 3.9.
+- Switch to distributing manylinux_2_28 wheels instead of
+  manylinux2014 wheels. Likewise, switch from musllinux_1_1 to 1_2.
+- Add initial support for free-threaded builds of CPython 3.14. Due to
+  limitations, we do not distribute binary wheels for free-threaded
+  CPython on Windows. (Free-threaded CPython 3.13 may work, but is
+  untested and unsupported.)
