+.. rubric:: 6 June 2025

+This is a bugfix release, still wrapping htslib/samtools/bcftools 1.21.
+
+It has been tested with Python versions 3.8 through 3.13, and wheels are
+available via PyPI_ for all of those Python versions. Wheels are built for
+macOS and Linux (manylinux_2_28 and musllinux_1_2) on both ARM and x86-64.

 * Pysam 0.23.1 inadvertently broke binary compatibility for Cython projects
   by changing the size of :class:`.AlignedSegment`. That class has been
   restored to its previous size, so v0.23.2 restores binary compatibility
