 version 1.0.0-dev
 ------------------
++ Wheels are now always build with nasm for the x86 architecture. Previously
+  yasm was used for Linux and MacOS due to build issues that have since been
+  fixed upstream.
++ Updated statically included ISA-L to version 2.31.0. This fixes the bug
+  mentioned below in python-isal as well.
++ Fixed a bug upstream in ISA-L were zlib headers would be created with an
+  incorrect wbits value.
 + Python-isal shows up in Python profiler reports.
 + Support and tests for Python 3.10 were added.
 + Due to a change in the deployment process wheels should work for older
