WebAssembly
We continue to work on making our WebAssembly support better. Various sets of issues have been resolved in this release and general performance and feature work is happening as well.
Community improvements for AIX/PASE and Haiku
The ports for these systems received a bunch of improvements from community contributor Calvin Buckley (@NattyNarwhal).
