 **Enhancements**
 
+- 2126_, [Linux]: build and test ``musllinux`` wheels.  (patch by Ben Raz)
 - 2343_, [FreeBSD]: filter `net_connections()`_ returned list in C instead of
   Python, and avoid to retrieve unnecessary connection types unless explicitly
   asked. E.g., on an IDLE system with few IPv6 connections this will run around
