+  - a script has been added (`contrib/whatsmeow-backport.bash`) which modifies the most recent whatsmeow version to accept golang 1.24, by taking the most recent commits from its dependencies prior to their own upgrades to 1.25.  This should allow for more versatility in packaging a release, and fixes ([#220](https://github.com/matterbridge-org/matterbridge/issues/220))
