Just a heads up in case this is unintentional. For all versions prior to 2.24, an accompanying source tarball was uploaded to musicpd.org, and this page was updated to reflect the release: https://musicpd.org/libs/libmpdclient/
This doesn't seem to have happened for 2.24.
I also notice the online documentation at https://musicpd.org/doc/libmpdclient/ doesn't seem to have been updated since 2.22.
