Pidgin 3 is currently in pre-alpha, but hopefully it will be ready in
time for Debian 14. More discussion about this is at
https://bugs.debian.org/883214

Pidgin and libpurple 3 is a major API break and everything that uses
it will need changes. Therefore, spectrum2-backend-libpurple will
likely need to be removed later this year unless someone ports it to
work with libpurple 3.

Thank you,
