Hello,

Here is a diff for net/mautrix-whatsapp 0.12.5.

There is a reminder about the @lid migration WhatsApp is doing that was 
mentioned in the v0.12.0, v0.12.2 and v0.12.3 release notes: the 
registration.yaml file must have .+ (or .*) instead of [0-9]+ in the 
user ID regex, e.g. @whatsapp_.+:example\.com. If you set up the bridge 
prior to v0.5.0 and do not fix your registration file, group chats will 
gradually stop working as WhatsApp migrates them to use LIDs.

Tested on amd64
