Not immediately up-to-date at all times, but I use backports. Looks like they’re only a point release behind still. https://packages.debian.org/bookworm-backports/libreoffice

The only time it gets behind by a full version is if Debian Stable is really long in the tooth and Backports can’t compile something due to a compiler or library being really old or if Backports hasn’t been created yet because Stable is young.

Once I started using the tool lending libraries in the San Francisco East Bay, it was a game changer for simple maintenance.
