## Summary
- Add **MicroCeph Tentacle** (v20.2.0) section to
`docs/snap/reference/release-notes.rst` covering core24 base,
microcluster v3 upgrade, log rotation via logrotate, and reference
architecture docs. Scope: 6 PRs that landed on `main` after squid HEAD
diverged.
- Expand the **MicroCeph Squid** section to reflect everything that
shipped on `squid/stable` after the initial v19.2.0 tag (NFS, cluster
adoption, CephFS replication, AZ support, maintenance mode,
orchestrator, DSL device matching, SSL cert modification, `waitready`,
stripingv2, msgr2 enforcement, joiner auto-detect).
- Split the squid PR list into "Squid stable updates (post-v19.2.0)" and
"Initial v19.2.0 release" so readers can tell which features came in
which drop.
