What

Several small, unrelated additions appear in this build:

  • A send tool's result now ends with the message's ID when one is available.
  • A new name for gzip-compressed log shipping is added to an internal list.
  • A database quota category gains a per-database byte limit.
  • The color theme gains a shimmer color tied to auto-accept.
  • A telemetry record (usage data Claude Code reports) gains a count of carried writes.
  • A settings schema gains a people_writable field, which is false by default.
Why

Most of these are early signs of work in progress, such as compressed log shipping and byte limits per database, rather than features you can use today.
