 Notable changes to Swarmail. Versions follow [semantic versioning](https://semver.org).
 
-## Unreleased

-- `swarmail who` asks git about each running T3 thread directory once instead of once per thread. With about 800
-  running threads in 149 directories it took 0.3 s instead of 1.6 s.
-
-- `fetch_inbox` and `fetch_session_inbox` no longer read each message body from storage when `include_bodies` is off,
-  which is the default. A page of 20 messages took 48 µs instead of 57 µs with 2 KB bodies and 52 µs instead of 82 µs
-  with 17 KB bodies.
-
-- The `swarmail-mcp` README lists the memory each launch command costs: about 180 MiB for `npx -y swarmail-mcp`, 82 MiB
-  for `bunx swarmail-mcp` and 46 MiB for `bunx --bun swarmail-mcp`, which runs the same relay under Bun.
