 ### Fixed
 - Calendar: respond patches only attendees to avoid custom reminders validation errors. (#265) — thanks @sebasrodriguez.
+- Contacts: fix grouped parameter types in CRUD helpers to restore builds on newer Go toolchains. (#355) — thanks @laihenyi.
+- Timezone: embed the IANA timezone database so Windows builds can resolve calendar timezones correctly. (#388) — thanks @visionik.
+- Gmail: add a fetch delay in `watch serve` so History API reads don't race message indexing. (#397) — thanks @salmonumbrella.
 - Secrets: respect empty `GOG_KEYRING_PASSWORD` (treat set-to-empty as intentional; avoids headless prompts). (#269) — thanks @zerone0x.
 - Calendar: reject ambiguous calendar-name selectors for `calendar events` instead of guessing. (#131) — thanks @salmonumbrella.
 - Gmail: `drafts update --quote` now picks a non-draft, non-self message from thread fallback (or errors clearly), avoiding self-quote loops and wrong reply headers. (#394) — thanks @salmonumbrella.
