 - Gmail: add `gmail autoreply` to reply once to matching messages, label the thread for dedupe, and optionally archive/mark read. Includes docs and regression coverage for skip/reply flows.
 
 ### Fixed
+- Calendar: avoid ambiguous timezone guessing from offset-only event times, preserve timezones for focus-time events, and use exclusive next-midnight bounds for full-day ranges. (#492, #509, #510) — thanks @RaphaelRUzan and @dinakars777.
+- Gmail: avoid re-decoding Gmail-normalized UTF-8 bodies through stale MIME charset headers while preserving ISO-2022-JP decoding. (#511) — thanks @dinakars777.
+- Tasks: clear task due dates when `tasks update --due=` is provided. (#507) — thanks @dinakars777.
 - Docs: use UTF-16 offsets for sed formatting ranges and preserve `&` whole-match replacements. (#483) — thanks @bill492.
 - Gmail: encode plain-text send bodies as quoted-printable so long lines are not hard-wrapped in transit. (#476) — thanks @shashankkr9.
 - Contacts: reject all individual update flags when `contacts update --from-file` is used. (#439) — thanks @klodr.
