+## [2.2.0] — 2026-07-11
+
+### Added
+
+- **Linux idle sensing.** On Linux the daemon now reads idle state from
+  systemd-logind (IdleHint / IdleSinceHint), mirroring the macOS HID-idle check
+  and working across X11 and Wayland. Contributed by joerybka.
+
+### Fixed
+
+- **More accurate timestamp re-derivation.** `migrate --rederive-timestamps` no
+  longer matches an internal transcript event (e.g. a queue operation) ahead of
+  the real user or assistant turn, so re-derivation stops silently doing nothing
+  on collapsed-timestamp groups. Contributed by joerybka.
