 ## [Unreleased]
 
+## [1.2.0] - 2026-08-22
+
+### Added
+
+- Fleet-wide agent updates are now discoverable from Settings and the
+  dashboard, with arbitrary host subsets, name/tag/version/eligibility
+  filtering, explicit exclusion reasons, server-side membership validation,
+  and a canary-first pause after the first verified reconnect. Halted rolls
+  expose retry and resume actions. ([#43])
+- Running jobs with no recent persisted activity are detected server-side and
+  surfaced through deduplicated alerts. Kind-aware thresholds protect normal
+  long-running work, terminal jobs self-resolve, and Prometheus exports stuck
+  job count and oldest inactivity age. ([#41])
+- Snapshot projections now retain host-level refresh timestamps—including
+  authoritative empty reports—expose a derived stale flag, refresh after
+  backup, forget, and prune, and support an explicit operator reconciliation
+  endpoint. ([#40])
+
+### Fixed
+
+- Raised the bounded WebSocket read limit on both peers so ordinary large
+  snapshot reports and restic events no longer disconnect otherwise healthy
+  agents. Regression coverage exercises payloads beyond the library's former
+  32 KiB default in both directions. ([#44])
+- Fleet-update timeout verification now performs a final authoritative read of
+  the agent version delivered by the reconnect `hello`, avoiding a poll/deadline
+  race and reporting the last observed version when verification fails. ([#43])
+
+### Changed
+
+- CI runner images and release images use the anonymous-pull `public`
+  namespace at `docker.dcglab.co.uk`; registry authentication remains required
+  only for publishing.
