CHANGELOG.md

@@ -33,6 +33,22 @@ Docs: https://docs.openclaw.ai
 - Gateway/tailscale: start Tailscale exposure and the gateway update check before awaiting channel and plugin sidecar startup so remote operators are not locked out when startup sidecars stall.
 - QQBot/streaming: make block streaming configurable per QQ bot account via `streaming.mode` (`"partial"` | `"off"`, default `"partial"`) instead of hardcoding it off, so responses can be delivered incrementally. (#63746)
 - Dreaming/gateway: require `operator.admin` for persistent `/dreaming on|off` changes and treat missing gateway client scopes as unprivileged instead of silently allowing config writes. (#63872) Thanks @mbelinky.
+- Matrix/multi-account: keep room-level `account` scoping, inherited room overrides, and implicit account selection consistent across top-level default auth, named accounts, and cached-credential env setups. (#58449) thanks @Daanvdplas and @gumadeiras.
+- Gateway/pairing: prefer explicit QR bootstrap auth over earlier Tailscale auth classification so iOS `/pair qr` silent bootstrap pairing does not fall through to `pairing required`. (#59232) Thanks @ngutman.
+- Config/Discord: coerce safe integer numeric Discord IDs to strings during config validation, keep unsafe or precision-losing numeric snowflakes rejected, and align `openclaw doctor` repair guidance with the same fail-closed behavior. (#45125) Thanks @moliendocode.
+- Gateway/sessions: scope bare `sessions.create` aliases like `main` to the requested agent while preserving the canonical `global` and `unknown` sentinel keys. (#58207) thanks @jalehman.
+- `/context detail` now compares the tracked prompt estimate with cached context usage and surfaces untracked provider/runtime overhead when present. (#28391) thanks @ImLukeF.
+- Gateway/session reset: emit the typed `before_reset` hook for gateway `/new` and `/reset`, preserving reset-hook behavior even when the previous transcript has already been archived. (#53872) thanks @VACInc
+- Plugins/commands: pass the active host `sessionKey` into plugin command contexts, and include `sessionId` when it is already available from the active session entry, so bundled and third-party commands can resolve the current conversation reliably. (#59044) Thanks @jalehman.
+- Agents/auth: honor `models.providers.*.authHeader` for pi embedded runner model requests by injecting `Authorization: Bearer <apiKey>` when requested. (#54390) Thanks @lndyzwdxhs.
+- UI/compaction: keep the compaction indicator in a retry-pending state until the run actually finishes, so the UI does not show `Context compacted` before compaction actually finishes. (#55132) Thanks @mpz4life.
+- Cron/tool schemas: keep cron tool schemas strict-model-friendly while still preserving `failureAlert=false`, nullable `agentId`/`sessionKey`, and flattened add/update recovery for the newly exposed cron job fields. (#55043) Thanks @brunolorente.
+- BlueBubbles/config: accept `enrichGroupParticipantsFromContacts` in the core strict config schema so gateways no longer fail validation or startup when the BlueBubbles plugin writes that field. (#56889) Thanks @zqchris.
+- Agents/failover: classify AbortError and stream-abort messages as timeout so Ollama NDJSON stream aborts stop showing `reason=unknown` in model fallback logs. (#58324) Thanks @yelog
+- Exec approvals: route Slack, Discord, and Telegram approvals through the shared channel approval-capability path so native approval auth, delivery, and `/approve` handling stay aligned across channels while preserving Telegram session-key agent filtering. (#58634) thanks @gumadeiras
+- Matrix/runtime: resolve the verification/bootstrap runtime from a distinct packaged Matrix entry so global npm installs stop failing on crypto bootstrap with missing-module or recursive runtime alias errors. (#59249) Thanks @gumadeiras.
+- Matrix/streaming: preserve ordered block flushes before tool, message, and agent boundaries, add explicit `channels.matrix.blockStreaming` opt-in so Matrix `streaming: "off"` stays final-only by default, and move MiniMax plain-text final handling into the MiniMax provider runtime instead of the shared core heuristic. (#59266) thanks @gumadeiras
+- Gateway/agents: fix stale run-context TTL cleanup so the new maintenance sweep compiles and resets orphaned run sequence state correctly. (#52731) thanks @artwalker
