@@ -19,6 +19,7 @@ Docs: https://docs.openclaw.ai
 - Plugins/doctor: repair missing configured provider and channel plugins from ClawHub before npm fallback, preserving ClawPack metadata in the install record. Thanks @vincentkoc.
 - Gateway/channels: cap startup fanout at four channel/account handoffs and recover from Bonjour ciao self-probe races, reducing Windows startup stalls with many Telegram accounts. Fixes #75687.
 - Gateway/sessions: keep `sessions.list` polling responsive on large session stores by reusing list-safe session cache/indexes and returning a lightweight compaction checkpoint preview instead of heavyweight summaries. Thanks @rolandrscheel.
+- Control UI/Gateway: keep long-running dashboard WebSocket sessions alive with protocol pings and keep Stop available after reconnect or reload by recovering session-scoped active-run abort state. Fixes #70991. Thanks @alexandre-leng.
 - CLI/update: treat inherited Gateway service markers as origin hints and only block package replacement when the managed Gateway is still live, so self-updates can stop the service and continue safely. (#75729) Thanks @hxy91819.
 - Agents/failover: exempt run-level timeouts that fire during tool execution from model fallback, timeout-triggered compaction, and generic timeout payload synthesis. Long `process(poll)`, browser, or `exec` tool calls that exceed `agents.defaults.timeoutSeconds` previously rotated auth profiles, switched to a fallback model, and surfaced a misleading "LLM request timed out" error even though the primary model had already responded. Mirrors the existing `timedOutDuringCompaction` precedent (#46889). Fixes #52147. (#75873) Thanks @simonusa.
 - Docker: copy Bun 1.3.13 from a digest-pinned image and keep CI on the same version. Fixes #74356. Thanks @fede-kamel and @sallyom.
