@@ -14,6 +14,7 @@ Docs: https://docs.openclaw.ai
 - Plugin SDK/channel extensibility: expose `channelRuntime` on `ChannelGatewayContext` so external channel plugins can access shared runtime helpers (reply/routing/session/text/media/commands) without internal imports. (#25462) Thanks @guxiaobo.
 - Plugin runtime/events: expose `runtime.events.onAgentEvent` and `runtime.events.onSessionTranscriptUpdate` for extension-side subscriptions, and isolate transcript-listener failures so one faulty listener cannot break the entire update fanout. (#16044) Thanks @scifantastic.
 - Plugin runtime/system: expose `runtime.system.requestHeartbeatNow(...)` so extensions can wake targeted sessions immediately after enqueueing system events. (#19464) Thanks @AustinEral.
+- Plugin hooks/session lifecycle: include `sessionKey` in `session_start`/`session_end` hook events and contexts so plugins can correlate lifecycle callbacks with routing identity. (#26394) Thanks @tempeste.
 - Sessions/Attachments: add inline file attachment support for `sessions_spawn` (subagent runtime only) with base64/utf8 encoding, transcript content redaction, lifecycle cleanup, and configurable limits via `tools.sessions_spawn.attachments`. (#16761) Thanks @napetrov.
 - Tools/PDF analysis: add a first-class `pdf` tool with native Anthropic and Google PDF provider support, extraction fallback for non-native models, configurable defaults (`agents.defaults.pdfModel`, `pdfMaxBytesMb`, `pdfMaxPages`), and docs/tests covering routing, validation, and registration. (#31319) Thanks @tyler6204.
 - Zalo Personal plugin (`@openclaw/zalouser`): rebuilt channel runtime to use native `zca-js` integration in-process, removing external CLI transport usage and keeping QR/login + send/listen flows fully inside OpenClaw.
