 - macOS/Voice Wake: accept trigger-only phrases in the built-in Voice Wake test, matching the settings UI and runtime trigger-only path instead of requiring extra command text after the wake word. Fixes #64986. Thanks @zoiks65.
 - Cron/TTS: run cron announce payloads through the normal TTS directive transform before outbound delivery, so scheduled `[[tts]]` replies generate voice payloads instead of leaking raw tags. Fixes #52125. Thanks @kenchen3000.
 - WhatsApp: save downloadable quoted image media from reply context as inbound media, so agents can inspect an image that a user replied to instead of only seeing `<media:image>`. Fixes #59174. Thanks @gaffner.
-- Sessions/store: stop persisting the runtime-only `skillsSnapshot.resolvedSkills` array inside each session entry, so `sessions.json` no longer carries a copy of every parsed `SKILL.md` body for every active session; the embedded runner already rebuilds the array from disk when absent and legacy stores self-heal on the next save. Refs #11950, #6650, #15000. Thanks @amoghasgekar.
+- Sessions/store: stop persisting the runtime-only `skillsSnapshot.resolvedSkills` array inside each session entry, so `sessions.json` no longer carries a copy of every parsed `SKILL.md` body for every active session; `ensureSkillSnapshot` rehydrates the array from disk on cold resume so the embedded runner, the Claude CLI skills plugin, and the Claude live-session fingerprint all see populated skills, and legacy stores self-heal on the next save. Refs #11950, #6650, #15000. Thanks @amoghasgekar.
 - Doctor/WhatsApp: warn when Linux crontabs still run the legacy `ensure-whatsapp.sh` health check, which can misreport `Gateway inactive` when cron lacks the systemd user-bus environment. Fixes #60204. Thanks @mySebbe.
 - Slack/setup: print the generated app manifest as plain JSON instead of embedding it inside the framed setup note, so it can be copied into Slack without deleting border characters. Fixes #65751. Thanks @theDanielJLewis.
 - Channels/WhatsApp: route CLI logout through the live Gateway and stop runtime-backed listeners before channel removal, so removing a WhatsApp account does not leave the old socket replying until restart. Fixes #67746. Thanks @123Mismail.
