 - BlueBubbles: always set `method` explicitly on outbound text sends (`"private-api"` when available, `"apple-script"` otherwise), and prefer Private API on macOS 26 even for plain text. Fixes silent delivery failure on macOS setups without Private API where an omitted `method` let BB Server fall back to version-dependent default behavior that silently drops the message (#64480), and the AppleScript `-1700` error on macOS 26 Tahoe plain text sends (#53159). (#69070) Thanks @xqing3.
 - Matrix/commands: recognize slash commands that are prefixed with the bot's Matrix mention, so room messages like `@bot:server /new` trigger the command path without requiring custom mention regexes. (#68570) Thanks @nightq and @johnlanni.
 - Agents/subagents: include requested role and runtime timing on subagent failure payloads so parent agents can correlate failed or timed-out child work. (#68726) Thanks @BKF-Gitty.
+- Gateway/sessions: reject stale agent-scoped sessions after an agent is removed from config while preserving legacy default-agent main-session aliases. (#65986) Thanks @bittoby.

 - Active Memory: raise the blocking recall timeout ceiling to 120 seconds and reject larger config values during plugin schema validation. Fixes #68410. (#68480) Thanks @Bartok9.
 - Control UI/chat: keep history-backed user image uploads visible after chat reload while filtering blocked or non-image transcript media paths. (#68415) Thanks @mraleko.
 - Matrix/plugins: keep remaining Matrix event helpers on the canonical `matrix-js-sdk` subpath so build and plugin-load entrypoint checks stay consistent. (#68498) Thanks @masatohoshino.
