 ### Fixes
 
 - TUI/stream assembly: preserve streamed text across real tool-boundary drops without keeping stale streamed text when non-text blocks appear only in the final payload. Landed from contributor PR #27711 by @scz2011. (#27674)
+- Hooks/Internal `message:sent`: forward `sessionKey` on outbound sends from agent delivery, cron isolated delivery, gateway receipt acks, heartbeat sends, session-maintenance warnings, and restart-sentinel recovery so internal `message:sent` hooks consistently dispatch with session context. Landed from contributor PR #27584 by @qualiobra. Thanks @qualiobra.
 - Models/MiniMax auth header defaults: set `authHeader: true` for both onboarding-generated MiniMax API providers and implicit built-in MiniMax (`minimax`, `minimax-portal`) provider templates so first requests no longer fail with MiniMax `401 authentication_error` due to missing `Authorization` header. Landed from contributor PRs #27622 by @riccoyuanft and #27631 by @kevinWangSheng. (#27600, #15303)
 - Pi image-token usage: stop re-injecting history image blocks each turn, process image references from the current prompt only, and prune already-answered user-image blocks in stored history to prevent runaway token growth. (#27602)
 - BlueBubbles/SSRF: auto-allowlist the configured `serverUrl` hostname for attachment fetches so localhost/private-IP BlueBubbles setups are no longer false-blocked by default SSRF checks. Landed from contributor PR #27648 by @lailoo. (#27599) Thanks @taylorhou for reporting.
