• Agent Signal nightly self-review — Wired self-review loop with prompt + DB support, exponential-backoff retry on receipt listing, skill-aware policy, and improved skill-intent detection. (#14543, [#14542], [#14281], [#14409], [#14526], [#14437])
• Inline documents in KB tool — BM25 search and docs_* read for inline document grounding; agent documents usable as VFS. (#14494, [#14222])
• Inline agent cards in chat — lobeAgents markdown tag renders agent profile cards inline; clickable card after createAgent. (#14495, [#14493])
• Heterogeneous agent runtime — Cloud hetero exec pipeline steps 3+4 land, persistence recovers across Vercel replicas, server-side ingest/finish handler, and lh hetero exec CLI. (#14486, [#14539], [#14444], [#14431])
• Bot platforms expand — Messager, Line, DM pair policy, and messenger DB tables; Telegram API path restored. (#14442, [#14207], [#14211], [#14496], [#14519])
