 - WhatsApp: send captioned `MEDIA:` directive auto-replies once instead of emitting an empty media message before the captioned media reply. (#78770) Thanks @ai-hpc.
 - Hooks/cron: log returned `/hooks/agent` isolated-run errors and failed cron jobs with cron diagnostic summaries, so rejected `payload.model` values are visible instead of looking like accepted-but-missing runs. Fixes #78597. (#78655) Thanks @kevinslin.
 - Managed proxy/security: classify raw socket callsites and proxy runtime mutations in boundary checks so new direct egress or unmanaged proxy-state changes cannot land without explicit review. (#77126) Thanks @jesse-merhi.
+- Agents/subagents: keep omitted thread-bound native `sessions_spawn` context isolated by default, preventing new bound subagent sessions from inheriting requester transcript history unless `fork` is requested. (#78060) Thanks @100yenadmin.
