- WhatsApp: transcribe accepted voice notes before agent dispatch while keeping spoken transcripts out of command authorization. (#64120) Thanks @rogerdigital.

- Plugins/CLI: expose channel plugin CLI descriptors during discovery-mode plugin loads so snapshot registries keep channel commands visible without activating full runtimes. (#71309) Thanks @gumadeiras.

- WhatsApp: deliver media generated by tool-result replies while still suppressing text-only tool chatter. (#60968) Thanks @adaclaw.

- Config/agents: accept `agents.list[].contextTokens` in strict config validation so per-agent overrides survive hot reload, letting `/status` reflect the configured model window instead of the 200k fallback. Fixes #70692. (#71247) Thanks @statxc.
