 - CI/channel test routing: move the built-in channel suites into `test:channels` and keep them out of `test:extensions`, so extension CI no longer fails after the channel migration while targeted test routing still sends Slack, Signal, and iMessage suites to the right lane. (#46066) Thanks @scoootscooob.
 - Docs/Mintlify: fix MDX marker syntax on Perplexity, Model Providers, Moonshot, and exec approvals pages so local docs preview no longer breaks rendering or leaves stale pages unpublished. (#46695) Thanks @velvet-shark.
 - Gateway/config validation: stop treating the implicit default memory slot as a required explicit plugin config, so startup no longer fails with `plugins.slots.memory: plugin not found: memory-core` when `memory-core` was only inferred. (#47494) Thanks @ngutman.
+- xAI/models: rename the bundled Grok 4.20 catalog entries to the GA IDs and normalize saved deprecated beta IDs at runtime so existing configs and sessions keep resolving. (#50772) thanks @Jaaneek
 - Tlon: honor explicit empty allowlists and defer cite expansion. (#46788) Thanks @zpbrent and @vincentkoc.
 - Tlon/DM auth: defer cited-message expansion until after DM authorization and owner command handling, so unauthorized DMs and owner approval/admin commands no longer trigger cross-channel cite fetches before the deny or command path.
 - Gateway/agent events: stop broadcasting false end-of-run `seq gap` errors to clients, and isolate node-driven ingress turns with per-turn run IDs so stale tail events cannot leak into later session runs. (#43751) Thanks @caesargattuso.
