Claude Code 2.1.321 and a quick 2.1.322 follow-up are out. I already covered the Fable 5.2 and Mythos 5.2 model launch; this is what changed in the CLI.
2.1.321
- Adds Claude Fable 5.2 (
claude-fable-5-2) and makes it the default Fable model. claude remote-control --settings <file>applies a settings file to every session it starts.- Security-minded fixes: MCP OAuth no longer sends secrets to the wrong host after a redirect, and several sandbox and permission-check holes around Bash,
cp/mvand network paths are tightened.
2.1.322
Adds fast mode on Vertex in the global, us and eu regions, falling back to standard speed if Vertex refuses it.
My take
If you use Fable from the CLI, update so you’re actually on 5.2. The OAuth and sandbox fixes are reason enough even if you don’t.
Review before you install: read the release notes yourself, back up your config, and try new versions somewhere you can afford to break first.
God Bless, and Happy hacking!
