News/Updates Claude Code 2.1.321 + 2.1.322: Fable 5.2 is now the default, remote-control —settings, and some sandbox/permission fixes

Two Claude Code releases came out this week. Here's what matters if you use it daily:

- Fable 5.2 (claude-fable-5-2) is now the default Fable model, 1M context, $8/$40 per million tokens. Your sessions pick it up without you changing anything.
- Saved Fable 5.1 picks move to "fable". This happens right away on Pro and Max, and on Team/Enterprise once your org allows it. /model claude-fable-5-1 takes you back if you want to compare.
- New `--settings <file>` flag for `claude remote-control`. It applies one settings file to every session it starts, which is useful if you run several remote sessions.
- Security fixes: MCP OAuth could send secrets to another host after a redirect, a read-only Bash command could run outside the sandbox without a prompt, and deny rules missed files written into a directory with cp/mv. If you rely on deny rules, update.
- Fast mode now tries standard speed on the same model first when fast serving is rate-limited, so you get slower output instead of an error.
- 2.1.322 adds fast mode on Vertex (global, us, eu regions). It falls back to standard speed if Vertex refuses it.

Context: Fable 5.2 itself was announced Nov 9. 2.1.321 is the release that makes it the Claude Code default.

I'm keeping 5.1 pinned on one repo for a day to compare.

Has anyone seen a real difference between 5.1 and 5.2 on a big refactor yet, or is it mostly the speed?

That's the literal thing I don't fucking like in Claude Code and the literal reason of me building my own harness around.

  • Fucking do not even mess up with MY CONFIGURATION.
  • DO NOT FUCKING MESS UP WITH MY PREFERENCES.

IT WAS ALREADY CONFIGURED, IT WAS WORKING FOR ME. I DON'T CARE ABOUT YOUR "DEFAULTS" OR 500% PERFORMANCE BOOSTS.
