Claude – v2.1.321

What’s in this update

What's changed

• Added Claude Fable 5.2 (claude-fable-5-2), now the default Fable model — 1M context, $8/$40 per Mtok with $0.20/Mtok cache reads
• Added --settings <file> to claude remote-control, which applies a settings file to every session it starts; if the file changes, no new session starts until you restart claude remote-control
• Fixed MCP OAuth requests sending secrets such as refresh tokens to another host when a server redirected them
• Fixed a case where a read-only Bash command ran outside the sandbox without a permission prompt
• Fixed a case where Bash permission checks judged a file write from the wrong folder and didn't prompt
• Fixed deny rules and protected-file prompts not applying to the file that a cp or mv into a directory writes
• Fixed the "Draws from usage credits" note showing after a switch to Fable on Enterprise seats whose plan includes Fable
• Fixed the fallback model sometimes declining a request or mentioning a stopped response when the first model was blocked before replying
• Fixed claude mcp login printing a SEP-2352 issuer warning each time you sign in again to a server that Claude Code registered with
• Fixed NotebookEdit deleting or overwriting a notebook's first cell when the call named no cell, on network paths (UNC shares, WSL folders, /net mounts)
