# Claude Code v2.1.318

> Claude Code v2.1.318, released 3 Nov 2026 (2026-11-03). 425 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

[Web version](https://changelogs.core-directive.com/v/2.1.318)

You can now move a session on your computer into a new cloud session. Claude Code copies the newest turns after checking the move is safe. A new /project command names the claude.ai Project for usage reports, and --save keeps that choice. Admins can set `disableReplyCheck` in managed settings to stop Claude being re-prompted when a turn ends without a reply. Setting `CLAUDE_CODE_ULTRAREVIEW_LAUNCH_RECORD` to a file path makes each successful ultrareview launch write its session id there. This release has 425 entries, and 240 of them are usable today.

26 entries are in the build but not switched on yet. The biggest is an experimental REPL mode, where Claude writes JavaScript that calls its tools. It comes with an opt-in dialog and limits on resuming and moving sessions. More pieces of a code-running mode landed this time, including script tracking and a tool that waits while idle. A check that can skip compacting a long conversation is also here, but it stays off unless switched on remotely. Session-long "always allow" choices for MCP connector tools, which link Claude to outside services, are recorded only when a remote switch is on.

Some of this release's fixes make broken config files safer to deal with. If the config file is corrupt or empty, Claude Code looks for the best backup and tells you what it did. A global config file that cannot be read is now left alone instead of being overwritten. A failed message send in a remote session no longer leaves it stuck sending. Cloud sessions that fail during setup now wait for the refusal message, so you can see why the launch failed. Saving over a file mounted into a container now works when the file is busy.
