# Claude Code v2.1.305

> Claude Code v2.1.305, released 20 Oct 2026 (2026-10-20). 252 entries read out of the shipped bundle. Unofficial, and not affiliated with Anthropic.

[Web version](https://changelogs.core-directive.com/v/2.1.305)

Claude can now upload a local file to Google Drive by naming it, up to 10 MB. Claude Code reads the file only after you approve the call. In remote sessions that support it, you can now run '!' shell commands, with a 10 minute timeout. Sonnet 4, Sonnet 4.6 and Opus 4.6 now list a 1 million token maximum context window. `claude plugin validate` now also checks a plugin's folder layout. A new environment variable, `CLAUDE_CODE_CCR_EVENT_FLUSH_POLICY`, sets how a remote session sends out its events.

Several features are in this build but not switched on yet. /usage is getting a way to look through your recent sessions and suggest how to use less of your plan. It could then queue the fixes you pick, such as `/compact` or lower effort, as prompts. Groundwork is also present for `--resume` to pick up a cloud session. Cloud sessions may later check each MCP server's host against an allow or deny list. While waiting on a usage limit, Claude Code could send a test request to see whether the limit has lifted.

Shell commands sent to a session for one folder are now refused if the session is working in a different folder. Disallowed tools now stay blocked while a leftover permission request is handled. Team memory changes held back by a sync pause are now kept and retried instead of dropped. The hint to raise `API_TIMEOUT_MS` after a timeout now notices a value set in your settings. Worktrees made from origin's default branch now use the exact remote branch. The message saying auto mode works only inside the sandbox has been removed.
