Claude Code 2.1.275 adds send-now and account skill sync

Claude Code 2.1.275 landed September 17, 2026 — the same day as 2.1.274 — and the change you will actually use is how you interrupt a long turn.

Send-now is Ctrl+Enter, or Ctrl+X then Ctrl+S. It stops the current turn and flushes every queued message at once. Sent and queued text stays gray until the model receives it. If you have been stacking course-corrections while Claude is still working, this is the dump: cut in, send the queue, keep going.

Terminal sessions signed in with a claude.ai account now sync the skills and plugins enabled on that account. Opt out with syncClaudeAiSkills: false or syncClaudeAiPlugins: false. Write and Edit results on files in the synced account-skills folder now say the change is not saved to your account, and how to save it. The ListPlugins tool description was tightened so Claude knows it lists plugins enabled on the account, not plugins installed locally with /plugin.

Plugin install picked up a small workflow bump: /plugin install <plugin> --marketplace <source> offers to add the marketplace before installing.

In VS Code, the proposed-change diff tab now has accept and reject buttons under each change, so you can review an edit hunk by hunk. The same build lets you view, edit, and delete a saved memory inside the Memory dialog, and send an attached image without typing any text.

The 2.1.275 notes also fix a terminal API Error: 400 on every turn for users behind a network gateway that rewrites API error responses when a beta request header is rejected. If you sit behind a rewriting proxy, check that line after you upgrade.

Run claude --version, then try send-now on a live turn. If you sign in with claude.ai, confirm which skills and plugins landed — or set the two sync flags to false. Read the 2.1.275 release notes for the VS Code per-change buttons and the rest of the fix list.
