Released October 1, 2026

Key changes

• Added Claude Mods: plugins may now modify deeper behavior
• Added You should know, a built-in mod where a side agent watches your back and flags things you or Claude might miss. Turn it on with /plugin enable cc-plugin-you-should-know@builtin (for first-party sessions with…
• Added an n:<text> filter to the agents view that matches session names and tasks; a filter now shows matches in collapsed sections and Enter opens the first match
• Added prompttext to the OpenTelemetry userprompt event, a copy of prompt for backends that nest dotted keys; drop or mask it wherever you drop or mask prompt (anthropics/claude-code#70763)
• Added URL prompts from MCP servers on the 2025-11-25 protocol, for example to sign in. If a server no longer connects after this update, add "bareElicitationCapability": true to its MCP config entry
• [VSCode] Added "Run in background" to a running command or sub-agent, to move it to the background and keep working

Recent releases

• v2.1.286 · September 30, 2026

  Added a count such as "2 of 5" to the permission prompt when several permission requests stack up

  Added mouse support for the "N more" rows of lists in fullscreen mode: click one to jump to that end of the list, with hover and pressed states

  [VSCode] Added bookmarks: save Claude's responses and keep them in view in a Bookmarks side panel

• v2.1.285 · September 29, 2026

  Added CLAUDECODEDISABLEWEBFETCH environment variable to turn off the WebFetch tool

  Added claude --desktop to open the Claude desktop app on the current directory, or on a session with --continue / --resume <id>

  Added claude plugin configure <plugin> to show a plugin's options and which are unset, or save new values read from stdin with --values-stdin

• v2.1.284 · September 28, 2026

  Added Claude Sonnet 5.5 (claude-sonnet-5-5), now the default Sonnet model on the Anthropic API — 1M context, $2/$10 per Mtok with $0.20/Mtok cache reads

  Added a "Yes, but ask again next time" answer to auto mode's prompt before a read outside the working directories, so you can allow that one read and still be asked about later ones

  Added dollar amounts to the Claude apps gateway spend limit in /usage and the status line (for example "$271.40 / $500.00 spent this month") when the gateway runs this version or later; the status line's…

• v2.1.283 · September 25, 2026

  Added x-claude-code-prompt-id to the gateway hint headers so LLM gateways can group the requests that serve one user prompt; opt in with CLAUDECODEGATEWAYHINTHEADERS=1

  Added availableModelsMatch managed setting: with "exact", an availableModels entry allows only the model version it names, so new releases stay blocked until listed

  Added deniedModels managed setting to block specific models, even when availableModels allows them
