feature patch

Anthropic has released an update for Claude Code, version v2.1.275, introducing new capabilities and addressing numerous issues. Key additions include a "send-now" key to interrupt and send queued messages, syncing of skills and plugins from claude.ai accounts, and enhanced plugin installation options. The update also brings significant bug fixes, improving stability, memory handling, and the overall user experience across terminal, VS Code, and cloud-based sessions. These changes aim to boost developer productivity and streamline interaction with Claude's coding assistant.

  • →Added a startup warning when a configured otelHeadersHelper fails, so sessions that silently export no telemetry are noticed
  • →Added /plugin install <plugin> --marketplace <source>, which offers to add the marketplace before installing the plugin
  • →Fixed a restored memory file's age note changing between requests after a compaction or resume, which caused prompt cache misses
  • →Fixed @-mention file suggestions being buried below MCP resources when using a custom fileSuggestion command or typing @./@./
  • →Fixed a resumed cloud session leaving an unanswered question open in the transcript after a queued message superseded it
Features (5) ›

  • Added the signed-in account to Claude apps gateway sign-in: when the gateway names it, you confirm it before the credential is saved, and /status shows it

  • Added a send-now key (ctrl+enter, or ctrl+x ctrl+s) that interrupts the current turn and sends all queued messages at once; sent and queued messages show in gray until the model receives them

  • Added a startup warning when a configured otelHeadersHelper fails, so sessions that silently export no telemetry are noticed

  • Added syncing of the skills and plugins enabled on your claude.ai account to terminal sessions signed in with it; opt out with syncClaudeAiSkills: false or syncClaudeAiPlugins: false

  • Added /plugin install <plugin> --marketplace <source>, which offers to add the marketplace before installing the plugin
Enhancements (16) ›

  • Improved prompt caching for a --system-prompt that contains a __SYSTEM_PROMPT_DYNAMIC_BOUNDARY__ line: the text above it is now cached globally, as the SDK's array form already is

  • Improved the /desktop error when Claude Desktop does not open: it now says why and what to do next
  • Improved the Artifact tool's publish and read results: they now say who can open the page and what the owner's Share menu offers

  • Improved artifact publish results: they name the tab icon sent, warn when the page contains a NUL byte, and retry a flaky fetch of the newer page to merge after a stale publish

  • Improved pasted and attached images: they are now saved where Claude can open them as files without a permission prompt, including in Desktop and VS Code

  • Improved the Artifact tool's guidance so Claude updates a shared artifact in place when you were given edit access to it, instead of publishing a separate copy

  • Improved plan-usage reads: editor windows and non-interactive sessions on one machine now share a read made in the last minute instead of each calling the usage endpoint

  • Improved the ListPlugins tool description so Claude knows it lists plugins enabled on your claude.ai account, not plugins installed locally with /plugin

  • Improved responsiveness when the terminal is slow or paused: output no longer falls further behind while the terminal catches up

  • Improved Write and Edit results for files in the synced account-skills folder: they now say the change is not saved to your account and how to save it

  • Updated /logout for Claude apps gateway sign-ins to also end the session on gateways that advertise token revocation
  • Changed hosted sessions to keep an unanswered permission prompt up after a container restart, instead of asking again
  • Changed the Artifact tool to ask for a one-word tab icon on a first publish instead of an emoji favicon

  • Changed Claude in Chrome in auto mode to skip the extension's per-site check for classifier-approved calls, as bypass mode does, fixing browser_batch "Permission denied" after a redirect

  • Changed plugins installed from an npm source to be fetched with npm pack --ignore-scripts and integrity-verified, so a package's install scripts no longer run

  • Changed scheduled and Run now routine runs to save data to, and republish the page of, an artifact you can edit without asking; public artifacts, first publishes and deletes still ask

Fixes (31) ›
  • Fixed a restored memory file's age note changing between requests after a compaction or resume, which caused prompt cache misses

  • Fixed --forward-subagent-text stream-json and SDK output dropping the messages of subagents spawned by a context: fork skill, and of forked skills invoked by a subagent or another forked skill

  • Fixed @-mention file suggestions being buried below MCP resources when using a custom fileSuggestion command or typing @./@./

  • Fixed fullscreen mode placing background-task completion notices beneath a long turn's collapsed tool row instead of where they arrived; each notice now closes the open row

  • Fixed claude plugin marketplace update deleting a GitHub marketplace's local copy when the fetch failed and the marketplace was named after its repository

  • Fixed plugin and marketplace messages, logs and claude plugin marketplace list showing a password or token stored in a git, ssh or marketplace URL

  • Fixed a resumed cloud session leaving an unanswered question open in the transcript after a queued message superseded it

  • Fixed vim mode placing the cursor one character right after a dot-repeated "!" or a fast-typed "i!" switched a non-empty prompt into shell mode

  • Fixed fullscreen mode freezing or blanking for several seconds when scrolling up past a large file diff
  • Fixed a stray </ccmemory>-style closing tag occasionally appearing in responses
  • Fixed plugin messages, logs and the VS Code plugin dialog showing the wrong server for some git addresses

  • Fixed 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

  • Fixed sandboxed Bash commands on Linux reporting exit code 0 for failed commands when the shell is zsh
  • Fixed the Read tool hanging instead of reporting an error when part of a large file could not be decoded under memory pressure

  • Fixed --resume, the resume picker preview, resumed background agents and the transcript view failing on a session whose saved history contains a malformed task-reminder or @-file attachment entry

  • Fixed a crash when resuming a conversation whose transcript contains a malformed message entry, and a fullscreen crash when such a conversation received new messages while scrolled up

  • Fixed sessions failing to resume or start when their saved transcript contains a malformed message content block

  • Fixed Grep, Glob and @-file suggestions hanging or running out of memory on searches over the 20MB output cap, and system ripgrep reporting "no matches" instead of an error after a flood of warnings

  • Fixed /rewind in a forked or background session restoring a zero-filled or truncated file when the session's file-history backups could not be fully copied

  • Fixed fullscreen sessions sometimes exiting with "Claude Code exited after an unrecoverable interface error" when typing fast or holding a key with the slash-command dropdown open

  • Fixed background sessions crashing and restarting their worker when a command fed through stdin ran on a machine that had run out of file descriptors

  • Fixed a crash at launch when ~/.claude.json holds a malformed mcpNeedsAuthNoticed value

  • Fixed --resume and --continue dropping a conversation's earlier thinking when a built-in tool it started with has since been switched off by a server-side flag

  • Fixed text selected with the mouse in the fullscreen claude --resume session picker never reaching the clipboard

  • Fixed plugin reload previews replacing a running session's extracted plugin files when the plugin was loaded from a --plugin-dir or --plugin-url archive

  • Fixed self-hosted runners with --drain-wait-sec losing the final result of a turn that finished during a SIGTERM drain; the runner now waits briefly for the turn to be reported

  • Fixed SubagentStop hooks with a specific matcher firing for every stopping subagent whose agent type was empty
  • Fixed sandboxed Bash commands being unable to write to project directories named hooks/ or config/

  • Fixed Artifact updates failing with "File not found" after a session resumes on another machine or its scratchpad is cleared: the page's last published version is restored

  • Fixed /update-config writing Write(path) permission rules, which file permission checks don't match, instead of Edit(path) rules
  • Fixed four dead documentation URLs (Pricing, Computer Use, Skills, CLI) in the bundled claude-api skill's live-sources table
