Admins for Team and Enterprise plans can now require members to verify their device before viewing or steering local Claude Code sessions remotely. For more information, see Trusted Devices.
Team and Enterprise plans can now tag Claude directly in Slack conversations and delegate tasks to it while they focus on other work. For more information, see our blog post: Introducing Claude Tag.
We launched Claude Fable 5, a Mythos-class model that we’ve made safe for general use. For more information, see our blog post: Claude Fable 5 and Claude Mythos 5.
Added CLAUDE_CODE_DISABLE_MOUSE_CLICKS to disable mouse click/drag/hover in fullscreen mode while keeping wheel scroll
Fixed hook matchers with hyphenated identifiers (e.g. code-reviewer, mcp__brave-search) accidentally substring-matching — they now exact-match. Use mcp__brave-search__.* to match all tools from a hyphenated MCP server.
Fixed voice dictation on macOS capturing silence in long-running sessions after the default input device changes
...
Added autoMode.classifyAllShell setting to route all Bash/PowerShell commands through the auto-mode classifier instead of only arbitrary-code-execution patterns
Added auto-mode denial reasons to the transcript, the denial toast, and /permissions recent denials
Added claude_code.assistant_response OpenTelemetry log event containing the model's response text. Redacted unless OTEL_LOG_ASSISTANT_RESPONSES=1; when that var is unset it follows OTEL_LOG_USER_PROMPTS, so deployments that...
Added sandbox.credentials setting to block sandboxed commands from reading credential files and secret environment variables
Added org-configured model restrictions to the model picker, --model, /model, and ANTHROPIC_MODEL, with a "restricted by your organization's settings" message when a restricted model is selected
Added mouse click support to select menus (permission prompts, /model, /config, etc.) in fullscreen mode
...
Added claude mcp login and claude mcp logout to authenticate MCP servers from the CLI without opening the interactive /mcp menu, with --no-browser stdin redirect support for completing over SSH
Added status filtering (press f) to the /workflows agent detail view
Added a "Skills" section to the /plugin Installed tab
Added teammateMode: "iterm2" setting with a warning when auto mode cannot find the it2 CLI

We've raised rate limits across the Claude API. Claude Sonnet and Claude Haiku rate limits now match Claude Opus at every usage tier, and usage tiers have been consolidated into three: Start, Build, and Scale. Most organizations move to a higher tier, no organization receives lower limits than before, and no action is required. You can view your tier and current limits in the Claude Console.
We've deprecated fast mode for Claude Opus 4.7, with removal on July 24, 2026. After removal, requests to claude-opus-4-7 with speed: "fast" will return an error. Migrate to fast mode for Claude Opus 4.8. Read more in Fast mode.
The Python, TypeScript, Go, Java, Ruby, PHP, and C# SDKs now include support for code_execution_20260120, the code execution tool version that adds REPL state persistence and is the minimum version for programmatic tool calling. To adopt it, set the tool's type to code_execution_20260120; no beta header is required....
The code execution tool now supports code_execution_20260521, which discloses the 90-second per-cell execution time limit in the tool description so Claude can budget long-running cells. No beta header is required.

We've retired the Claude Sonnet 4 model (claude-sonnet-4-20250514) and the Claude Opus 4 model (claude-opus-4-20250514). All requests to these models will now return an error. We recommend upgrading to Claude Sonnet 4.6 and Claude Opus 4.8 respectively. Researchers can request ongoing access through the [External...
