What's new in Claude

Added CLAUDE_CODE_DISABLE_MOUSE_CLICKS env var to disable mouse interactions in fullscreen mode while preserving wheel scroll. Also fixed hook matchers with hyphenated identifiers, voice dictation on macOS, and background agent daemons failing to start the control socket.

Added autoMode.classifyAllShell to route all Bash/PowerShell commands through the auto-mode classifier, with denial reasons surfaced in transcripts and /permissions. Added live file path autocomplete in bash mode (!). Added background shell memory management with automatic pressure-based reaping.

Added /rewind support to resume conversations from before /clear was run. Fixed scroll position jumping during streaming responses. Fixed background agents resurrecting after being stopped. Fixed /voice not explaining organization policy restrictions.

claude mcp login / logout — authenticate a configured MCP server from your shell without going through the interactive /mcp menu; clear stored credentials later with claude mcp logout.

Shell mode responds to command output — ! npm test now gets an explanation of the failures without a second prompt. Set respondToBashCommands: false in settings to revert.

/rewind after /clear — resume a conversation from before you cleared it; Claude reloads the prior context window so nothing is truly lost.

Background subagents surface permission prompts — instead of auto-denying blocked actions, background agents now bubble up the prompt to the main session so you can approve in real time.

API rate limits raised. Claude Sonnet and Haiku rate limits now match Claude Opus at every usage tier. Tiers consolidated to three: Start, Build, and Scale — most organizations move up, none move down. No action required; check current limits in the Claude Console.

Fast mode deprecated for Claude Opus 4.7 — removal on July 24, 2026. Requests to claude-opus-4-7 with speed: "fast" will error after that date. Migrate to fast mode on Claude Opus 4.8 now.

Code execution tool across all major SDKs — Python, TypeScript, Go, Java, Ruby, PHP, and C# now support code_execution_20260120 with REPL state persistence, the minimum version for programmatic tool calling. No beta header required. Available on Fable 5, Mythos 5, Opus 4.5+, Sonnet 4.5+.

Claude Sonnet 4 and Opus 4 retired. All requests to claude-sonnet-4-20250514 and claude-opus-4-20250514 now return an error. Upgrade to Claude Sonnet 4.6 and Claude Opus 4.8 respectively.

Quiet over the weekend. Earlier this week: highlighted v2.1.195's mouse-click disable env var and the 37% CPU reduction in streaming. Also noted Claude Code weekly limits are up 50% through July 13 on Pro, Max, Team, and Enterprise plans.

Quiet today. Recent theme: Claude Fable 5 rollout, 1M context window by default, and the new three-tier API rate structure (Start / Build / Scale).

Shared a thread on Claude Code's deep customizability — hooks, plugins, LSPs, MCPs, skills, effort, custom agents, status lines, output styles — and why the team built it with great defaults rather than forcing one workflow. "Every engineer uses their tools differently." Still hasn't written a line of code himself in 2026.

Posted on dynamic workflows — "A harness for every task": Claude writes its own orchestration script on the fly, fanning out to dozens of subagents custom-built for the task. Also active on how the Anthropic team internally stays in the loop on Claude Code's fast-moving changes.
