[MERGED across 2 sources: github_releases, pages] shared signal: claude-code --- github_releases :: anthropics/claude-code --- anthropics/claude-code release: v2.1.210 name: v2.1.210 published: 2026-07-14T23:45:25Z url: https://github.com/anthropics/claude-code/releases/tag/v2.1.210 ## What's changed - Added a live elapsed-time counter to the collapsed tool summary line so long-running tool calls visibly tick instead of looking stuck - Added a startup warning for `Write(path)`, `NotebookEdit(path)`, and `Glob(path)` permission rules — use `Edit(path)` or `Read(path)` instead - Fixed `isolation: 'worktree'` subagents being able to run git-mutating commands against the main repo checkout instead of their own isolated worktree - Fixed the `ultracode` keyword opt-in firing on non-human-originated input such as webhook payloads and relayed PR comments - Fixed a rendered text fragment leaking into crash telemetry when a UI component returned content outside a styled text element - Fixed paste markers leaking into external editors opened from Claude Code, which could appear as stray È/É characters around pasted text - Fixed `claude attach` sometimes failing with "job not found" or "agent is still starting" errors during session transitions — attach now waits for the daemon to settle, and terminal resizes during a slow attach are applied once it completes - Fixed a session crash when a tool's result renderer returned a numeric bigint value or plain text instead of a UI element - Fixed a hook callback timeout being misreported to the model as a user rejection, which made unattended sessions stop and wait - Fixed Claude assuming a `cd` took effect after its command was moved to the background; the tool result now states the working directory is unchanged - Fixed plugin-provided MCP servers being torn down when MCP servers are re-synced mid-session - Fixed plan approvals without edits being labeled "(edited by user)" and overwriting the plan file with a stale snapshot - Fix
