 # Changelog
 
+## 2.1.216
+
+- Added `sandbox.filesystem.disabled` setting to skip filesystem isolation while keeping network egress control
+- Fixed a slowdown in long sessions where message normalization cost grew quadratically with the number of turns, causing multi-second stalls and slow resumes
+- Fixed auto mode denying commands with "HTTP 401" classifier errors after the OAuth token expired or rotated mid-session
+- Fixed AskUserQuestion telling Claude to continue even when your answer asked it to wait or explain first — free-text answers now get neutral wording
+- Fixed Claude Code on the web re-asking the same question and dropping your answer after the session sat idle for a few minutes
+- Fixed @-mentions silently attaching nothing after file-modifying hooks, vim dot-repeat of `c`-operators and paste, statusline running twice on resume, and resume-picker hangs on failure
+- Fixed resumed background agent sessions reverting to the default agent: the agent's prompt and tool restrictions are now restored
+- Fixed worktree-isolated subagents redirecting git into the shared checkout via `git -C`, `--git-dir`, or `GIT_DIR`/`GIT_WORK_TREE`
+- Fixed worktree sessions landing in another project's leftover worktree when the working directory did not match the selected project
+- Fixed background sessions whose worktree has no git repository being undeletable
+- Fixed `claude daemon stop --any` potentially terminating an unrelated process via a stale legacy daemon lockfile
+- Fixed Esc-Esc at an idle prompt not opening the rewind picker in long-running sessions with background tasks
+- Fixed Bash command permission checking for compound statements with redirects inside `&&` lists or negations
+- Fixed pressing Ctrl+X twice in the agent list failing to delete a session, and deleted sessions reappearing when their background worker had died
+- Fixed background subagents getting cancelled when a high-priority message arrives during their startup window
+- Fixed mouse and focus garbage in the terminal while a GUI editor from `/memory`, `/plan`, `/keybindings`, or Ctrl+G is open; `/memory` no longer waits for the editor to close
+- Fixed Claude-in-Chrome 403-looping on reconnect when the session's OAuth token lacks a required scope
+- Fixed workflow saves and scheduled-task writes following a symlink at `.claude`, which could redirect writes outside the project
+- Fixed MCP re-authenticate revoking working credentials before the new sign-in succeeds, and the reconnect needs-auth message in background sessions pointing at an unusable command
+- Fixed read-only commands on Windows accessing network paths without a permission prompt
+- Fixed Bash command parsing of non-ASCII characters to match real shell word boundaries
+- Fixed PowerShell tool permission validation of commands containing invisible Unicode characters
+- Fixed dialogs in fullscreen mode stretching past the right-hand edge of their panel
+- Fixed the `/config` settings list in fullscreen mode clipping its keyboard-hint footer
+- Fixed the transcript-mode (Ctrl+O) footer hint wrapping on terminals narrower than 104 columns
+- Fixed the Prometheus metrics endpoint (`OTEL_METRICS_EXPORTER=prometheus`) emitting invalid `# UNIT` lines
+- Fixed skills and commands changed during a session not appearing in the slash menu until restart
+- Fixed plugin skills with a `name` frontmatter field losing their plugin prefix in slash-command autocomplete
+- Fixed telemetry misreporting permission denials: failed permission-prompt requests no longer count as user rejections, and user interrupts are now reported as user aborts instead of rejections
+- Improved the `/fork` confirmation to one line with the new session's name, `claude attach` id, and a note when the copy shares your checkout
+- Improved validation of `git` and `gh` command arguments in the PowerShell tool
+- Improved the `/ultrareview` diff-too-large error to show configured limits, measured diff size, and largest contributing files
+- Improved `/code-review ultra` empty-diff message to name the exact base ref and suggest passing an explicit base
+- Improved the spend limit adjustment prompt to show the server's reason when a spend limit change is rejected
+- `/context` now shows an explicit warning when the conversation exceeds the context window, and a failed `/compact` displays as an error
+- `/rewind` no longer restores or deletes files through symlinks or hard links at tracked paths and reports how many paths it skipped
+- Background sessions: `/mcp` and `/install-github-app` now park a "needs input" request in the agent view when no client is attached
+- Updated the bundled dataviz skill: reordered the default chart palette and fixed guidance that suggested direct labels for four-series charts
+- [VSCode] Fixed right-to-left text (Arabic, Hebrew, Persian) rendering in the wrong order when mixed with English or code
+- Fixed cloud sessions dropping the in-flight message when the session's container restarts mid-turn — the interrupted turn now re-runs on resume instead of leaving the session unresponsive
+
 ## 2.1.215
 
 - Claude no longer runs the `/verify` and `/code-review` skills on its own; invoke them with `/verify` or `/code-review` when you want them
