Claude Code
  • Security: Bash(find:*) allow rules no longer auto-approve -exec or -delete. Expect new permission prompts if you have broad find allow rules that previously greenlit destructive flags.

  • Bash deny rules now catch commands wrapped in env, sudo, watch, setsid, and similar exec wrappers. A command you previously denied can no longer be bypassed by prepending an exec wrapper. (more below)

  • Agent frontmatter hooks: now fires when running as a main-thread agent via --agent. If you declared hooks in agent YAML for --agent invocations, they are now active where they were previously ignored. (more below)

  • The CLI spawns a native platform binary instead of bundled JavaScript (2.1.113). No action needed, but cold-start time and memory profile will differ from the Node.js bundle.

New in 2.1.116, 2.1.114, 2.1.113

2.1.116 (April 21, 2026)

  • /resume on large sessions is significantly faster (up to 67% on 40MB+ sessions) and handles sessions with many dead-fork entries more efficiently
  • Faster MCP startup when multiple stdio servers are configured; resources/templates/list is now deferred to first @-mention
  • Smoother fullscreen scrolling in VS Code, Cursor, and Windsurf terminals; /terminal-setup now configures the editor's scroll sensitivity
  • Thinking spinner now shows progress inline ("still thinking", "thinking more", "almost done thinking"), replacing the separate hint row
  • /config search now matches option values (e.g. searching "vim" finds the Editor mode setting)
  • /doctor can now be opened while Claude is responding, without waiting for the current turn to finish
  • /reload-plugins and background plugin auto-update now auto-install missing plugin dependencies from marketplaces you've already added
  • Bash tool now surfaces a hint when gh commands hit GitHub's API rate limit, so agents can back off instead of retrying
  • The Usage tab in Settings now shows your 5-hour and weekly usage immediately and no longer fails when the usage endpoint is rate-limited
  • Agent frontmatter hooks: now fire when running as a main-thread agent via --agent
  • Slash command menu now shows "No commands match" when your filter has zero results, instead of disappearing
  • Security: sandbox auto-allow no longer bypasses the dangerous-path safety check for rm/rmdir targeting /, $HOME, or other critical system directories
  • Fixed Devanagari and other Indic scripts rendering with broken column alignment in the terminal UI
  • Fixed Ctrl+- not triggering undo in terminals using the Kitty keyboard protocol (iTerm2, Ghostty, kitty, WezTerm, Windows Terminal)
  • Fixed Cmd+Left/Right not jumping to line start/end in terminals that use the Kitty keyboard protocol (Warp fullscreen, kitty, Ghostty, WezTerm)
  • Fixed Ctrl+Z hanging the terminal when Claude Code is launched via a wrapper process (e.g. npx, bun run)
  • Fixed scrollback duplication in inline mode where resizing the terminal or large output bursts would repeat earlier conversation history
  • Fixed modal search dialogs overflowing the screen at short terminal heights, hiding the search box and keyboard hints
  • Fixed scattered blank cells and disappearing composer chrome in the VS Code integrated terminal during scrolling
  • Fixed an intermittent API 400 error related to cache control TTL ordering that could occur when a parallel request completed during request setup
  • Fixed /branch rejecting conversations with transcripts larger than 50MB
  • Fixed /resume silently showing an empty conversation on large session files instead of reporting the load error
  • Fixed /plugin Installed tab showing the same item twice when it appears under Needs attention or Favorites
  • Fixed /update and /tui not working after entering a worktree mid-session

2.1.114 (April 21, 2026)

  • Fixed a crash in the permission dialog when an agent teams teammate requested tool permission

2.1.113 (April 21, 2026)

  • Changed the CLI to spawn a native Claude Code binary (via a per-platform optional dependency) instead of bundled JavaScript
  • Added sandbox.network.deniedDomains setting to block specific domains even when a broader allowedDomains wildcard would otherwise permit them
  • Fullscreen mode: Shift+Up/Down now scrolls the viewport when extending a selection past the visible edge
  • Ctrl+A and Ctrl+E now move to the start/end of the current logical line in multiline input, matching readline behavior
  • Windows: Ctrl+Backspace now deletes the previous word
  • Long URLs in responses and bash output stay clickable when they wrap across lines (in terminals with OSC 8 hyperlinks)
  • Improved /loop: pressing Esc now cancels pending wakeups, and wakeups display as "Claude resuming /loop wakeup" for clarity
  • /extra-usage now works from Remote Control (mobile/web) clients
  • Remote Control clients can now query @-file autocomplete suggestions
  • Improved /ultrareview: faster launch with parallelized checks, diffstat in the launch dialog, and animated launching state
  • Subagents that stall mid-stream now fail with a clear error after 10 minutes instead of hanging silently
  • Bash tool: multi-line commands whose first line is a comment now show the full command in the transcript, closing a UI-spoofing vector
  • Running cd <current-directory> && git ... no longer triggers a permission prompt when the cd is a no-op
  • Security: on macOS, /private/{etc,var,tmp,home} paths are now treated as dangerous removal targets under Bash(rm:*) allow rules
  • Security: Bash deny rules now match commands wrapped in env/sudo/watch/ionice/setsid and similar exec wrappers
  • Security: Bash(find:*) allow rules no longer auto-approve find -exec/-delete
  • Fixed MCP concurrent-call timeout handling where a message for one tool call could silently disarm another call's watchdog
  • Fixed Cmd-backspace / Ctrl+U to once again delete from the cursor to the start of the line
  • Fixed markdown tables breaking when a cell contains an inline code span with a pipe character
  • Fixed session recap auto-firing while composing unsent text in the prompt
  • Fixed /copy "Full response" not aligning markdown table columns for pasting into GitHub, Notion, or Slack
  • Fixed messages typed while viewing a running subagent being hidden from its transcript and misattributed to the parent AI
  • Fixed Bash dangerouslyDisableSandbox running commands outside the sandbox without a permission prompt
  • Fixed /effort auto confirmation now says "Effort level set to max" to match the status bar label
  • Fixed the "copied N chars" toast overcounting emoji and other multi-code-unit characters
  • Fixed /insights crashing with EBUSY on Windows
  • Fixed exit confirmation dialog mislabeling one-shot scheduled tasks as recurring, now shows a countdown
  • Fixed slash/@ completion menu not sitting flush against the prompt border in fullscreen mode
  • Fixed CLAUDE_CODE_EXTRA_BODY output_config.effort causing 400 errors on subagent calls to models that don't support effort and on Vertex AI
  • Fixed prompt cursor disappearing when NO_COLOR is set
  • Fixed ToolSearch ranking so pasted MCP tool names surface the actual tool instead of description-matching siblings
  • Fixed compacting a resumed long-context session failing with "Extra usage is required for long context requests"
  • Fixed plugin install succeeding when a dependency version conflicts with an already-installed plugin, now reports range-conflict
  • Fixed "Refine with Ultraplan" not showing the remote session URL in the transcript
  • Fixed SDK image content blocks that fail to process crashing the session, now degrade to a text placeholder
  • Fixed Remote Control sessions not streaming subagent transcripts
  • Fixed Remote Control sessions not being archived when Claude Code exits
  • Fixed thinking.type.enabled is not supported 400 error when using Opus 4.7 via a Bedrock Application Inference Profile ARN

Notes

The security sandbox is catching more evasion patterns now. 2.1.113 closes three distinct bypass vectors in one release: exec-wrapper evasion (deny rules ignored sudo/env prefixes), destructive find flags sailing through broad find:* allows, and macOS symlink paths (/private/etc) dodging dangerous-path checks. Combined with 2.1.116's fix for sandbox auto-allow bypassing the rm/rmdir safety check, this is a concerted hardening pass. If you maintain custom allow/deny rules, audit them against these new behaviors.

Agent hooks reaching --agent completes the hooks surface area. 2.1.105 introduced PreCompact hooks and background plugin monitors. 2.1.108 made the model able to invoke built-in slash commands via the Skill tool. Now 2.1.116 ensures that hooks declared in agent frontmatter actually fire when the agent runs as a main thread (via --agent). If you have agents with hooks: blocks that you launch with --agent, those hooks were silently dropped before today. They are now live.
