Claude Code CLI 2.1.47 changelog:
• Fixed FileWriteTool line counting to preserve intentional trailing blank lines instead of stripping them with `trimEnd()`.
• Fixed Windows terminal rendering bugs caused by `os.EOL` (`\r\n`) in display code — line counts now show correct values instead of always showing 1 on Windows.
• Improved VS Code plan preview: auto-updates as Claude iterates, enables commenting only when the plan is ready for review, and keeps the preview open when rejecting so Claude can revise.
• Fixed a bug where bold and colored text in markdown output could shift to the wrong characters on Windows due to `\r\n` line endings.
• Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (anthropics/claude-code#26188)
• Improved memory usage in long-running sessions by releasing API stream buffers, agent context, and skill state after use
• Improved startup performance by deferring SessionStart hook execution, reducing time-to-interactive by ~500ms.
• Fixed an issue where bash tool output was silently discarded on Windows when using MSYS2 or Cygwin shells.
• Improved performance of `@` file mentions - file suggestions now appear faster by pre-warming the index on startup and using session-based caching with background refresh.
• Improved memory usage by trimming agent task message history after tasks complete
• Improved memory usage during long agent sessions by eliminating O(n²) message accumulation in progress updates
• Fixed the bash permission classifier to validate that returned match descriptions correspond to actual input rules, preventing hallucinated descriptions from incorrectly granting permissions
• Fixed user-defined agents only loading one file on NFS/FUSE filesystems that report zero inodes (anthropics/claude-code#26044)
• Fixed plugin agent skills silently failing to load when referenced by bare name instead of fully-qualified plugin name (anthropics/claude-code#25834)
• Search patterns in collapsed tool results are now displayed in quotes for clarity
• Windows: Fixed CWD tracking temp files never being cleaned up, causing them to accumulate indefinitely (anthropics/claude-code#17600)
• Use `ctrl f` to kill all background agents instead of double-pressing ESC. Background agents now continue running when you press ESC to cancel the main thread, giving you more control over agent lifecycle.
• Fixed API 400 errors ("thinking blocks cannot be modified") that occurred in sessions with concurrent agents, caused by interleaved streaming content blocks preventing proper message merging.
• Simplified teammate navigation to use only Shift Down (with wrapping) instead of both Shift Up and Shift Down.
• Fixed an issue where a single file write/edit error would abort all other parallel file write/edit operations. Independent file mutations now complete even when a sibling fails.
• Added `last_assistant_message` field to Stop and SubagentStop hook inputs, providing the final assistant response text so hooks can access it without parsing transcript files.
• Fixed custom session titles set via `/rename` being lost after resuming a conversation (anthropics/claude-code#23610)
• Fixed collapsed read/search hint text overflowing on narrow terminals by truncating from the start.
• Fixed an issue where bash commands with backslash-newline continuation lines (e.g., long commands split across multiple lines with `\`) would produce spurious empty arguments, potentially breaking command execution.
• Fixed built-in slash commands (`/help`, `/model`, `/compact`, etc.) being hidden from the autocomplete dropdown when many user skills are installed (anthropics/claude-code#22020)
• Fixed MCP servers not appearing in the MCP Management Dialog after deferred loading
• Fixed session name persisting in status bar after `/clear` command (anthropics/claude-code#26082)
• Fixed crash when a skill's `name` or `description` in
SKILL.md frontmatter is a bare number (e.g., `name: 3000`) — the value is now properly coerced to a string (anthropics/claude-code#25837)
• Fixed /resume silently dropping sessions when the first message exceeds 16KB or uses array-format content (anthropics/claude-code#25721)
• Added `chat:newline` keybinding action for configurable multi-line input (anthropics/claude-code#26075)
• Added `added_dirs` to the statusline JSON `workspace` section, exposing directories added via `/add-dir` to external scripts (anthropics/claude-code#26096)
• Fixed `claude doctor` misclassifying mise and asdf-managed installations as native installs (anthropics/claude-code#26033)
• Fixed zsh heredoc failing with "read-only file system" error in sandboxed commands (anthropics/claude-code#25990)
• Fixed agent progress indicator showing inflated tool use count (anthropics/claude-code#26023)
• Fixed image pasting not working on WSL2 systems where Windows copies images as BMP format (anthropics/claude-code#25935)
• Fixed background agent results returning raw transcript data instead of the agent's final answer (anthropics/claude-code#26012)
• Fixed Warp terminal incorrectly prompting for Shift Enter setup when it supports it natively (anthropics/claude-code#25957)
• Fixed CJK wide characters causing misaligned timestamps and layout elements in the TUI (anthropics/claude-code#26084)
• Fixed custom agent `model` field in `.claude/agents/*.md` being ignored when spawning team teammates (anthropics/claude-code#26064)
• Fixed plan mode being lost after context compaction, causing the model to switch from planning to implementation mode (anthropics/claude-code#26061)
• Fixed `alwaysThinkingEnabled: true` in settings.json not enabling thinking mode on Bedrock and Vertex providers (anthropics/claude-code#26074)
• Fixed `tool_decision` OTel telemetry event not being emitted in headless/SDK mode (anthropics/claude-code#26059)
• Fixed session name being lost after context compaction — renamed sessions now preserve their custom title through compaction (anthropics/claude-code#26121)
• Increased initial session count in resume picker from 10 to 50 for faster session discovery (anthropics/claude-code#26123)
• Windows: fixed worktree session matching when drive letter casing differs (anthropics/claude-code#26123)
• Fixed `/resume <session-id>` failing to find sessions whose first message exceeds 16KB (anthropics/claude-code#25920)
• Fixed "Always allow" on multiline bash commands creating invalid permission patterns that corrupt settings (anthropics/claude-code#25909)
• Fixed React crash (error #31) when a skill's `argument-hint` in
SKILL.md frontmatter uses YAML sequence syntax (e.g., `[topic: foo | bar]`) — the value is now properly coerced to a string (anthropics/claude-code#25826)
• Fixed crash when using `/fork` on sessions that used web search — null entries in search results from transcript deserialization are now handled gracefully (anthropics/claude-code#25811)
• Fixed read-only git commands triggering FSEvents file watcher loops on macOS by adding --no-optional-locks flag (anthropics/claude-code#25750)
• Fixed custom agents and skills not being discovered when running from a git worktree — project-level `.claude/agents/` and `.claude/skills/` from the main repository are now included (anthropics/claude-code#25816)
• Fixed non-interactive subcommands like `claude doctor` and `claude plugin validate` being blocked inside nested Claude sessions (anthropics/claude-code#25803)
• Windows: Fixed the same
CLAUDE.md file being loaded twice when drive letter casing differs between paths (anthropics/claude-code#25756)
• Fixed inline code spans in markdown being incorrectly parsed as bash commands (anthropics/claude-code#25792)
• Fixed teammate spinners not respecting custom spinnerVerbs from settings (anthropics/claude-code#25748)
• Fixed shell commands permanently failing after a command deletes its own working directory (anthropics/claude-code#26136)
• Fixed hooks (PreToolUse, PostToolUse) silently failing to execute on Windows by using Git Bash instead of cmd.exe (anthropics/claude-code#25981)
• Fixed LSP `findReferences` and other location-based operations returning results from gitignored files (e.g., `node_modules/`, `venv/`) (anthropics/claude-code#26051)

• Fixed background tasks failing in git worktrees due to remote URL resolution reading from worktree-specific gitdir instead of the main repository config (anthropics/claude-code#26065)
• Fixed Right Alt key leaving visible `[25~` escape sequence residue in the input field on Windows/Git Bash terminals (anthropics/claude-code#25943)
