What's changed
- 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\nline endings. - Fixed compaction failing when conversation contains many PDF documents by stripping document blocks alongside images before sending to the compaction API (#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 (#26044)
- Fixed plugin agent skills silently failing to load when referenced by bare name instead of fully-qualified plugin name (#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 (#17600)
- Use
ctrl+fto 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_messagefield 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
/renamebeing lost after resuming a conversation (#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 (#22020) - Fixed MCP servers not appearing in the MCP Management Dialog after deferred loading
- Fixed session name persisting in status bar after
/clearcommand (#26082) - Fixed crash when a skill's
nameordescriptionin SKILL.md frontmatter is a bare number (e.g.,name: 3000) — the value is now properly coerced to a string (#25837) - Fixed /resume silently dropping sessions when the first message exceeds 16KB or uses array-format content (#25721)
- Added
chat:newlinekeybinding action for configurable multi-line input (#26075) - Added
added_dirsto the statusline JSONworkspacesection, exposing directories added via/add-dirto external scripts (#26096) - Fixed
claude doctormisclassifying mise and asdf-managed installations as native installs (#26033) - Fixed zsh heredoc failing with "read-only file system" error in sandboxed commands (#25990)
- Fixed agent progress indicator showing inflated tool use count (#26023)
- Fixed image pasting not working on WSL2 systems where Windows copies images as BMP format (#25935)
- Fixed background agent results returning raw transcript data instead of the agent's final answer (#26012)
- Fixed Warp terminal incorrectly prompting for Shift+Enter setup when it supports it natively (#25957)
- Fixed CJK wide characters causing misaligned timestamps and layout elements in the TUI (#26084)
- Fixed custom agent
modelfield in.claude/agents/*.mdbeing ignored when spawning team teammates (#26064) - Fixed plan mode being lost after context compaction, causing the model to switch from planning to implementation mode (#26061)
- Fixed
alwaysThinkingEnabled: truein settings.json not enabling thinking mode on Bedrock and Vertex providers (#26074) - Fixed
tool_decisionOTel telemetry event not being emitted in headless/SDK mode (#26059) - Fixed session name being lost after context compaction — renamed sessions now preserve their custom title through compaction (#26121)
- Increased initial session count in resume picker from 10 to 50 for faster session discovery (#26123)
- Windows: fixed worktree session matching when drive letter casing differs (#26123)
- Fixed
/resume <session-id>failing to find sessions whose first message exceeds 16KB (#25920) - Fixed "Always allow" on multiline bash commands creating invalid permission patterns that corrupt settings (#25909)
- Fixed React crash (error #31) when a skill's
argument-hintin SKILL.md frontmatter uses YAML sequence syntax (e.g.,[topic: foo | bar]) — the value is now properly coerced to a string (#25826) - Fixed crash when using
/forkon sessions that used web search — null entries in search results from transcript deserialization are now handled gracefully (#25811) - Fixed read-only git commands triggering FSEvents file watcher loops on macOS by adding --no-optional-locks flag (#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 (#25816) - Fixed non-interactive subcommands like
claude doctorandclaude plugin validatebeing blocked inside nested Claude sessions (#25803) - Windows: Fixed the same CLAUDE.md file being loaded twice when drive letter casing differs between paths (#25756)
- Fixed inline code spans in markdown being incorrectly parsed as bash commands (#25792)
- Fixed teammate spinners not respecting custom spinnerVerbs from settings (#25748)
- Fixed shell commands permanently failing after a command deletes its own working directory (#26136)
- Fixed hooks (PreToolUse, PostToolUse) silently failing to execute on Windows by using Git Bash instead of cmd.exe (#25981)
- Fixed LSP
findReferencesand other location-based operations returning results from gitignored files (e.g.,node_modules/,venv/) (#26051) - Moved config backup files from home directory root to
~/.claude/backups/to reduce home directory clutter (#26130) - Fixed sessions with large first prompts (>16KB) disappearing from the /resume list (#26140)
- Fixed shell functions with double-underscore prefixes (e.g.,
__git_ps1) not being preserved across shell sessions (#25824) - Fixed spinner showing "0 tokens" counter before any tokens have been received (#26105)
- VSCode: Fixed conversation messages appearing dimmed while the AskUserQuestion dialog is open (#26078)
- Fixed background tasks failing in git worktrees due to remote URL resolution reading from worktree-specific gitdir instead of the main repository config (#26065)
- Fixed Right Alt key leaving visible
[25~escape sequence residue in the input field on Windows/Git Bash terminals (#25943) - The
/renamecommand now updates the terminal tab title by default (#25789) - Fixed Edit tool silently corrupting Unicode curly quotes (\u201c\u201d \u2018\u2019) by replacing them with straight quotes when making edits (#26141)
- Fixed OSC 8 hyperlinks only being clickable on the first line when link text wraps across multiple terminal lines.
