Claude Code 2.1.77のダウンロード

- Increased default maximum output token limits for Claude Opus 4.6 to 64k tokens, and the upper bound for Opus 4.6 and Sonnet 4.6 models to 128k tokens
- Added allowRead sandbox filesystem setting to re-allow read access within denyRead regions
- /copy now accepts an optional index: /copy N copies the Nth-latest assistant response
- Fixed "Always Allow" on compound bash commands (e.g. cd src && npm test) saving a single rule for the full string instead of per-subcommand, leading to dead rules and repeated permission prompts
- Fixed auto-updater starting overlapping binary downloads when the slash-command overlay repeatedly opened and closed, accumulating tens of gigabytes of memory
- Fixed --resume silently truncating recent conversation history due to a race between memory-extraction writes and the main transcript
- Fixed PreToolUse hooks returning "allow" bypassing deny permission rules, including enterprise managed settings
- Fixed Write tool silently converting line endings when overwriting CRLF files or creating files in CRLF directories
- Fixed memory growth in long-running sessions from progress messages surviving compaction
- Fixed cost and token usage not being tracked when the API falls back to non-streaming mode
- Fixed CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS not stripping beta tool-schema fields, causing proxy gateways to reject requests
- Fixed Bash tool reporting errors for successful commands when the system temp directory path contains spaces
- Fixed paste being lost when typing immediately after pasting
- Fixed Ctrl+D in /feedback text input deleting forward instead of the second press exiting the session
- Fixed API error when dragging a 0-byte image file into the prompt
- Fixed Claude Desktop sessions incorrectly using the terminal CLI's configured API key instead of OAuth
- Fixed git-subdir plugins at different subdirectories of the same monorepo commit colliding in the plugin cache
- Fixed ordered list numbers not rendering in terminal UI
- Fixed a race condition where stale-worktree cleanup could delete an agent worktree just resumed from a previous crash
- Fixed input deadlock when opening /mcp or similar dialogs while the agent is running
- Fixed Backspace and Delete keys not working in vim NORMAL mode
- Fixed status line not updating when vim mode is toggled on or off
- Fixed hyperlinks opening twice on Cmd+click in VS Code, Cursor, and other xterm.js-based terminals
- Fixed background colors rendering as terminal-default inside tmux with default configuration
- Fixed iTerm2 session crash when selecting text inside tmux over SSH
- Fixed clipboard copy silently failing in tmux sessions; copy toast now indicates whether to paste with ⌘V or tmux prefix+]
- Fixed ←/→ accidentally switching tabs in settings, permissions, and sandbox dialogs while navigating lists
- Fixed IDE integration not auto-connecting when Claude Code is launched inside tmux or screen
- Fixed CJK characters visually bleeding into adjacent UI elements when clipped at the right edge
- Fixed teammate panes not closing when the leader exits
- Fixed iTerm2 auto mode not detecting iTerm2 for native split-pane teammates
- Faster startup on macOS (~60ms) by reading keychain credentials in parallel with module loading
- Faster --resume on fork-heavy and very large sessions — up to 45% faster loading and ~100-150MB less peak memory
- Improved Esc to abort in-flight non-streaming API requests
- Improved claude plugin validate to check skill, agent, and command frontmatter plus hooks/hooks.json, catching YAML parse errors and schema violations
- Background bash tasks are now killed if output exceeds 5GB, preventing runaway processes from filling disk
- Sessions are now auto-named from plan content when you accept a plan
- Improved headless mode plugin installation to compose correctly with CLAUDE_CODE_PLUGIN_SEED_DIR
- Show a notice when apiKeyHelper takes longer than 10s, preventing it from blocking the main loop
- The Agent tool no longer accepts a resume parameter — use SendMessage({to: agentId}) to continue a previously spawned agent
- SendMessage now auto-resumes stopped agents in the background instead of returning an error
- Renamed /fork to /branch (/fork still works as an alias)
- [VSCode] Improved plan preview tab titles to use the plan's heading instead of "Claude's Plan"
- [VSCode] When option+click doesn't trigger native selection on macOS, the footer now points to the macOptionClickForcesSelection setting
