Claude Code v1.0.116

What: Interactive command history search similar to bash's reverse-i-search

How to use:

# In the interactive prompt, press Ctrl+R
# Type your search query - matches appear from command history
# Press Ctrl+R again to cycle through matches
# Press Enter to execute, Escape/Tab to accept without executing

Details:

• Displays "bck-i-search: " prompt when active
• Shows "failing bck-i-search: " when no matches found
• Searches through full command history including pasted content
• Ctrl+C cancels and restores previous input
• Evidence: YNB() at line 429227, ZW5() at line 429311

What: Separate OAuth credential storage for local development vs production

How to use:

# Production credentials (default)
# Stored in: ~/.claude.json

# Local development credentials
export USE_LOCAL_OAUTH=1
# Stored in: ~/.claude-local-oauth.json

Details:

• Prevents accidentally overwriting production OAuth tokens during development
• Separate keychain entries: "Claude Code" vs "Claude Code-local-oauth"
• Configuration files: .claude.json (prod) or .claude-local-oauth.json (local)
• Infrastructure for staging environment included but not yet active
• Evidence: Uo1() at line 339682, KZ9() at line 339686, uJ() at line 339696

What: Remember network access decisions for the current session

How to use:

# When prompted for network access outside sandbox:
# - "Yes" - Allow once
# - "Yes, and allow accessing host:port for this session" - Remember for session
# - "No, and disable accessing host:port for this session" - Block for session

Details:

• Reduces repetitive permission prompts for trusted hosts
• Session-scoped - resets when Claude Code restarts
• Works with sandbox network restrictions
• Evidence: pNB() at line 431799, Bx6() at line 374794

What: New backend API for fetching session events and metadata

Details:

• Currently disabled by feature flag (YD1() returns false)
• Uses /v1/sessions/ endpoints instead of /api/oauth/
• Supports fetching session events for replay capability
• New data structure with session_context.sources and session_context.outcomes
• Will enable enhanced teleport functionality when activated
• Evidence: P55() at line 413749, S55() at line 413999, j55() at line 413991

What: Complete architectural overhaul of the sandboxing implementation

Key Changes:

• Centralized sandbox manager with clean API (hV object at line 374998)
• New configuration model: allowAllExcept (blacklist) vs denyAllExcept (whitelist)
• Network deny-lists alongside allow-lists for more granular control
• macOS sandbox profiles now use deny-by-default security model
• Recommended defaults for common development tools (npm, cargo, yarn, etc.)
• Dynamic permission callbacks for interactive network access control
• Evidence: wBB() at line 374755, Zx6() at line 374844, DBB() at line 374642

Migration Notes:

• Existing sandbox configurations continue to work
• New includeRecommendedDefaults option automatically allows access to common tools
• Deny-by-default macOS profiles are more secure but may require configuration updates

What: More specific error messages when model validation fails

Details:

• Distinguishes between "model not found", "authentication failed", and "network error"
• Provides actionable error messages instead of generic failures
• Better parsing of API error responses
• Evidence: yJ5() at line 436574

What: Editor detection is now memoized for better performance

Details:

• Checks VISUAL and EDITOR environment variables
• Falls back to ["code", "vi", "nano"] in order
• Result is cached to avoid repeated filesystem checks
• Evidence: Cf1 at line 404874 (previously Jf1() at line 404673 in v1.0.115)

What: Better error handling for session resume operations

Details:

• Shows "Session resumed" (info) on success
• Shows "Session resumed without branch: [error]" (warning) on partial failure
• Uses formatted error messages when available
• Evidence: bzB() at line 413552 (previously o65() at line 413908 in v1.0.115)

What: Prevents mutation of original sandbox configuration

Details:

• Uses deep clone when processing sandbox config
• Prevents unexpected side effects when adding recommended defaults
• Evidence: EBB.cloneDeep(A) at line 374849 in Zx6()

• OAuth config selector: D6() → L4()
• Config file path: bJ() → uJ()
• OAuth configs: HS9 → pPA, DS9 → gS9, fPA → iPA
• Sandbox functions: GBB() → wBB(), JBB() → Zx6(), FBB() → Ix6()
• Linux wrapper: YBB() → zBB()

• Session memory config: bd5() → cp5 object
• Session memory processor: _$3 → E_3
• Now uses agent definition pattern for consistency

• Added OAUTH_FILE_SUFFIX field to all OAuth configs
• Production: OAUTH_FILE_SUFFIX: ""
• Local: OAUTH_FILE_SUFFIX: "-local-oauth"

• The Sessions API integration is implemented but disabled by feature flag
• Sandbox recommended defaults include paths for npm, yarn, pnpm, cargo, rustup, homebrew
• Environment-specific OAuth credentials prevent common development workflow issues
• Reverse search history uses React hooks for state management in the terminal UI
