Claude Code v1.0.93

What: Network isolation now available on Linux using bubblewrap (bwrap) How to use:

# Network sandboxing automatically activates when network restrictions are configured
# Works transparently with your existing network permission settings

Details:

• Uses bubblewrap for containerization on Linux systems
• Implements Unix domain socket proxy with socat for network isolation
• TCP-to-Unix forwarding maintains connectivity while enforcing restrictions
• Evidence: zr2() at line 370283, Mq6() at line 370273

What: Claude Code can now connect to MCP servers via SDK transport How to use:

# Configure SDK-based MCP servers in your settings
# SDK transport complements existing HTTP and WebSocket options

Details:

• New "sdk" type for MCP server configurations
• Built-in transport class for SDK-based communication
• Seamless integration with existing MCP infrastructure
• Evidence: class _D0 at line 387347, uBB() at line 388121, sendMcpMessage() at line 430038

What: Automatically save work-in-progress to shadow Git repositories How to use:

# Enable in settings when available (feature flag controlled)
# Shadow repos are automatically managed and cleaned up after 30 days

Details:

• Creates shadow repositories to preserve uncommitted changes
• Automatic cleanup of old shadow repos after one month
• Tracks last access time for efficient storage management
• Evidence: ZmB() at line 419608, GmB() at line 419705, checkpointingShadowRepos at line 355280

What: Protection against IFS-based shell injection attacks How to use:

# Automatic - Claude Code now validates commands for dangerous patterns
# Commands with IFS manipulation will require explicit approval

Details:

• Detects IFS variable usage that could bypass security validation
• Comprehensive safe flags validation for common shell commands
• Covers git, xargs, sed, sort, file, and other commands
• Evidence: gN6() at line 374933, F1B variable at line 379461

What: New keyboard shortcut for pasting images from clipboard How to use:

# Press Alt+V to paste images directly from your clipboard
# Works in all contexts where image input is supported

Details:

• Platform-specific keybinding (Alt+V on Windows/Linux, Shift+Tab on macOS)
• Consistent with system clipboard conventions
• Evidence: Eu variable at line 363750

What: Better proxy bypass logic for excluded hosts Details:

• New dedicated functions for checking NO_PROXY environment variable
• Intelligent URL matching against proxy bypass patterns
• Supports wildcards, domain suffixes, and port-specific rules
• Evidence: VJ4() at line 354027, KJ4() at line 354030

What: Unified cross-platform network isolation Details:

• Single entry point for both macOS and Linux sandboxing
• Better error messages for uninitialized proxy states
• Improved proxy port management with parameterized functions
• Evidence: Er2() at line 370309 replaces platform-specific Bs2()

What: Fixed permission mode settings not persisting across sessions Details:

• Corrected property name mismatch (saved as "mode" but read as "defaultMode")
• Permission modes now correctly persist when changed
• Added helper function for cleaner source validation
• Evidence: setMode case at line 344856 now uses defaultMode consistently

Error messages for request timeouts no longer include technical hints about API_TIMEOUT_MS, providing cleaner user experience.

• Feature flag checking system enhanced with dedicated function
• MCP-related constants added for token management
• Various function renamings for better code organization
