Release notes

Nanocoder v1.21.0

What's Changed

  • Added /compact command for context compression with --restore flag support to restore messages from backup. The command now includes auto-compact functionality, consistent token counting, and improved compression for very long messages. Thanks to @Pahari47.

  • Added hierarchical configuration loading for both provider configs and MCP servers. Local project configurations now properly override global settings, and Claude Code's object-style MCP configuration format is now supported. Thanks to @Avtrkrb.

  • Added alwaysAllow configuration option for MCP servers to auto-approve trusted tools without confirmation prompts. Thanks to @namar0x0309.

  • Added automatic tool support error detection and retry mechanism. Models that don't support function calling are now detected and requests automatically retry without tools. Thanks to @ThomasBrugman.

  • Added --version and --help CLI command options for quick reference. Thanks to @Avtrkrb.

  • Added /quit command as an alternative way to exit Nanocoder. Thanks to @Avtrkrb.

  • Added /nanocoder-shape command for selecting branding font styles.

  • Added keyboard shortcuts documentation to README.

  • Renamed /setup-config to /setup-providers for clearer naming.

  • Improved /mcp command modal with better colors and title formatting. Thanks to @Avtrkrb.

  • Improved /help command title heading styling. Thanks to @Avtrkrb.

  • Added CLI test harness for non-interactive mode testing. Thanks to @akramcodez.

  • Added comprehensive test suite for tool error detection. Thanks to @ThomasBrugman.

  • Added DisableToolModels documentation to README. Thanks to @ThomasBrugman.

  • Fix: Resolved bash tool keeping processes alive after command completion.

  • Fix: Corrected log directory paths and enabled file logging in production.

  • Fix: Improved deprecation message for MCP config to display correct config directory instead of hardcoded Linux path. Thanks to @Avtrkrb.

  • Fix: Resolved shell command security scanning alerts built from environment values. Thanks to @Avtrkrb.

  • Fix: Security audit dependencies updated.
