FastGUI v5.7.6 Update Log

Release Date: December 21, 2025

Major Updates

1. UI Data Structure Optimization

• Added Display Name Field: Added a display name field to the header of UI DAT files
• Improved Name Management: Interface display names are now stored independently from filenames, providing a more flexible naming system
• Backward Compatibility: Existing UI files are automatically compatible with the new structure, and old files will automatically add the display name field on first access

2. /fg set Command Enhancement

• Display Name Update: The /fg set <interface_name> id <newID> command now updates both filename and display name
• Independent Display Name Setting: Added /fg set <interface_name> display <display_name> subcommand to set interface display name separately
• Smart Name Handling: When only setting ID, the display name automatically updates to the new ID; when setting display name, the filename remains unchanged

3. UI Display System Improvement

• Dynamic Name Reading: When players open an interface, the system now reads and displays from the display name field in the DAT file
• Enhanced Multi-language Support: Display names support multi-language variable replacement, such as {player}, {time}, etc.
• Name Formatting: Support for color codes and formatting codes in display names

Technical Improvements

• Data Structure Optimization: Restructured DAT file format, adding version identifier and display name field
• Memory Usage Optimization: Improved UI data loading and caching mechanisms
• Enhanced Error Handling: Added more comprehensive file corruption detection and repair mechanisms
• Performance Boost: Optimized UI opening and name reading performance

Compatibility Notes

• This version is fully compatible with existing interface data and configuration files
• After upgrade, existing UI files will automatically add display name field on first access (defaulting to filename)
• New display name functionality does not affect existing plugins and commands
• Table.dat registration information will automatically update to support the new display name system

Known Issues

• None
