Symbol Collection

- Updated "Fluent UI System Icon" and "Material Symbols". - Added a button to display release notes in the app settings. - Added a settings window for each symbol family in each collection. It is now possible to lock a family to a version, which will automatically select the appropriate version. It is also possible to hide symbols that are unavailable in the selected version. - New default option "last (auto)" in the version selector for new installations. The "last (auto)" option automatically selects the latest available version in the app. - Added an option to include the collection name and its settings when exporting. - Added a feature to detect format errors in current or imported collections. Format errors can occur if the previous version of the app was installed, or if a previously existing format was modified or removed from a symbol family. Format errors can be corrected manually or automatically. - Support for external opening of SYMCOL files. Bug fixes - The "Fluent UI System Icon" family recorded an incorrect format in some cases. - Selected symbols were not automatically deselected after being shared. - Symbols from lower versions of Fluent UI System Icons displayed all formats from higher versions, even those normally unavailable.
