Besides numerous bug fixes, this release brings three major improvements:

Light and dark TextIcon options

TextIcon’s layers can now be configured to apply to the light, dark, or both color themes. Additionally, the color literals in TextIcon’s definition can provide different values for the light and dark color themes.

Highlighting of invisible usages

Usage highlighting of the node at the caret is now restricted to only references that are actually visible in the editor. Usages in nodes that are not actually displayed by the node’s editor are not highlighted.

Reflective editor overhaul

The reflective (default) editor has a new look and feel. The read-only default editor has been merged with the reflective editor, so there’s no longer confusion between the two.
