Important changes are:
- Semantic Annotation has been greatly improved. Many items which were marked as errors are no longer errors; most notably, Map initializers.
- Completion has been enhanced to show Enumerations (values).
- Folding support has been added, and many types of regions are recognized, including those from other popular IDEs.
Also, if you use this plugin regularly, please consider becoming a patron.
