 ## Changelog
 
-### V0.1 (20-Jun-21)
+### V0.2 (27-Jul-21)
+
+- Cosmetics: Added (same) icon for plugin as for file type.
+- Performance improvement: Use Word-Index for global labels and symbols instead of iterating over the file.
+- Performance improvement: Use Stub-Index for global labels and symbols.
+- Bugfix: No longer reports a syntax error when file lacks terminating End-Of-Line.
+- Enhancement: Registers are now offered for code completion, making editing less annoying.
