Version 1.22

• Don't associate with .shader files by default to prevent conflicts with Unity
• Massive rewrite of reference handling, fixes known crash and makes it much more reliable
• Basic support for #include "filename" (notable omissions: no cross-file preprocessor references)
• Basic support for preprocessor macro functions, e.g. #define MAX(a, b) ((a) > (b) ? (a) : (b))
• Region folding for preprocessor if blocks
• Minor improvements which you may or may not notice
