+ Added lookup acceleration to code index data
+ Added highlighting for functions, types, and macros in code index
+ Default input is now dispatched through an "implicit map" callback
+ Fix: crash when pasting in read only buffer
4.1.6
+ In config.4coder "bind_by_physical_key" uses a key-layout that does not change with language
+ Deprecated GlyphFlag_Rotate90, rotation of immediate mode text is entirely derived from the delta vector
