Create linkage symbol nodes in the AST so a linker has access to all global objects that were declared, for error checking, etc. Use it now for all ins/outs/uniforms as well as gl_VertexID and gl_InstanceID.
...
Also fixed a confusing name and added more 'const'.

Bug fix: Make the type of the result of a structure assignment be the type of the structure assigned. That is, the type of the result of the "=" itself, if used in a broader expression. This probably fixes some other subtle problems as well.

Add preprocessor support for parsing doubles.
Add double support to the flex stage.
Put in some of the basic double supported needed in the front end.
Add generic support for version numbers in the preprocessor, and the core, compatibility, and es profiles.

Remove the pack/unpack languages and bring grammar up from 1.1 to 4.2 and fix the affected 1.1 productions and semantics to still work correctly for 1.1 shaders.
...
For 4.2, largely, it is only the grammar that is working. Productions and semantics are mostly missing. Lexical analysis is mostly done, but not in the preprocessor, which still can't handle uint and double literals.
The grammar and token names are reorganized to match the specification, to allow easier comparison between the specification and the working grammar.
