Breaking changes not in documentation: buffer name change, lists -> tuples

Somewhere between 4.4.0 and 5.6.1, the two versions I was able to test (possibly intentional, but 5.0.0 is not on PyPI), two breaking changes were introduced that I did not see mentioned.

  1. The ParseInfo buffer attribute became tokenizer.
  2. The values in the parse tree for successive literals (e.g. my rule = "string" "string" "string";) changed from lists to tuples.

These should be added to the changelog as well as the Grako compatibility page (which, by the way, is awesome -- I was able to upgrade from Grako very easily, kudos!)

I will tend to this.

Do you have an idea about which part of the documentation should be updated?

I'm sure I solved this. I don't know why Github didn't pick it up.
