[ANN] New release of Menhir

I would like to announce a new release of Menhir, the LR(1) parser generator.

This release fixes the termination test that takes place before parameterized symbols are
expanded away. The previous test was both unsound (it would accept grammars
whose expansion did not terminate) and incomplete (it would reject
grammars whose expansion did terminate). The new test is believed to be
sound and complete. (Thanks to Martin Bodin for prompting us to look into this issue.)

It is available as of now via opam.
