Well, I'm about two months late in blogging about this, but, still: JavaCC 4.1 is out! It's been close to three years since the last release (JavaCC 4.0 came out in Jan 2006), and this new version has a bunch of bug fixes and code cleanups.
The lion's share of the work for this release (and over the past few years in general) was done by Paul Cager, with contributions in the form of patches, discussions, and bug reports from many others. You can download this release here, and feedback is always welcome on the mailing lists.
Finally, I must plug my JavaCC book. It's a perfect Christmas present for your friends who enjoy reading EBNF!
