glMatrix has just received a relatively few minor updates, but in order to make my life easier I've decided to relocate the repository to GitHub so that I could manage all my projects in one place. I've decided to mark the occasion by making glMatrix officially Version 1.0!
There is certainly still room for improvement here, but hopefully GitHub will make it easier to work with the community on features and bugs than Google Code did.
One thing to note, since it's a fairly significant behavioral change: I was notified that quat4.toMat3/4 was producing transposed matricies in older version of glMatrix. I have fixed that in this version but if you were relying on that behavior in older versions you may have to update your code to compensate.
