jcl has added a mtl_remove() function so if you correctly use mtl_remove() and bmap_remove() then there won't be a memory leak.
materials are so small though that the memory leak probably wouldn't do any harm. caring for the bitmaps is more important.

The handedness of the binormal is now stored in the 4th tangent coordinate of every vertex. This avoids shader problems with mirrored coordinates.
because of this change the current plugin version won't work anymore with the next engine release. the registered users will get an updated version.
