There has been a surprising amount of new features, fixes, and doc improvements since 0.4, so I'm wondering if it's time for a new release. Are there any major todos before that? * Maybe doc additions if they're close. * Of the current pull requests, only SSIM and template-matching are close, but I don't think I'll have much time to sort out the issues with template-matching for awhile. * I was really excited about the image stitching example using HoGs, suggested by Nelle. If it's not close, though, no pressure. Anything else? Cheers! -Tony
