Last month we released a 2nd update for SketchUp 7.1. This release includes a few bug fixes as well as fixes for two reported security issues. Were happy to announce that we have also updated the SDK package with the same security fixes. Please note that the file format for the 7.1 M2 has not changed but we do recommend that folks upgrade to the latest version. It can be downloaded from the SDK page on our code site. If you'd like more info on this update please see our original blog post for the release.
Happy SketchUp Developing!
