For those non-Linux users who’ve wanted to tinker with Regina:
Regina 4.92 came out a couple of weeks ago, and has some big portability improvements. Mac users now have a simple drag-and-drop install (no need for fink), and for the first time there is an installer for MS Windows. As always, there are also ready-made packages for several GNU/Linux distributions.
The new version adds features such as fundamental normal surfaces and boundary slopes for spun-normal surfaces, and the user interface is cleaner. For more information or to have a play, hop over to regina.sourceforge.net.
