We're proud to announce that we've just released version 1.8 of Resolver One. This version switches to IronPython 2.6, which gives us support for Python 2.6 syntax along with some serious performance improvements. Resolver One is a Windows-based spreadsheet that integrates Python deeply into its recalculation loop, making the models you build more reliable and more maintainable. In version 1.8, we've worked hard on improving performance above and beyond the gains we got from IronPython 2.6, and we've also added a number of new statistical functions, along with various minor bugfixes and smaller enhancements.
