The top priority for this release was improving upon performance while retaining backwards compatibility with IronPython 2.0. One of many notable areas we’ve improved upon is that float-integer comparisons are now 74% faster than they were in 2.0. A full report documenting changes in interpreter performance from 2.0 to 2.0.1 can be found at: Comparing IronPython 2 and 2.0.1 Performance
A special thanks goes out to Resolver Systems for helping us in identifying areas needing performance improvements.
