I’m pleased to announce that F# 1.1.13 is now available! You can download this release from http://research.microsoft.com/fsharp/release.aspx .
This is an exciting release, containing many important enhancements to the language that make F# programming simpler, more powerful and easier to explain and understand. We’re particularly pleased with comprehensions, which, although found in other languages, works beautifully in conjunction with other F# language features such as pattern matching. These also simplify the use of many .NET APIs and collection types. We've also included named arguments, C# 3.0-style property setters and a host of improvements to the F# library, as well as a good number of bug fixes based on feedback from our rapidly expanding user base.
We've placed a summary of the changes in this release on a separate page, a short summary is below. We'll be blogging further about some of the new features in the coming weeks, and look out for the next draft installment of the Expert F# book, coming soon.
