New version of F# just released

In its way from research language to commercial language, Don Syme just announced that, silently, on May the 1st version 1.9.4.15 of F# was released.

This new version incorporates a number of specific enhancements (F# is now basically in stabilization mode, so we really shouldn't expect significative changes to the language). By the way, the example in the picture shows my idea for solving Problema 2 of Project  Euler: find the sum of all the even-valued terms in the Fibonacci sequence which do not exceed four million. For an explanation of how it works, I suggest you this Dustin Campbell blog, which proposes a solution similar to mine with a couple of elegant touches and, above all, with a detailed and engaging explanation.
