F# 22.214.171.124 has been availalbe for some time now - this wraps up a number of bug fixes, especially for F# Interactive, the toplevel interactive mode (fsi.exe). This release is suitable for use with the final version of VS2005, which has recently been released.
We're also nearing a follow up F# 1.1.4 release, which will include XMLDoc Intellisense support when using external .NET libraries such as the .NET Base Class Libraries and some very cool extensions under Microsoft.FSharp.Math, including a matrix library.
Finally, just to mention that Robert Pickering has been working on using NDoc with F# - as usual great work from Robert! He's put up a sample website containing some of the documentation for F#-on-1.0.
Have fun everyone!
