We're very pleased to announce that F# 1.1.12 is available for download. (note: since the time of writing this has been updated to F# 22.214.171.124)
This release incorporates a significant number of minor improvements combined with two new features: a lightweight syntax option and a feature called Active Patterns. Both are considered "beta" features: minor changes and extensions may be made in future releases, though we expect both to stick in essentially the form we have presented them here.
The detailed release notes for 126.96.36.199 can be found here.
Thanks to all those at MSR, Microsoft and readers of The Hub who have been using earlier versions of this release.
The F# team
