[ Update: The release candidate has been updated to F# 1.9.3.14. The additional changes are documented with the release notes below ]

I'm very glad to say that an updated release candidate for  F# 1.9.3 is now available (MSI, ZIP). This is F# 1.9.3.14. Here are the full release notes for 1.9.3.14. This is primarily a stabilization release, with some new language and library work.  Thanks to James, Ralf, Jomo and Luke for helping us put this together.

[ Note: This release renames fslib.dll and mllib.dll to FSharp.Core.dll and FSharp.Compatibility.dll, a change we've been meaning to make for some time. ]

if you're looking for F# 1.9.3.7 then the MSI and ZIP are still available

Language Additions:

• Multiple Custom Value Syntax

Language Cleanup

·         As part of the productization of F# we’re looking at doing a “spring clean” of some of the things we’ve got in the language that we may not want to support in the productized version. As a first step, we’ve added warnings and deprecations to some language constructs. See the full release notes for details.

Bug Fixes
