WebSharper 4 (codename Zafir) beta-4

Version 4.0.133.15-beta4

Improvements

• #614: printf and Json.Serialize/Deserialize now create global helper functions for each type only once.
  This required: new macro functionality to create top level functions, custom key/value dictionary in assembly metadata accessible by macros.
• #615: Fixed Json.Serialize issue with using generic unions with both simple value and inlinable record type
• #582: Improvements to client-side implementations (proxies) to a number of List/Seq/Array module functions. Includes better sorting, List.append does not iterate through second list, more specialized conversions and map family of functions.

Deprecated

• Json.SerializeWith and similar functions taking a custom serializer object have been removed
