3.0: Less is more

The goal for Argo 3.0 was to work on simplifying some of the complexity by removing extraneous API and improving consistency between Argo and other libraries (including the Swift standard lib). In addition, we've added support for Swift 2.2.

• Update to Swift 2.2 - Leo Mehlig
• Remove Optional versions of <| operators - Gordon Fontenot
• Improve the API for root key decoding - Gordon Fontenot

Non-Breaking Changes

• Update errors for RawRepresentable types. - Paul Young
• Remove CustomStringConvertible constraint on typeMismatch function - Dapeng Gao
• Use an autoclosure for the rhs of <|> - Gordon Fontenot
• Generalize the type for sequence taking a dict - Gordon Fontenot

Misc

• (hopefully) the entire public API now has inline documentation!
