• Add full support for decimal numbers (on supported platforms). This takes the form of a new JSON variant .decimal, any relevant accessors, and full parsing/decoding support with the new option .useDecimals. With this option, any number that would have been decoded as a Double will be decoded as a Decimal instead.
• Add a set of forEach accessors for working with arrays, similar to the existing map and flatMap accessors.

• Handle UTF-32 input.
• Detect UTF-16 and UTF-32 input without a BOM.
• Fix bug where we weren't passing decoder options through for UTF-16 input.

• Change how options are provided to the encoder/decoder/parser. All options are now provided in the form of a struct that uses array literal syntax (similar to OptionSets). The old methods that take strict/pretty flags are now marked as deprecated.
• Add a new depth limit option to the decoder, with a default of 10,000.
• Implement a new test suite based on JSONTestSuite.
• Fix a crash if the input stream contained a lone trail surrogate without a lead surrogate.
• Fix incorrect parsing of numbers of the form 1e-1 or 1e+1.
• When the strict option is specified, stop accepting numbers of the form 01 or -01.
• Add support for UTF-16 when decoding a Data that has a UTF-16 BOM.
• Skip a UTF-8 BOM if present when decoding a Data.

• Full JSON stream support. JSONParser and JSONDecoder can now both operate in streaming mode, a new type JSONStreamDecoder was added as a lazy sequence of JSON values, and a convenience method JSON.decodeStream(_:) was added.
• Add support for pattern matching with JSONParserError. It should now work just like any other error, allowing you to say e.g. if case JSONParserError.invalidSyntax = error { … }.* Add Hashable to JSONEvent and JSONParserError.
• Make JSONParserError conform to CustomNSError for better Obj-C errors.
• Rename JSONEventGenerator to JSONEventIterator and JSONParserGenerator to JSONParserIterator. The old names are available (but deprecated) for backwards compatibility.

This release fixes CocoaPods support, and also improves compile times slightly.

This release supports Swift 3.

This release supports Swift 2.3, in addition to the following changes:

• Add setters for basic accessors so you can write code like json["foo"].object?["key"] = "bar".
• Add optional NSError userInfo provider for JSONError. Setting this up requires calling JSONError.registerNSErrorUserInfoProvider().

• Add new set of convenience JSON initializers.
• Change description and debugDescription for JSON and JSONObject to be more useful.
  description is now the JSON-encoded string.
• Implement CustomReflectable for JSON and JSONObject.

• CocoaPods support.

• Linux support.
• Swift Package Manager support.
• Rename instances of plist in the API to ns. The old names are still available but marked as deprecated.
• Support the latest Swift snapshot (2012-02-08).
