v3.9.0

Version 3.9.0

New features:

• Add YamlVisitorBase as an improved replacement for YamlVisitor
  • YamlVisitor is now obsolete, and will be removed in a future release.
• Ensure compatibility with AOT compilation, for platforms that do not allow dynamic code generation, such as IOS or PS4.
• Add Yaml attribute overrides feature, similar to XML Serializer attribute overrides behavior.
• Add a YamlNodeType enumeration property to nodes.

Bug fixes:

• Fix #166 - Guid conversion to JSON is unquoted.
• Ignore enum value case during deserialization.
• Improve newline handling
  • In some cases, consecutive newlines were incorrectly parsed or emitted.
• Fix #177 - double.MaxValue serialization.
• Register custom type converters with higher precedence than the built-in converters.

Fixes in handling of scalar

New features:

• Add support for different scalar integer bases.
  Addresses issue #113. Adds basic support for deserializing scalar integers
  written in binary, octal, decimal, hex, and base 60, as allowed in the YAML
  specification; see http://yaml.org/type/int.html. Adds unit tests for each
  of these bases as well.
• Add dnx compatibility to the NuGet packages.
• Do not throw exception if a tag does not contain a valid type name.

Fixes and improvements:

• Cache type metadata.
• Fix wrong type when deserializing UInt16.
• Fix handling of special float values, such as NaN, PositiveInfinity and NegativeInfinity.
• Properly quote empty strings.
• Properly handle non-Unicode encodings when emitting scalars.

Add missing overload

This is a minor update that simply adds an overload of YamlStream.Load to be able to specify the EventReader.

Fix bug in portable build

Bug fixes:

• Bug in the GetPublicMethods implementation for portable.

Scalar style, optional anchor assignment and Unity

New features:

• Ability to opt out of anchor assignment during YamlStream.Save().
• Allow the style of scalar properties to be specified through the YamlMember attribute.
• Add solution configuration to target "Unity 3.5 .net Subset Base Class Libraries".

Bug fixes:

• Do not compare nodes by value while assigning anchors. It is the responsibility of the user to use the same reference if they want an alias.
• Fixed #121: Finding properties in parent interfaces

YamlMember improvements

• Add native support of System.Guid serialization.
• Add properties to YamlMemberAttribute:
  • Order: specifies the order of the members when they are serialized.
  • Alias: instructs the deserializer to use a different field name for serialization.
• The YamlAliasAttribute is now obsolete. New code should use YamlMemberAttribute instead.
• Throw proper exceptions, with correct marks, when deserialization of a node fails.

Changes and fixes on the Scanner to make it more usable

• Report the location of comments correctly, when the scanner is created with "skipComments = false"
• In case of syntax error, do not report an empty range and skip to the next token.
• Make the scanner and related types serializable, so that the state of the scanner can be captured and then restored later (assuming that the TextReader is also serializable).

Add a signed package and portable versions

This release adds a signed package and portable versions of the library.

.NET binary serialization

Added suport for .NET binary serialization.

Bugfix

Fix DuplicateAnchorException when using merge keys do merge mappings that contain aliases.

Implement merging a sequence of aliases.
