Release 10.0.0

New features

• #592 adds the ability specify additional indentation for lists. By default, the emitter emits:

  list:
  - item1
  - item2
  

  By using this option, the emitter will output:

  list:
    - item1
    - item2
  

Bug fixes

• #598 Fixed AnchorNotFoundException if there is a reference to an anchor of a node which is being deserialized. This happens in cyclic references.

Other changes

• Breaking - Binary serialization support has been removed as there was no practical use-case for it.

• Refactor Portability.cs into conditionally included files to improve maintainability.
  There is now a set of directories under YamlDotNet/Helpers/Portability. Each directory's name contains a list of target platforms, separated by +. Each of those files is included only when building for one of those target platforms. Each directory may also contain a subsirectory named others. The files in this directory are included only when building for one target platform that is not in it's parent name.

• Make the type Nothing a ValueType
  There's no need for it to be a reference type.

• Use a custom type to represent anchor names
  This enables the compiler to detect when we pass something else
  where an anchor name is expected.

• Use a custom type to represent tag names
  This enables the compiler to detect when we pass something else
  where a tag name is expected.

• Release notes are no longer stored in the repository, because this forced a new meaningless commit to be created for each release.
