Version 0.8

• #30: Unwrap 'T voption with JsonUnionEncoding.UnwrapOption. Thanks @johlrich!

• #32: Add JsonUnionEncoding.UnwrapSingleFieldCases, which encodes the field of single-field cases as x instead of [x]. Include it in JsonUnionEncoding.FSharpLuLike.

• #33: Fix "read too much or not enough" when parsing a list of unions with JsonUnionEncoding.UnwrapFieldlessTags.

• #36: BREAKING CHANGE: During deserialization, throw an exception when a field of a record or union has value null, unless the type of this field is option, voption, or a union with UseNullAsTrueValue. Thanks @drhumlen!

  New option allowNullFields disables this behavior.

• #38: Add more consistent names for options:

  • BareFieldlessTags becomes UnwrapFieldlessTags;
  • SuccintOption becomes UnwrapOption;
  • EraseSingleCaseUnions becomes UnwrapSingleCaseUnions.

  The previous names are marked Obsolete.

Version 0.7

• #3: Add support for PropertyNamingPolicy on record and union fields.
• #22: Add support for DictionaryKeyPolicy for Map<string, 'T>.
• #27: Add unionTagNamingPolicy option to JsonFSharpConverter and JsonFSharpConverterAttribute to customize the naming policy for union tag names.
• #26: Add JsonUnionEncoding.EraseSingleCaseUnions, which encodes single-case single-field unions the same as the value in the field.
  BREAKING CHANGE: This is now the default option.
• #5: Add support for PropertyNameCaseInsensitive on record and union fields.
  Add unionTagCaseInsensitive option to JsonFSharpConverter and JsonFSharpConverterAttribute to customize the case sensitivity for union tag names.

Version 0.6

• #4: Add support for standard option IgnoreNullValues on record and union fields.
• #13: Add support for JsonPropertyNameAttribute on union cases to set the tag name to use for this case.
• #16: Add JsonUnionEncoding.SuccintOption, which encodes Some x the same as x.
  BREAKING CHANGE: This is now the default option.
• Add unionTagName and unionFieldsName option to customize the "Case" and "Fields" tags for unions.
• Add JsonUnionEncoding.FSharpLuLike, which is equivalent to ExternalTag ||| BareFieldlessTags ||| SuccintOption.
