Version 1.2

• #154: Add SkippableOptionFields enum to further customize the skipping of fields of type option and voption with WithSkippableOptionFields.

  • SkippableOptionFields.FromJsonSerializerOptions is the default and equivalent to WithSkippableOptionFields(false): fields of type option and voption are skipped if used with JsonIgnoreCondition.WhenWritingNull.
  • SkippableOptionFields.Always is equivalent to WithSkippableOptionFields(true): fields of type option and voption are always skipped.
  • SkippableOptionFields.Never: fields of type option and voption are never skipped.

• #159: Throw an exception when trying to deserialize null into a record or union in any context, rather than only when they are in fields of records and unions.

• #160: Fix WithSkippableOptionFields(false) not working for voption.

• #161: Allow using single-case unions as keys in all dictionary types.
  NOTE: This requires System.Text.Json 8.0.

• #162: Add option .WithMapFormat(MapFormat) to customize the format of F# maps.

  • MapFormat.Object always serializes maps as objects. The key type must be supported as key for dictionaries.
    NOTE: This requires System.Text.Json 8.0.
  • MapFormat.ArrayOfPairs always serializes maps as JSON arrays whose items are [key,value] pairs.
  • MapFormat.ObjectOrArrayOfPairs is the default: maps whose keys are string or single-case unions wrapping string are serialized as JSON objects, and other maps are serialized as JSON arrays whose items are [key,value] pairs.

• #163: Add StructuralComparison to the type Skippable<_>.

• #164: When deserializing a record with JsonIgnoreCondition.WhenWritingNull, when a non-nullable field is missing, throw a proper JsonException rather than a NullReferenceException.
