Release 0.119.1

Bug fix:

Fixed issue wjson dump() not formatting booleans correctly #174

Release 0.119.0

Name change:

• The name json_staj_reader has been deprecated and renamed to json_pull_reader

Bug fix:

• Fixed a bug in json function empty() when type is byte_string.
• Fixed a bug with preserving semantic_tag_type when copying json values of long string type.

Changes:

  big_decimal, or if array value is tagged with big_float.

Release 0.118.0

Name change

• The json_options name dec_to_str has been deprecated and renamed to lossless_number.

New features

• New csv option lossless_number. If set to true, parse numbers with exponent and fractional parts as strings with
  semantic tagging semantic_tag_type::big_decimal (instead of double.) Defaults to false.

• A class jsonpointer::address has been introduced to make it simpler to construct JSON Pointer addresses

Release 0.117.0

Deprecated features:

• cbor_view has been deprecated. Rationale: The complexity of supporting and documenting this component
  exceeded its benefits.

New features

• New json_options option dec_to_str. If set to true, parse decimal numbers as strings with
  semantic tagging semantic_tag_type::big_decimal instead of double. Defaults to false.

• The ojson (order preserving) implementation now has an index to support binary search
  for retrieval.

• Added std::string_view detection

• jsoncons-CBOR semantic tagging supported for CBOR tags 32 (uri)

Name changes (non-breaking)

• The json options name bignum_chars_format has been deprecated and replaced with big_integer_chars_format.
• big_integer_chars_format::integer (bignum_chars_format::integer) has been deprecated and replaced with
  big_integer_chars_format::number
• The json_options function bignum_format has been deprecated and replaced with big_integer_format

Changes to floating-point printing

• If the platform supports the IEEE 754 standard, jsoncons now uses the Grisu3 algorithm for printing floating-point numbers,
  falling back to a safe method using C library functions for the estimated 0.5% of floating-point numbers that might be rejected by Grisu3.
  The Grisu3 implementation follows Florian Loitsch's grisu3_59_56
  implementation. If the platform does not support the IEEE 754 standard, the fall back method is used.

• In previous versions, jsoncons preserved information about the format, precision, and decimal places
  of the floating-point numbers that it read, and used that information when printing them. With the
  current strategy, that information is no longer needed. Consequently, the floating_point_options
  parameter in the do_double_value and double_value functions of the SAX-style interface have
  been removed.

• The json functions precision() and decimal_places() have been deprecated and return 0
  (as this information is no longer preserved.)

• The constructor json(double val, uint8_t precision) has been deprecated.

• Note that it is still possible to set precision as a json option when serializing.

Release 0.116.0

New features:

• New jsonpath functions keys and tokenize.

• jsoncons-CBOR data item mappings supported for CBOR tags 33 (string base64url) and 34 (string base64)

Release 0.115.0

New features:

• bson UTC datetime associated with jsoncons semantic_tag_type::timestamp

• New traits class is_json_type_traits_impl that addresses issues
  #133 and
  #115 (duplicates)

• Following a proposal from soberich, jsonpath functions on JSONPath expressions
  are no longer restricted to filter expressions.

• New jsonpath functions sum, count, avg, and prod have been added.

• Added semantic_tag_type::base16, semantic_tag_type::base64, semantic_tag_type::base64url

Non-breaking changes:

• The json constructor that takes a byte_string and a byte_string_chars_format
  has been deprecated, use a semantic_tag_type to supply an encoding hint for a byte string, if any.

• The content handler byte_string_value function that takes a byte_string and a byte_string_chars_format
  has been deprecated, use a semantic_tag_type to supply an encoding hint for a byte string, if any.

Changes:

• The byte_string_chars_format parameter in the content handler do_byte_string_value function
  has been removed, the semantic_tag_type parameter is now used to supply an encoding hint for a byte string, if any.

Release 0.114.0

Bug fixes:

• On Windows platforms, fixed issue with macro expansion of max when
  including windows.h (also in 0.113.1)

• Fixed compile issue with j = json::make_array() (also in 0.113.2)

Breaking changes to jsoncons semantic tag type names:

• semantic_tag_type::bignum to semantic_tag_type::big_integer
• semantic_tag_type::decimal_fraction to semantic_tag_type::big_decimal
• semantic_tag_type::epoch_time to semantic_tag_type::timestamp

Non-breaking name changes:

The following names have been deprecated and renamed (old names still work)

• bignum_value to big_integer_value in json_content_handler

• decimal_value to big_decimal_value in json_content_handler

• epoch_time_value to timestamp_value in json_content_handler

• cbor_bytes_serializer to cbor_buffer_serializer

• msgpack_bytes_serializer to msgpack_buffer_serializer

• json_serializing_options to json_options

• csv_serializing_options to csv_options

• parse_error to serialization_error

The rationale for renaming parse_error to serialization_error
is that we need to use error category codes for serializer
errors as well as parser errors, so we need a more general name
for the exception type.

Message Pack enhancements

• New msgpack_serializer that supports Message Pack bin formats

• New msgpack_parser that supports Message Pack bin formats

• encode_msgpack and decode_msgpack have been
  rewritten using msgpack_serializer and msgpack_parser,
  and also now support bin formats.

New features:

• decode from and encode to the Universal Binary JSON Specification (ubjson) data format

• decode from and encode to the Binary JSON (bson) data format

• The cbor, msgpack and ubjson streaming serializers now validate that the expected number of
  items have been supplied in an object or array of pre-determined length.

Release 0.113.2

Bug fix

• On Windows platforms, fixed issue with macro expansion of max when
  including windows.h

Release 0.113.1

Bug fix

Fixed compile issue with j = json::make_array().

Release 0.113.0

Bug fix

• Fixed issue with indefinite length byte strings, text strings, arrays,
  and maps nested inside other CBOR items (wasn't advancing the
  input pointer past the "break" indicator.)

Changes

• FILE and LINE macros removed from JSONCONS_ASSERT
  if not defined _DEBUG (contributed by zhskyy.)

• semantic_tag_type name decimal changed to decimal_fraction

New CBOR feature

• CBOR semantic tagging of expected conversion of byte strings
  to base64, base64url and base16 are preserved and respected in JSON
  serialization (unless overridden in json_serializing_options.)

• CBOR semantic tagging of bigfloat preserved with semantic_tag_type::bigfloat

• CBOR non text string keys converted to strings when decoding
  to json values

Changes to json_serializing_options

New options

• spaces_around_colon (defaults to space_after)
• spaces_around_comma (defaults to space_after)
• pad_inside_object_braces (defaults to false)
• pad_inside_array_brackets (defaults to false)
• line_length_limit (defaults to '120`)
• new_line_chars (for json serialization, defaults to \n)

nan_replacement, pos_inf_replacement, and neg_inf_replacement are deprecated (still work)
These have been replaced by

• nan_to_num/nan_to_str
• inf_to_num/inf_to_str
• neginf_to_num/neginf_to_str (default is - followed by inf_to_num/inf_to_str)

nan_to_str, inf_to_str and neginf_to_str are also used to substitute back to nan, inf and neginf in the parser.

• Long since deprecated options array_array_block_option,
  array_object_block_option, object_object_block_option and
  object_array_block_option have been removed.

• The names object_array_split_lines, object_object_split_lines,
  array_array_split_lines and array_object_split_lines have
  been deprecated (still work) and renamed to object_array_line_splits,
  object_object_line_splits, array_array_line_splits and array_object_line_splits.
  Rationale: consistency with line_split_kind name.

Changes to json_serializer

• Previously the constructor of json_serializer took an optional argument to
  indicate whether "indenting" was on. json_serializer now always produces
  indented output, so this argument has been removed.

• A new class json_compressed_serializer produces compressed json without
  indenting.

  The jsoncons functions that perform serialization including json::dump,
  pretty_print and the output stream operator are unaffected.
