v0.7.0

• Switched packaging to pyproject.toml.

v0.6.0

• Fixed encoder bug that caused invalid output for inline strings starting
  with a quotation mark (#3).
• Encoder now uses single-character string delimiters in more cases.
• Fixed bug that prevented decoding empty block strings and empty block
  comments.
• Fixed bug that prevented lists in indentation-based syntax immediately
  under sections.

v0.5.0

• .value with roundtrip AST nodes now gives correct, updated value for
  collections that have been modified (#1).
• dump() now works (#2).

v0.4.0

• Many improvements and new features for RoundtripAst.
  • Improved support for replacing keys and values. There is experimental
    support for replacing dicts and lists, and now full support for all other
    data types.
  • Added option enforce_types, which provides experimental support for
    replacing keys and values with objects of a different data types.
  • Added support for custom encoders.
  • Added preliminary support for __getitem__-style access (for example,
    ast['key'].value).
  • Added access to trailing comments (not doc comments) with new node
    attributes key_trailing_comment, value_trailing_comment,
    value_start_trailing_comment, and value_end_trailing_comment. These
    also allow modification of existing trailing comments.
• New loading options: custom_types allows use of custom data types.
  empty_default is a function that is called to produce a
  default value when there is no data to load.
• New dumping options that control output appearance, data types, and data
  structures: aliases, circular_references, integers,
  only_ascii_unquoted, only_ascii_source, extended_types,
  python_types, baseclass, trailing_commas, compact_inline,
  inline_depth, nesting_indent, start_list_item, and
  flush_start_list_item.
• Fixed bug with round-tripping bools.
• Fixed bug in error reporting for reserved words like inf in key paths.

v0.3.0

• Added decoder options aliases, circular_references, custom_parsers,
  and python_types.
• Decoder now disables circular references by default. They may be enabled
  with new option circular_references.
• More powerful alias support, particularly for alias paths passing through
  inherited keys.
• Moved decoder tuple support from option extended_types to new option
  python_types.
• Complex numbers starting with inf or nan now work with decoder.
• Fixed bug in doc comment-tag interaction.

v0.2.1

• Fixed bugs with decoder options only_ascii_source and
  only_ascii_unquoted.
• Prevent explicit typing of none, true, and false.
• Tag keyword indent no longer affects text after an escaped newline.
• Fixed bug that prevented inline collections from being tagged if not at line
  start.
• RootNode and DictlikeNode now have _state attribute.
• Improved grammar.

v0.2.0

• Significant speed improvements: around 25-30% faster on decoding benchmark
  than v0.1.1.
• Added encoder options hex_floats and max_nesting_depth.
• Added decoder options extended_types, float_overflow_to_inf,
  integers, only_ascii_unquoted, only_ascii_source, max_nesting_depth.
• Added support for tags, which enable explicit typing and object labeling
  (for later referencing via aliases). Tags also allow indent and newline
  to be specified for multiline strings. Added support for bytes, base16,
  and base64 types via tagging.
• Added support for aliases.
• Encoder now detects circular references.
• Improved error handling and error messages.
• setuptools is used for installation if available.

v0.1.1

• Added MANIFEST.in to include README.rst in sdist.

v0.1.0

• First release with mostly complete basic feature set.
