- New ToYAML class for encoding Haskell Data-types from which YAML nodes can be constructed (#20)
  - New functions like encodeNode, encodeNode' for constructing AST
  - New functions like encode, encode1, encodeStrict, encode1Strict for supporting typeclass-based dumping
  - Some ToYAML instances and other api
- Modify typeMismatch function to show error source location in error messages (#19)
- Provide location-aware failAtNode alternative to fail
Changes in Data.YAML.Event module
- Preserve and round-trip Comments at Event level(#24)
  - New Comment Event to preserve comments while parsing
  - Some additional implementations to preserve and round-trip comments
- Fix issue #22
- New EvPos type for recording event and their corresponding position (#19)
- Preserve Flow Mapping and Flow sequence (#18)
- Features to preserve Literal/Folded ScalarStyle (#15)
  - New Chomp type denoting Block Chomping Indicator
  - New IndentOfs type denoting Block Indentation Indicator
- New NodeStyle type denoting flow/block style
- Event(SequenceStart,MappingStart) constructors now record NodeStyle
- Style type renamed to ScalarType
- New writeEvents and writeEventsText function
- Event(DocumentStart) now records YAML directive
- Event parser now rejects duplicate/unsupported YAML/TAG directives as mandated by the YAML 1.2 specification
Move some schema related definitions from Data.YAML into the new Data.YAML.Schema module
Make decode, decode1, decodeStrict, decode1Strict, decodeNode, and decodeNode' treat duplicate keys (under the respective YAML schema) in YAML mappings as a loader-error (controllable via new schemaResolverMappingDuplicates schema property)
Define Generic and NFData instances for most types
Fix X38W testcase (#13, #14)

0.1.1.3

Fix bug in float regexp being too lax in the JSON and Core schema (#7)
Remove dependency on dlist

Tolerate BOM at start of stream
Disambiguate choice in l-any-document production regarding token separation of c-directives-end
Fix c-indentation-indicator(n) grammar production when auto-detecting indentation in the presence of empty leading lines; also reject (illegal) auto-indent-level scalars with leading more-indented all-space lines
Complete character escape rules for double-quoted scalars
Minor optimizations
