* Add export `docRoot :: Doc n -> n` field accessor for convenience ([#32](https://github.com/haskell-hvr/HsYAML/issues/32))
## 0.2.0.0
This release incorporates the work from [Vijay Tadikamalla's GSOC 2019 Project](https://vijayphoenix.github.io/blog/gsoc-the-conclusion/).
Highlights of this major release include support for emitting YAML as
well as providing direct access to source locations throughout the
parsing pipeline for improved error reporting.
* Changes in `Data.YAML` module
* YAML 1.2 Schema encoders ([#21](https://github.com/haskell-hvr/HsYAML/pull/21))
* New `ToYAML` class for encoding Haskell Data-types from which YAML nodes can be constructed ([#20](https://github.com/haskell-hvr/HsYAML/pull/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](https://github.com/haskell-hvr/HsYAML/pull/19))
* Provide location-aware `failAtNode` alternative to `fail`
* Changes in `Data.YAML.Event` module
* Preserve and round-trip Comments at Event level([#24](https://github.com/haskell-hvr/HsYAML/pull/24))
* New `Comment` Event to preserve comments while parsing
* Some additional implementations to preserve and round-trip comments
* Fix issue [#22](https://github.com/haskell-hvr/HsYAML/issues/22)
* New `EvPos` type for recording event and their corresponding position ([#19](https://github.com/haskell-hvr/HsYAML/pull/19))
* Preserve Flow Mapping and Flow sequence ([#18](https://github.com/haskell-hvr/HsYAML/pull/18))
* Features to preserve Literal/Folded ScalarStyle ([#15](https://github.com/haskell-hvr/HsYAML/pull/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](https://github.com/haskell-hvr/HsYAML/issues/13), [#14](https://github.com/haskell-hvr/HsYAML/issues/14))
---
#### 0.1.1.3
* Fix bug in float regexp being too lax in the JSON and Core schema ([#7](https://github.com/hvr/HsYAML/issues/7))
* Remove dependency on `dlist`
#### 0.1.1.2
* Tolerate BOM at *each* `l-document-prefix` (rather than only at the first one encountered in a YAML stream)
* Workaround broken `mtl-2.2.2` bundled in GHC 8.4.1 ([#1](https://github.com/hvr/HsYAML/issues/1))
* Relax to GPL-2.0-or-later
#### 0.1.1.1
* Reject (illegal) non-scalar code-points in UTF-32 streams
* 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
### 0.1.1.0
