## 0.11.11.0

* Fix ambiguous occurrence `AesonException`

## 0.11.10.0

* Undo previous change (breakage with aeson 2)

## 0.11.9.0

* Data.Yaml.Pretty: provide key-sorting function with path to parent object [#206](https://github.com/snoyberg/yaml/pull/206)

## 0.11.8.0

* Export `Parse` and `StringStyle` [#204](https://github.com/snoyberg/yaml/pull/204)

## 0.11.7.0

* Support `aeson` 2 [#202](https://github.com/snoyberg/yaml/pull/202)

## 0.11.6.0

* `yaml2json`: add `--help` and `--version` options [#197](https://github.com/snoyberg/yaml/pull/197)
* `json2yaml`: add `--help` and `--version` options [#198](https://github.com/snoyberg/yaml/pull/198)
* Add the `-o` options to both `yaml2json` and `json2yaml` [#200](https://github.com/snoyberg/yaml/pull/200)

## 0.11.5.0

* New functions capable of parsing YAML streams containing multiple documents into a list of results:
  * `decodeAllEither'`
  * `decodeAllFileEither`
  * `decodeAllFileWithWarnings`
  * `decodeAllThrow`
  * `decodeAllFileThrow`

## 0.11.4.0

* add `ToYaml` instance for `String` [#186](https://github.com/snoyberg/yaml/pull/186)

## 0.11.3.0

* Don't wrap up async exceptions [#185](https://github.com/snoyberg/yaml/issues/185)

## 0.11.2.0

* Reduces some of the code duplication between the `encode` and `encodePretty` functions
* The output of `encodePretty` has been improved:
    - Multiline strings now use `Literal` style instead of `SingleQuoted`
    - Special keys are now quoted in mappings [#179](https://github.com/snoyberg/yaml/issues/179)
* Support for complex keys in mappings: [#182](https://github.com/snoyberg/yaml/issues/182)
    - Adds `complexMapping` function to `Data.Yaml.Builder`
    - Decode functions now return a `NonStringKey` error when attempting to decode a mapping with a complex key as it is not possible to decode these to an Aeson `Value`

## 0.11.1.1
