1.6.2
* [Fix `dhall-json` for new `Prelude.JSON.Type`](https://github.com/dhall-lang/dhall-haskell/pull/1631)
* Version 13.0.0 of the Prelude caused the `JSON` type to change, which
broke `dhall-json`'s support for that type
* This release fixes that (and still supports the old `JSON` type)
1.6.1
* [Fix typos in error messages](https://github.com/dhall-lang/dhall-haskell/pull/1595)
1.6.0
* BREAKING CHANGE: [Move `HsYAML` code to a new `dhall-yaml` package](https://github.com/dhall-lang/dhall-haskell/pull/1514)
* This package is now fully BSD-licensed (both for the JSON and YAML
utilities)
* The GPL-licensed YAML utilities are now provided as part of the
`dhall-yaml` package
* Note that this package still provides `dhall-to-yaml` and the `dhall-yaml`
package provides a separate `dhall-to-yaml-ng` executable
* This is a breaking change in the following respects:
* The YAML-related modules in this package were renamed
* This package no longer accepts a `-fgpl` cabal configure flag
* This package no longer provides the `yaml-to-dhall` executable (which
now resides within the `dhall-yaml` package)
* [BREAKING CHANGE: Rename some options of `dhall-to-{json,yaml}` to more consistent ones](https://github.com/dhall-lang/dhall-haskell/issues/1430):
* rename `--omitEmpty` to `--omit-empty`
* rename `--preserveNull` to `--preserve-null`
* rename `--noMaps` to `--no-maps`
* drop `--omitNull` as redundant because of `--preserve-null` (see below)
* [BUG FIX: Handle empty maps correctly](https://github.com/dhall-lang/dhall-haskell/pull/1561)
* `dhall-to-{json,yaml}` now correctly translate empty Dhall maps
to empty JSON dictionaries
* [Add `Dhall.JSON.defaultConversion`](https://github.com/dhall-lang/dhall-haskell/pull/1579)
* [Don't normalize schema before type-checking](https://github.com/dhall-lang/dhall-haskell/pull/1555)
* This improves the error messages for `{json,yaml}-to-dhall`
* [Fix `dhall-to-yaml` to quote special strings](https://github.com/dhall-lang/dhall-haskell/pull/1474)
* [Make some of CLI options for `dhall-json` more consistent](https://github.com/dhall-lang/dhall-haskell/pull/1475)
1.5.0
* [BREAKING CHANGE: Enable `--pretty` by default for `dhall-to-json`](https://github.com/dhall-lang/dhall-haskell/issues/716)
* [BREAKING CHANGE: Enable `--omitNull` by default for `dhall-to-{json,yaml}`](https://github.com/dhall-lang/dhall-haskell/pull/1365)
* To recover the old behavior use the `--preserveNull` flag
* Add support for building against the `HsYAML` package [#1248](https://github.com/dhall-lang/dhall-haskell/pull/1248) / [#1417](https://github.com/dhall-lang/dhall-haskell/pull/1417) / [#1420](https://github.com/dhall-lang/dhall-haskell/pull/1420)
* To enable the use of `HsYAML`, enable the `-fgpl` `cabal configure` flag,
which means that anything built using that flag is GPLv3 licensed
* By default `dhall-json` builds against `aeson-yaml` which is BSD-3
licensed
* The `yaml-to-dhall` executable is only available with the `-fgpl` flag,
meaning that it is necessarily GPLv3 licensed
* [New `--omissible-lists` flag for `{json,yaml}-to-dhall`](https://github.com/dhall-lang/dhall-haskell/pull/1414)
* This flag is sort of the inverse of the `--omitEmpty` flag, meaning that
missing YAML/JSON lists can be translated to present (but empty) Dhall
lists
1.4.1
* [Enable `--records-strict` by default for `{json-yaml}-to-dhall`](https://github.com/dhall-lang/dhall-haskell/pull/1181)
* [Fix `--file` flag for `dhall-to-{json,yaml}`](https://github.com/dhall-lang/dhall-haskell/pull/1191)
* [Fix `--version` flag for `{yaml,json}-to-dhall`](https://github.com/dhall-lang/dhall-haskell/pull/1199)
* [`Nesting`: Support empty alternatives as contents](https://github.com/dhall-lang/dhall-haskell/pull/1204)
* [Fix `yaml-to-dhall` support for empty objects](https://github.com/dhall-lang/dhall-haskell/pull/1186)
* [Throw error when union value is incompatible with inline nesting](https://github.com/dhall-lang/dhall-haskell/pull/1226)
* [Add `--output` options](https://github.com/dhall-lang/dhall-haskell/pull/1304)
* [Minor bug fixes for `yaml-to-dhall` error messages](https://github.com/dhall-lang/dhall-haskell/pull/1305)

names

again
* See: https://github.com/dhall-lang/dhall-haskell/pull/1080

values
* See: https://github.com/dhall-lang/dhall-haskell/pull/1007
* Feature: Eta support for `dhall-json`
* See: https://github.com/dhall-lang/dhall-haskell/pull/1013

can pattern match on them
* See: https://github.com/dhall-lang/dhall-haskell/pull/1094
* Pretty-print output of `{json,yaml}-to-dhall`
* See: https://github.com/dhall-lang/dhall-haskell/pull/1150
1.3.0
* BREAKING CHANGE: Change YAML/JSON encoding for `NaN`/`Infinity`/`-Infinity`

representations instead of `null`/`MIN_DOUBLE/`/`MAX_DOUBLE`
* See: https://github.com/dhall-lang/dhall-haskell/pull/946
* BREAKING CHANGE: Isolate YAML code to one modulee
