All notable changes to this project will be documented in this file.

## [Unreleased]


## [1.2.0] - 2020-10-12


### Added

- The `402 Payment Required` status,
  along with related callbacks `payment_required?` and
  `handle_payment_required/1`.
- The `451 Unavailable for Legal Reasons` status,
  along with related callbacks `unavailable_for_legal_reasons?/1` and
  `handle_unavailable_for_legal_reasons/1`.
- The `429 Too Many Requests` status,
  along with related callbacks `too_many_requests?/1` and
  `handle_too_many_requests/1`.
  If you return a map containing a `:retry_after` value,
  Liberator will use that to set a `retry-after` header.
- You can also return a `:retry_after` value from any other decision function,
  like `service_available?/1`, or `moved_permanently?/1`, for the same effect.
  See [MDN's docs on the `retry-after` header](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Retry-After)
  for more information on why you'd want to do this.

### Fixed

- Dates in headers are now parsed properly. ([#1](https://github.com/Cantido/liberator/issues/1))

## [1.1.0] - 2020-10-04


### Added

- This changelog!
- The `:trace` option:
  Add `trace: :headers` to your `use Liberator.Resource` statement to
  get an `x-liberator-trace` header added to responses,
  and see the result of all decisions.
- Compression options: `deflate`, `gzip`, and `identity`.

## Changed

- Codecs are now configurable.
  Set the `:media_types` and `:encodings` map in Liberator's config to add your own codecs.

### Removed

- `Liberator.Resource` no longer calls `use Timex`, so your context is less polluted.

## Fixed

- Better wildcard handling during content negotiation
- Content negotiation actually obeys q-values for priority

## [1.0.0] - 2020-10-02


### Added


- Basic decision tree navigation
