# Changelog

<!-- %% CHANGELOG_ENTRIES %% -->
## 1.14.1 - 2024-07-29
* use `isEnabled` for serlialized overrides instead of `enabled`

## 1.14.0 - 2024-07-29

* Add `Unleash.Propagation.Serialization.serialize_context!/1` and
  `Unleash.Propagation.Serialization.serialize_overrides!/1`.

  These new methods can be invoked by users of the SDK to further propagate context
  and overrides when sending requests to downstream services.

## 1.13.0 - 2024-07-29
* Introduce the Propagation mechanism

  The propagation mechanism allows to set overrides and context values that will be considered
  whenever a feature state is evaluated (via `enabled/3` or `get_variant/3`) in the current
  or descendant processes.
  The SDK includes two new Plugs that can be used in your Plug-based application
  to automatically extracts overrides and context out of incoming HTTP request headers
  and store them in the Propagation mechanism.

* Support for both string keys and atom keys in context `properties`.

  Previously the SDK would expect a context's `:properties` field to be a map with atom keys.
  (though this expectation wasn't enforced nor specified anywhere).

  With the new propagation mechanism, arbitrary properties can be set from HTTP requests.
  The SDK stores them as string keys instead of doing a potentially dangerous
  runtime conversion of dynamic data to atoms.

  **This is a potentially breaking change if your application relied on properties
  with string values being ignored by the SDK** (which is unlikely).

  A new function `Unleash.find_in_context/2` has been introduced to consistently
  lookup values in a context, which handles fallback to `:properties` and the string/atom dichotomy.

## 1.12.0 - 2024-07-23
* Tune retry behaviour of HTTP requests to Unleash API server.
  They are now only retried once after 50ms, instead of the default `Req` behaviour of retrying 3 times after 1s, 2s, 4s.
* Silence warnings on `Req` retries.
* Log an error when failing to contact the Unleash API server (after retry).

## 1.11.0 - 2024-07-19
* Avoid failing and crashing in case of missing or invalid bootstrap/backup file.
* Load bootstrap/backup file synchronously on startup.
* Do not read the backup file on server errrors. Keep using the local cache instead, which we assume to be in-sync with the backup file, as they bot get udpated whenever we obtain fresh features from the server.
