+# Changelog
+
+## [2.3.1] - 2019-11-04
+
+### Added
+
+* `CHANGELOG` added.
+* `onDedicated` method that determines if the current environment is a Platform.sh Dedicated environment. Replaces deprecated `onEnterprise` method.
+
+### Changed
+
+* Deprecates `onEnterprise` method - which is for now made to wrap around the added `onDedicated` method. `onEnterprise` **will be removed** in a future release, so update your projects to use `onDedicated` instead as soon as possible.
+
+## [2.3.0] - 2019-09-19
+
+### Added
+
+* `getPrimaryRoute` method for accessing routes marked "primary" in `routes.yaml`.
+* `getUpstreamRoutes` method returns an object map that includes only those routes that point to a valid upstream.
+
+## [2.2.2] - 2019-04-29
+
+### Changed
+
+* Updates `routes` method to use `routesDef` instead of `variablesDef` while checking if routes are defined in a Platform.sh environment.
+* Updates `getRoute` method documentation in `README`.
+
+### Removed
+
+* Guard on the `variables` method.
+
+## [2.2.1] - 2019-04-25
+
+### Changed
+
+* Improved the error handling for missing property variables.
+
+## [2.2.0] - 2019-04-24
+
+### Changed
+
+* Route URL addition moved to constructor.
+* Switch to more permissive checking of variable availability.
+
+## [2.1.0] - 2019-03-22
+
+### Added
+
+* Adds `hasRelationship` method, which determines if a relationship is defined, and thus has credentials available.

+> **Note:**
+>
+> Platform.sh will no longer refer to its [99.99% uptime SLA product](https://platform.sh/solutions/) as "Enterprise", but rather as "Dedicated". Configuration Reader libraries have in turn been updated to include an `onDedicated` method to replace `onEnterprise`. For now `onEnterprise` remains available. It now calls the new method and no breaking changes have been introduced.
+>
+> It is recommended that you update your projects to use `onDedicated` as soon as possible, as `onEnterprise` will be removed in a future version of this library.

 Credential Formatters can be registered on the configuration object, and a few are included out of the box.  That allows 3rd party libraries to ship their own formatters that can be easily integrated into the `Config` object to allow easier use.
