 ## 1.0.0-beta.2 (Unreleased)
 
+### Features Added
+
+- Added new properties to allow easier interaction with other docker tools:
+  - `loginServer` in `ContainerRegistryClient`.
+  - `fullyQualifiedName` in `ContainerRepository`
+
+### Breaking Changes
+
+The public API surface of this library has been re-designed. Notable changes include
+
+- Removed: `ContainerRepositoryClient`. Operations on repositories are now grouped in `ContainerRepository` type and operations on artifacts are now in `RegistryArtifact` type. Some `*Options` types are also renamed accordingly.
+- Renamed: `endpoint` property is renamed to `registryUrl`.
+- Renamed: `listRepositories()` is renamed to `listRepositoryNames()` in `ContainerRegistryClient`.
+- Renamed: "RegistryArtifact" in property or function names replaced by "Manifest".
+- Renamed: `*OrderBy` values is now capitalized as `timeDesc` and `timeAsc`. Previously they are all in lower case.
