-## [4.0.0]
-
-See changelog summary under https://github.com/eclipse/lyo/releases/tag/v4.0.0 
-
-### Added
-
-- [Core] Support for abstract types by [@neormx](https://github.com/eclipse/lyo.core/pull/29).
-- [Client] Constants for OSLC version (`OSLCConstants#OSLC{2_0,2_1,3_0}`) and a ctor argument for the new `OslcClient`.
-- [TRS/Server] Unit tests are added based on the Jersey test library and Grizzly embedded server.
-
-### Changed
-
-- [Core] **Switch to JAX-RS 2.**
-- [Core] Only arrays returned from JAX-RS methods annotated with
-`@OslcQueryCapability` will be automatically treated as OSLC Query results
-unless the returned array type is annotated with the
-`@OslcNotQueryResult` ([#88](https://github.com/eclipse/lyo.core/pull/88)).
-- [Core] A checked `LyoJenaModelException` was replaced with an unchecked `LyoModelException`.
-- [Client] JEEFormAuthenticator catches ProcessingException when closing the connection from last redirect
-- [Server] `HTTPConstants` is no longer a public class
-- [Server] `ServletListener` was renamed to `OAuthServletListener`
-- [TRS/Server] `ChangeHistories` has been extracted to the `PagedTrs` interface and the implementing class has been renamed to `InmemPagedTrs`.
-- [TRS/Server]`TrackedResourceSetService` is no longer abstract (still extendable).
-  - `TrackedResourceSetService` supports constructor dependency injection of the `IChangeHistories` instance.
-  - You can still extend it and override `getChangeHistories()` returning an instance of `SimpleChangeHistories` to get the same behaviour as in the earlier release.
-- [TRS/Server] `TrackedResourceSetService` always has a `@Path("/trs")` (because it's hardcoded in other places).
-
-
-### Deprecated
-
-- [Core] **JSON4J** has been deprecated in 2.x but is kept to maintain backwards compatibility. Jena provider is recommended together with the JSON-LD to serve JSON to OSLC Clients.
-- [Store] `JenaTdbStoreImpl` has been lagging behind in functionality and will be deprecated in this release. `StoreFactory#inMemory` and `StoreFactory#onDisk` are also deprecated as they rely on this implementation. *Use `SparqlStoreImpl#SparqlStoreImpl(JenaQueryExecutor)` to pass a `DatasetQueryExecutorImpl` instance instead.*
-
-### Removed
-
-- [Core] Extra MIME type restrictions on top of the ones enforced by the JAX-RS framework ([#22](https://github.com/eclipse/lyo.core/pull/22))
-- [Core] Retired Apache Wink components.
-
-### Fixed
-
-- [Core] regression when `pathParameterValues` are not used ([#66](https://github.com/eclipse/lyo.core/pull/66))

 ## [3.0.0] - SKIPPED
 
 > Where is Lyo 3.0? There was a Lyo 3.0.0-SNAPSHOT development effort long time ago, which has been since abandoned and merged into Lyo 2.2. Furthermore, next version of OSLC will be OSLC 3 and Lyo 3 might mislead users that it adds OSLC 3 support.
