 * Includes a fix for the common Android 5.0 crash ([#106](https://github.com/EsotericSoftware/kryonet/issues/106), [#120](https://github.com/EsotericSoftware/kryonet/issues/106))
 * The LAN Host Discovery is now available to Non-Kryo-Serializations ([#127](https://github.com/EsotericSoftware/kryonet/issues/127))
 * Kryonet now uses a [gradle](https://gradle.org/) build setup
+* Improved the tests as well as the  code coverage
 * Java 9+ is supported
 * Various improvements to the documentation (also takes care of [#35](https://github.com/EsotericSoftware/kryonet/issues/35), [#44](https://github.com/EsotericSoftware/kryonet/issues/44), [#124](https://github.com/EsotericSoftware/kryonet/issues/124), [#137](https://github.com/EsotericSoftware/kryonet/issues/137))
