 **Version** | **Description**
 --------|------------
+v0.6 | Added an alternative JavaFX-GUI based on FXML to give an example of how the project could be solved using FXML and CSS. To run the FXML-version, run the class **ContactsAppFXML**. This class uses the **ContactsMain.fxml**-file to build the GUI, together with the **ContactsAppFXML.css**-file. The controller used with the FXML-version of the GUI, is the **ContactsAppFXMLController**. <br>NOTE: Using "FXML" as part of the class-names is not a recommended practice, and is only done so in this project to make it clear which of the classes/files are linked to the use of the JavaFx FXML-solution. <br>Also, the existing non FXML-controller class **MainController** has been refactored to take the responsibility for the AddressBook instance (previously managed by the view class **ContactsApp**. <br>And there are also some other minor changes/modifications.
 v0.5.1 | Some minor adjustments: removed *synchronized* from the iterator()-method of ContactDetails (not needed). Updated the ContactDetails-constructor to make use of the set-methods of the class.
 v0.5 | Added support for MySQL-DB at IDI (https://mysql-ait.stud.idi.ntnu.no/phpmyadmin/) through a separate *persistence unit (PU)* in the persistence.xml-file.   NOTE: You must set your own **username**, **password** and **database name**.  Also support has been added for a locally installed Apache Derby Server.
+v0.4.3 | Added support for MySQL-DB at IDI (https://mysql-ait.stud.idi.ntnu.no/phpmyadmin/) through a separate *persistence unit (PU)* in the persistence.xml-file.   NOTE: You must set your own **username**, **password** and **database name**.  Also support has been added for a locally installed Apache Derby Server.
 v0.4.1 | Renamed the class AddressBookDAO to AddressBookDBHandler, since DAO is a general term that also could be used for the AddressBookFileHandler. Also altered slightly the use of EntityManager.
 v0.4 | Added Relational Database support, using the embedded Apache Derby server. For details of the changes made, se below.
 v0.3 | Adds object serialization of the entire address book.
