 ## [Unreleased]
 
 ### Changed
+- The special fields like `Printed` and `Read status` now show gray icons when the row is hovered.
+- We added a button in the tab header which allows you to close the database with one click. https://github.com/JabRef/jabref/issues/494
+- Sorting in the main table now takes information from cross-referenced entries into account. https://github.com/JabRef/jabref/issues/2808
+- If a group has a color specified, then entries matched by this group have a small colored bar in front of them in the main table.
+- Change default icon for groups to a circle because a colored version of the old icon was hard to distinguish from its black counterpart.
+- In the main table, the context menu appears now when you press the "context menu" button on the keyboard. [feature request in the forum](http://discourse.jabref.org/t/how-to-enable-keyboard-context-key-windows)

 ### Removed
-
-

+- The feature to "mark entries" was removed and merged with the groups functionality.  For migration, a group is created for every value of the `__markedentry` field and the entry is added to this group.
+- The number column was removed.
+- We removed the coloring of cells in the maintable according to whether the field is optional/required.
+- We removed a few commands from the right-click menu that are not needed often and thus don't need to be placed that prominently:
+  - Print entry preview: available through entry preview
+  - All commands related to marking: marking is not yet reimplemented
+  - Set/clear/append/rename fields: available through Edit menu
+  - Manage keywords: available through Edit menu
+  - Copy linked files to folder: available through File menu
