     CompuMate ROM; this controller type can no longer be manually
     selected, and will be used automatically used for CompuMate ROMs.
 
+	* Fixed cheat codes, so 7 digits codes are now accepted as described in
+	  the doc.
+
+  * Fixed swapped ports being displayed wrong in System Logs and debugger.
+
+	* Added options to erase the AtariVox/Savekey for all ROMs or the current
+	  one.
+
+  * Moved various developer related settings in new Developer Settings
+	  dialog. These settings now come in two groups (player/developer) and
+		allow switching all settings at once.
+
+	* Improved tab auto-complete in debugger
+
+	* Added conditional traps and savestate creation to debugger
+
+	* Extended 'rewind' to take a second parameter which allows rewinding
+	  multiple states.
+
+	* Added 'unwind' command, which undoes the latest rewind(s)
+
+	* Added '<' (unwind) button to debugger.
+
+	* Added 'Options...' button to debugger which gives access to the options
+	  menu during debugging.
+
   * Added debugger pseudo-register '_fcycles', which gives the number of
     CPU cycles that have occurred since the frame started.
 
+  * Added debugger pseudo-register '_cyclesLo' and '_cyclesHi', which give
+    the number of CPU cycles that have occurred since emulation started.
+
   * Extended debugger 'dump' command to take a second argument, indicating
     the end of the range to dump data.
 
+	* Added widgets for trackball and SaveKey/AtariVox controllers
+
   * Improved emulation of 'FE' bankswitch scheme (no user-visible changes,
     but internally the emulation is much more accurate compared to the
     real thing).  Related to this, improved the debugger support for this
