+	* apps/examples/alarm: ioctl call was clobbering file descriptor
+	  (2016-06-02).
 	* apps/system/flash_eraseall:  Removed!  This logic violates the OS/
 	  application interface and cannot be supported.  The old code can still
 	  be found in the 'Obsoleted' repository (2016-06-03).
-
+	* apps/fsutils/flash_eraseall: IOCTL wrapper for MDCIO_BULKERASE command
+	  (2016-06-04).
+	* apps/system/flash_eraseall: Restored!  Using the new IOCTL wrapper at
+	  apps/fsutils/flash_eraseall (2016-06-04).
+	* apps/canutils/libuavcan: Fix for recent change to STM32 timer frequency
+	  definiitions (2016-06-05).
