         * VCC3V3 Auto Track pin is connected to VCC5V0. VCCINT Auto Track pin is connected to VCC3V3
   * Mutant WSCA/SYNC signal is now on a CC pin
+  * Footprint updates
+    * (U36), (U38), and (U39) Switching regulators have updated hole sizes for better fitting
+    * (SW2) HDT001 switch layout fixes
+  * Changed Clocking (see [[cobo_clocking|CoBo Clocking]])
+    * CKRs traces from PLL to LVDS buffer and from LVDS buffer to VHDCI connector are now equal
+    * CKWs traces from PLL to LVDS buffer and from LVDS buffer to VHDCI connector are now equal
+    * On LMK04800 (U41) CLKin1 no longer uses MCH clock as an input. A dedicated oscillator is now used (X9)
