 # [unreleased]
 
+## Changed
+
+- The CCSDS IP core handler now exposes a parameter to enable the priority select mode
+  for the PTME core. This mode prioritizes virtual channels with a lower index, so for example
+  the virtual channel (VC0) will have the highest priority, while VC3 will have the lowestg
+  priority. This mode will be enabled by default for now, but can be set via the parameter IF with the unique
+  parameter ID 0. The update of this mode requires a PTME reset. Therefore, it will only be performed
+  when the transmitter is off to avoid weird bugs.
