+Summary of changes in 2020.12
+
+* libbladeRF
+    - Added packet mode format BLADERF_FORMAT_PACKET_META. libbladeRF is able to
+      exchange variable length packets with the HDL if packet mode is enabled
+    - Added RFIC parameters for burst waveforms
+    - Ability to query backend for handle and lock
+
+* FX3
+    - Variable length packet support for PACKET_META mode
+
+* bladeRF-cli:
+    - Indicate presence of packet cores in FPGA
+
+* FPGA:
+    - Add packet mode. The HDL fabric is able to exchange variable length
+      packets with the host
+    - Added packet_generator as an example for how to send packets to the host
+    - Added bladeRF 2.0 micro headless example variant "foxhunt"
+    - Fix metadata related arithmetic and logic
+
+* Python
+    - Update for libbladeRF v2.4.0
