      =========================================================
 
+* **Added non-EAL threads registration API.**
+
+  Added a new API to register non-EAL threads as lcores. This can be used by
+  applications to have its threads known of DPDK without suffering from the
+  non-EAL previous limitations in terms of performance.
+
+* **rte_*mb APIs are updated to use DMB instruction for ARMv8.**
+
+  ARMv8 memory model has been strengthened to require other-multi-copy
+  atomicity. This allows for using DMB instruction instead of DSB for IO
+  barriers. rte_*mb APIs, for ARMv8 platforms, are changed to use DMB
+  instruction to reflect this.
+
+* **Added the support for vfio-pci new VF token interface.**
+
+  From Linux 5.7, vfio-pci supports to bind both SR-IOV PF and the created VFs,
+  it uses a shared VF token (UUID) to represent the collaboration between PF
+  and VFs. Update DPDK PCI driver to gain the access to the PF and VFs devices
+  by appending the VF token parameter.
+
+* **Added the RegEx Library, a generic RegEx service library.**
+
+  Added the RegEx library which provides an API for offload of regular
+  expressions search operations to hardware or software accelerator devices.
