+* **Added IPsec Library.**
+
+ Added an experimental library ``librte_ipsec`` to provide ESP tunnel and
+ transport support for IPv4 and IPv6 packets.
+
+ The library provides support for AES-CBC ciphering and AES-CBC with HMAC-SHA1
+ algorithm-chaining, and AES-GCM and NULL algorithms only at present. It is
+ planned to add more algorithms in future releases.
+
+ See :doc:`../prog_guide/ipsec_lib` for more information.
+
+* **Updated the ipsec-secgw sample application.**
+
+ The ``ipsec-secgw`` sample application has been updated to use the new
+ ``librte_ipsec`` library also added in this release.
+ The original functionality of ipsec-secgw is retained, a new command line
+ parameter ``-l`` has been added to ipsec-secgw to use the IPsec library,
+ instead of the existing IPsec code in the application.
+
+ The IPsec library does not support all the functionality of the existing
+ ipsec-secgw application, its is planned to add the outstanding functionality
+ in future releases.
+
+ See :doc:`../sample_app_ug/ipsec_secgw` for more information.
