+ndn-cxx version 0.6.2
+---------------------
+
+Release date: May 4, 2018
+
+Note that this is the last release that encodes to [NDN packet format version
+0.2.1](https://named-data.net/doc/NDN-packet-spec/0.2.1/). A future release will continue to
+decode v0.2.1 format, but will encode to [v0.3
+format](https://named-data.net/doc/NDN-packet-spec/0.3/).
+
+New features:
+^^^^^^^^^^^^^
+
+- Initial support for [NDN packet format version
+  0.3](https://named-data.net/doc/NDN-packet-spec/0.3/) (:issue:`4527`)
+
+  * Recognize typed name components, allow typed name component in ``FinalBlockId``
+    (:issue:`4526`)
+
+  * Recognize Interest in Packet Format v0.3 (:issue:`4527`)
+
+    In this release, ``Interest::wireDecode`` accepts both v0.2 and v0.3 formats, but
+    ``Interest::wireEncode`` only encodes into v0.2 format. A future release of the
+    library will switch the encoding to v0.3 format.
+
+  * Recognize Data in Packet Format v0.3 (:issue:`4568`)
+
+    In this release, ``Data::wireDecode`` accepts both v0.2 and v0.3 formats, but
+    ``Data::wireEncode`` only encodes into v0.2 format. A future release of the library
+    will switch the encoding to v0.3 format.
+
+- Library support for cs/erase command of NFD Management (:issue:`4318`)
+
+- A convenience function to print out ``Block`` structures (:issue:`2225`)
+
+Improvements and bug fixes
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Change encoding of NDNLPv2 sequence number from nonNegativeInteger to fixed-width
+  integer (8 bytes in network order) (:issue:`4403`)
+
+- Fix compilation with Boost 1.67 (:issue:`4584`)
+
+- Upgrade build environment to latest version of ``waf`` and other improvements
+
+- Logging system improvements (:issue:`4552`)
+
+Deprecated
+~~~~~~~~~~
+
+- Selectors (:issue:`4527`)
+
+  NDN Packet Format v0.3 replaces Selectors with ``CanBePrefix`` and ``MustBeFresh`` elements.
+  This commit deprecates getter/setter for Selectors in Interest class. Getter/setter for
+  CanBePrefix and MustBeFresh are mapped to the closest v0.2 semantics and encoded as
+  selectors.
+
+- ``Data::get/setFinalBlockId()`` in favor of ``Data::get/setFinalBlock()``
