+ndn-cxx version 0.6.6
+---------------------
+
+Release date: April 27, 2019
+
+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:
+^^^^^^^^^^^^^
+
+- More support for `NDN packet format version
+  0.3 <https://named-data.net/doc/NDN-packet-spec/0.3/>`__ (:issue:`4527`)
+
+  * Support new naming conventions to encode/decode segment numbers, byte offsets, versions,
+    timestamps, and sequence numbers based on typed name components (:issue:`4777`)
+
+  * Stop using ``ChildSelector`` in ``CertificateBundleFetcher``  (:issue:`4665`)
+
+- ``NDN_THROW`` macro to throw exceptions including file position and runtime context of the
+  throw statement (:issue:`4834`)
+
+- Ensure that a ``Block`` with TLV-TYPE zero is treated as invalid (:issue:`4726`, :issue:`4895`)
+
+Improvements and bug fixes
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+- Avoid directly using memory address as ``PendingInterestId`` to prevent potential false
+  removal of an entry (:issue:`2865`)
+
+- Follow up packet specification changes to rename the ``Parameters`` element to
+  ``ApplicationParameters`` and to change its number to be a non-critical element type
+  (:issue:`4658`, :issue:`4780`)
+
+- Add option to disable infrastructure interest in ``CertificateFetcherDirectFetch`` (:issue:`4879`)
+
+- Fix compilation against recent versions of Boost libraries and issues with Xcode 10.2 and
+  older versions of Boost libraries (:issue:`4890`, :issue:`4923`, :issue:`4860`)
+
+- Improve the "CanBePrefix unset" warning (:issue:`4581`)
+
+- Improve documentation
+
+Deprecated
+~~~~~~~~~~
+
+- ``PendingInterestId``, ``RegisteredPrefixId``, and ``InterestFilterId`` types in favor of
+  ``PendingInterestHandle``, ``RegisteredPrefixHandle``, and ``InterestFilterHandle``
+  (:issue:`4316`, :issue:`3919`)
+
+- ``Block::empty`` in favor of ``Block::isValid`` (with inverted semantics)
+
+- ``Scheduler::scheduleEvent`` and ``Scheduler::cancelEvent`` in favor of ``Scheduler::schedule``
+  and ``EventId::cancel`` (or use ``ScopedEventId`` to automatically cancel the event when
+  the object goes out of scope) (:issue:`4883`)
+
+- ``ndn::util::Scheduler`` (use ``ndn::Scheduler`` or ``ndn::scheduler::Scheduler``) and
+  ``ndn::EventId`` (use ``ndn::scheduler::EventId``) (:issue:`4883`)
