+Release 2.7
+-----------
+
+Release date: February 24, 2019
+
+Overview
+~~~~~~~~
+
+- The submodules of NFD and ndn-cxx have been upgraded to version 0.6.5.
+
+  `NFD 0.6.5 release notes <https://named-data.net/doc/NFD/0.6.5/RELEASE_NOTES.html>`__
+
+  `ndn-cxx 0.6.5 release notes <https://named-data.net/doc/ndn-cxx/0.6.5/RELEASE_NOTES.html>`__
+
+    .. note::
+       In order to retrieve the marked versions of ndn-cxx and NFD, use
+       ``--recursive`` option to the git clone command or run ``git
+       submodule update --init`` after clone, pull, or merge.
+
+- Base NS-3 was rebased to version 3.29
+
+- Following changes in NFD and ndn-cxx codebases, the build requirements have been upgraded to gcc
+  >= 5.3 or clang >= 3.6, boost >= 1.58, openssl >= 1.0.2. This effectively drops support for all
+  versions of Ubuntu older than 16.04 that use distribution-provided compilers and packages.
+
+- The compilation now uses the C++14 standard.
+
+Improvements and bug fixes
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+- Update face metric based on simulated p2p link delay (:issue:`4733`)
+
+- Remove and replace the previously deprecated and removed in NS-3.29 ``QueueBase::MaxPackets``
+
+- Update installation instructions
+
+Deprecation
+~~~~~~~~~~~
+
+- ndnSIM 2.7 is the last release that supports the legacy content store implementation.  The future versions
+  will only include content store replacement/placement policies implemented using NFD routines.  Please
+  refer to the latest version of NFD Developer's Guide for more information.
