+New user-visible features
+-------------------------
+- It is now possible to print the Neighbor Cache (ARP and NDISC) by using
+  the RoutingProtocolHelper
+- In previous releases of the LTE module, the bearer release
+  functionality was only partially supported. As an enhancement, a
+  complete release bearer procedure is now implemented, which can be
+  invoked by calling the new helper method
+  LteHelper::DeActivateDedicatedEpsBearer(). The related output can be
+  seen through the stats collected at different layers like PDCP, RLC,
+  MAC, PHY. To support this implementation, example and test suite is
+  added within the LTE module examples and tests folder.

+Release 3.21
+============
+
+Availability
+------------
+This release is available from:
+http://www.nsnam.org/release/ns-allinone-3.21.tar.bz2
+
+Supported platforms
+-------------------
+- Fedora Core 20 (32/64 bit) with g++-4.8.2
+- Ubuntu 14.04 (32/64 bit) with g++-4.8.2
+- Ubuntu 12.04.4 (64 bit) with g++-4.6.3
+- Ubuntu 10.04.4 LTS (64 bit) with g++-4.4.3
+- CentOS/RHEL 6.5 (64-bit) with g++-4.4.7
+- OS X Mavericks 10.9 with Xcode 5.1.1 and clang-503.0.40
+- FreeBSD 9.2-RELEASE (64 bit) with clang-3.3

+New user-visible features
+-------------------------
+
+- The LTE module now supports the transport of the S1-U, X2-U and X2-C
+  interfaces over emulated links via the new helper class EmuEpcHelper.
+- CommandLine can now provide a shorthand argument name for any
+  Attribute.
+- Implemented support for Frequency Reuse algorithms in LTE module, as the 
+  outcome of GSoC 2014 project. 
+  The project also includes several sub-features, such as:
+   - implementation of Downlink Power Control
+   - implementation of Uplink Power Control
+   - new DL-CQI generation approach, which increases throughput if FR algorithms 
+     are used
+   - seven options of Frequency Reuse algorithms: LteFrNoOpAlgorithm, 
+     LteFrHardAlgorithm, LteFrStrictAlgorithm, LteFrSoftAlgorithm, 
+     LteFfrSoftAlgorithm, LteFfrEnhancedAlgorithm, LteFfrDistributedAlgorithm
+   - updated RadioEnvironmentMapHelper. Now RadioEnvironmentMap can be generated 
+     for Data or Control channel and for specified RbId, what is helpful when 
+     using FR algorithms
+- Added a CoDel queue model.  CoDel queues measure and control the queue
+  traversal delay.  The ns-3 implementation is a port of the Linux 
+  implementation.
+- Added support for TCP timestamp and window scale options, and added
+  ability to trace the TCP slow start threshold value.
+- SimpleNetDevice and SimpleChannel (used for adding basic link effects
+  for testing of higher-layer protocols) have been extended to support 
+  the option of broadcast or PointToPoint link semantics.  The bandwidth
+  and link delay can be constrained, and it uses an output queue.
+- SimpleNetDevice and SimpleChannel can be installed in a node through 
+  a new helper: SimpleNetDeviceHelper.
+- Implemented new PacketSocketServer and PacketSocketClient applications.
+  The primary use is in tests, to avoid using the ones from the 
+  application module that also bring in a dependency on the internet module.

+- Bug 1951 - AODV does not update nexthop for 1-hop nodes
+- Bug 1955 - The IPv4 identification field should be unique per (source, destination, protocol) tuple
+- Bug 1960 - Wrong information on index range, about Node::GetDevice
+- Bug 1961 - planetlab-tap-creator "variable set but not used"
+- Bug 1963 - AODV can tag the same packet twice (and raise an assert)
+- Bug 1964 - Integer overflow on UniformRandomVariable::GetInteger()
+- Bug 1967 - LL Multicast is not compressed in the right way in IPHC

+
+Known issues
+------------
+- Bug 1770 - The mesh module will crash if used for g++ version >= 4.8.1
+in optimized mode, on a 32-bit Linux machine.  Lowering the optimization
+level to -O1 in this case can be used as a workaround.
