 Supported platforms
 -------------------
+This release has been tested on the following platforms:
+- Ubuntu 15.04 (64 bit) with g++-4.9.2
+- Fedora Core 21 (64 bit) with g++-4.9.2
+- Ubuntu 14.04 (64 bit) with g++-4.8.2
+- Ubuntu 12.04.4 (32/64 bit) with g++-4.6.3
+- CentOS/RHEL 6.6 (64-bit) with g++-4.4.7
+- OS X Yosemite 10.10.3 with Xcode 6.3.1 and Apple LLVM version 6.1.0
+- FreeBSD 10.1-RELEASE (64 bit) with clang-3.4.1
 
 New user-visible features
 -------------------------
 - (network) CalculateTxTime has been declared obsolete.
   CalculateBytesTxTime and CalculateBitsTxTime are to be used instead.
   The return value is a Time, instead of a double.
-- (mobility) Classes for converting geographic to cartesian coordinates.
-- (spectrum) TvSpectrumTransmitter classes to create television 
+- (mobility) Classes added for converting geographic to cartesian coordinates.
+- (spectrum) TvSpectrumTransmitter models added to create television 
   transmitter(s) that transmit PSD spectrums customized by attributes such 
   as modulation type, power, antenna type, channel frequency, etc.
-- (wifi) 802.11n extended to support two-level aggregation.
+- (wifi) Several model improvements have been made.  Access points now 
+  establish BSSBasicRateSet for control frame transmissions.  PLCP header 
+  and payload reception have been decoupled for improved PHY modeling
+  accuracy.  RTS/CTS with A-MPDU is now fully supported, and 802.11n
+  stations now support two-level aggregation.
