 - 2.1.1 (26th September 2014)
 
+* Added new IS_HCP packet and HandicapHelper class.
 * Added ContinueOnCapturedContext property to InSim, TcpSocket and UdpSocket. Setting this to false prevents InSim.NET from marshalling packet callbacks back onto the calling thread e.g. in UI programs.
-* Fixed exploit that allowed players to crash InSim.NET by typing characters in LFS that were not translatable into unicode.
-* Fixed bug where sending certain multibyte characters could cause a crash.
+* Fixed bug that allowed players to crash InSim.NET by typing characters in LFS that were not translatable into unicode.
 * TcpSocket and UdpSocket now expose their underlying .NET Socket objects for convienence.
