 \b The script compiler, makensis, builds and works on big-endian platforms. This change enlarges the portability range of NSIS to theoretically every POSIX platform. Please \W{http://sourceforge.net/tracker/?group_id=22049&atid=373085}{report} any incompatibility with specific platforms or build-tools.
 
-\b The internal changes made to support big-endian platforms also pave the road to x64 installers. There is now a central function which writes data to disk. This function currently only converts the endianity of integers, but it can be changed to selectively write 64-bit integers. Hopefully, there'll soon be a simple method of compiling a script to both x86 and x64 installers.

 \b Changing Source/exehead/fileform.h to alter the internal structure of installers is no longer enough. The compiler has its own definitions of the structures which must also be changed in Source/fileform.cpp. In the future, fileform.cpp should be automatically generated from fileform.h, but for now, the synchronization must be done manually.
