+Build system changes
+--------------------
+
+- In wxMSW makefile builds, "_x64" is used instead of "_amd64" when compiling
+ for this architecture in the architecture-specific paths and library names.
+ TARGET_CPU can still be specified as "amd64" for compatibility but "x64"
+ should be used now.
+
+- Official wxMSW binaries, i.e. those built with OFFICIAL_BUILD=1, built with
+ MSVC now include the version of the compiler used and the architecture if
+ it's not the default "x86". E.g. a library built with MSVC 10 for amd64 is
+ called "wxbase294ud_vc110_amd64.dll" now.
