ispc 1.4.2 is Released
----------------------
A minor update of ``ispc`` has been released with stability fix for AVX2
(Haswell), fix for Win32 platform and performance improvements on Xeon Phi.
As usual, it's available on all supported platforms (Windows, Linux and MacOS).
This version supports LLVM 3.1, 3.2, 3.3 and 3.4, but now we are recommending
to avoid 3.1, as it's known to contain a number of stability problems and we are
planning to deprecate its support soon.
The released binaries are built with 3.3.
ispc 1.4.1 is Released
