Hi all,
KLEE 1.4.0 is now available at
https://github.com/klee/klee/releases/tag/v1.4.0
Lots of new changes, in particular a new CMake build system, support for
some missing features for LLVM 3.4 (and partial support for 3.5 and
3.6), better support for MacOS, support for release documentation (as in
http://klee.github.io/releases/docs/v1.4.0/) and many other
optimizations, features and bug fixes.
KLEE 1.4.0 will be the last version to support LLVM 2.9 and the autoconf
build system, which should enable us to more easily implement new
features. So please start configuring KLEE to use LLVM 3.4 and CMake,
if you haven't done this already.
Many thanks for all the contributions!
Cristian
