It's okay on julia-users, but don't cc julia-news on replies to announce threads.
We changed the openblas library name, you can fix this by make -C deps distclean-openblas distclean-arpack distclean-suitesparse Apologies for the inconvenience of the rebuild. This should fix some conflicting blas symbol segfaults that have been plaguing pycall/pyplot since they started using Conda.jl. Aside from the rebuild, only a handful of packages that need to compile C libraries that link against julia's custom build of openblas should notice a difference here.
