What’s new in Anaconda 2.5?

Anaconda 2.5 now includes the Intel Math Kernel Library (MKL) version 11.3.1 for improved performance.

Anaconda now also includes a small utility package called mkl-service which provides a Python interface to some useful MKL functions declared in mkl_service.h, such as setting the number of threads to use.

MKL takes roughly 100MB and some use cases do not need it, so users can opt out of MKL and instead use OpenBLAS for Linux or the native Accelerate Framework for MacOSX. To opt out, run conda install nomkl and then use conda install to install packages that would normally include MKL or depend on packages that include MKL, such as scipy, numpy, and pandas. Conda will install the non-MKL versions of these packages and their dependencies. If you are using OS X or Linux, have already installed these packages or already installed all of Anaconda, and wish to switch away from MKL, use the commands conda install nomkl numpy scipy scikit-learn numexpr and then conda remove mkl.

Anaconda 2.5 also adds Windows debugging information files, adds an option to install on Windows without touching the registry, and includes the OpenSSL security update to OpenSSL version 1.0.2f.
