• adding initial formulas for the LCSR of the B→ π form factor f₀;
• adding support for forward-folded multivariate Gaussian constraints through a response matrix;
• adding the eos-analysis script to replace the current C++ clients in the long run;
• building Python binaries for CPython 3.6, 3.7 and 3.8 for linux-x86_64-gnu;
• disabling the GSL default error handler when loading libeos.so;
• fixing syntax problems in the documentation.

Installing from the Python Package Index (PyPI)

The current master branch has just been updated with changes that allow to automatically build and deploy EOS to the Python Package Index. Binaries (so-called ‘wheels’) corresponding to version 0.3.1+ have been uploaded there, supporting the manylinux2014_x86_64 platform with CPython versions 3.6, 3.7 and 3.8. If you are running Linux with one of these Python versions, feel free to give the pre-buit EOS a try:

pip3 install eoshep

The Python interface to EOS is documented here. Binaries built against more recent CPython versions will be made available once the Python Packaging Authority (PyPA) updates their docker image.

Many thanks to Martin Ritter for both technical and moral support in adding this feature!
