The major new physics feature in this release is the addition of the branching ratio of the rare inclusive B→X_ql⁺l^- (l=e or μ) decay. Many thanks to Tobias Huber for providing analytical expressions and making numerical cross-checks that made the implementation of (most of) the corrections in arXiv:1503.04849 possible. Thanks also to the Munich Institute for Astro- and Particle Physics (MIAPP) for hospitality during this effort.

Another new feature is more cosmetic: metadata have been added to all observables, making it possible to split the list of observables into categories rather than one huge list.

Finally, thanks to Christoph Niehoff for improvements and cross-checks in B_q→l⁺l^-.
