v2.6.1

Measurements

• Updated $b\to u\ell\nu$ and $B$ mixing measurements (thanks to @alekssmolkovic)

Parameters

• Updated SM coupling constants and CKM parameters
• Updated $B\to K$ form factors to those of arXiv:2305.06301

Observables

• Updated Kaon mixing using u-t unitarity based on arXiv:1911.06822
• Fixed small issues in $B\to K^{(\ast)}\nu\nu$ and $K\to \pi^{(\ast)}\nu\nu$ observables
• Updated prediction of $m_W$

Features

• Update and improve error_budget_pie function
• Fixed diff_plot_th_err function to correctly utilize argument N (thanks to @girishky)
• Updated to ckmutil v1.2.0 and implement new $\beta\gamma$ CKM scheme

v2.5.5

This minor release changes the convention used for the $h_{T3}$ HQET form factor from the one of arXiv:1309.0301 to the one of arXiv:1703.05330. This fixes a bug in the implementation of the from factors from arXiv:1908.09398 (which use the convention of arXiv:1703.05330).

In addition, recent LHCb measurements of RD and RD* have been added (thanks to @MJKirk) and the flavio.plots.likelihood_contour_data function has received support for log scale grids.

v2.5.4

This minor release adds additional sources of uncertainties to the theory predictions of super-allowed beta decays (thanks to @MJKirk)

v2.5.3

This minor release raises the minimum required version of particle to 0.21.0 to make sure that the PDG 2022 data is available

v2.5.2

This minor release updates several measurements and input parameters:

• measurements and input parameters related to the Cabibbo angle anomaly (CAA) are updated to those used in arXiv:2212.06862 (thanks to @MJKirk)
• PDG input parameters are updated to the 2022 version (thanks to @MJKirk)
• K+->pinunu measurement by NA62 from 2021 is added

v2.5.1

This minor release adds missing package_data in setup.py.

In addition, the $B\to\ell\nu$ measurements have been updated (thanks to @alekssmolkovic )

v2.5.0

New observables

• The high-mass neutral current ($pp \to \ell \ell$) and charged current ($pp \to \ell \nu$) Drell-Yan differential cross-section predictions and experimental data as described in arXiv:2212.10497 (thanks to @alekssmolkovic and @jsalko)
• LFV quarkonium decays as described in arXiv:2207.10913 (thanks to @micha-a-schmidt)
• Several $b\to d\ell\ell$ observables used in measurements by Belle and LHCb (thanks to @alekssmolkovic)

New measurements

• $B_s\to \mu\mu$ measurement by CMS from 2022 and a combination with the LHCb and ATLAS measurements done in arXiv:2212.10497
• The new and update measurements of $R_K$ and $R_{K^*}$ by LHCb from 2022

New and updated input parameters

• $B_d$ and $B_s$ bag parameters for meson mixing as described in arXiv:2212.10497
• $B\to \pi$ form factors from arXiv:2102.07233 (thanks to @alekssmolkovic)

Bug fixes and code improvements

• Several probability distributions based on the Gamma distribution have been implemented in a more consistent way and previous issues have been fixed
• Several issues in the definition of the $B\to D$ and $B\to D^*$ HQET form factors have been fixed

v2.4.0

New observables

• A large number of observables (decay widths and angular observables) of the decay Λ_b→Λ(1520)ll has been added, including two different form factor implementations (thanks to @Felicia56)

Measurements

• The LHCb B->ee 2020 measurement has been implemented using the Gaussian uncertainties provided in the LHCb paper instead of upper bounds, which allows it to be used in a FastLikelihood (thanks to @alekssmolkovic)

Bug fixes

• In the computation of epsilon_K, an issue with the renormalization scales of quark masses has been resolved (thanks to @MJKirk)
• An issue with labels in contour plots when using a matplotlib version >= 3.5.0 has been fixed (thanks to @MJKirk)
• The complex phase in the CKM dependence of the K→πνν amplitude has been fixed
• Deprications in numpy that expired in numpy 1.23 and 1.24 have been fixed

v2.3.3

This minor release adds the recent LHCb measurements of R(KS) and R(K*+) from arXiv:2110.09501 (thanks to @nsahoo).

v2.3.2

This is a bug fix release that makes flavio compatible with the interface of particle v0.20.0.
