Link to changelog

Sourced from iminuit's changelog.

2.12.0 (June 21, 2022)

New features

- New cost function ``cost.BarlowBeestonLite`` for template fits with correct uncertainty propagation for templates obtained from simulation or sWeighted data, written together with @AhmedAbdelmotteleb
- Formerly private chi2 utility cost functions (``cost.poisson_chi2``, etc.), are now part of public API
- Support custom grid in ``Minuit.profile``, ``iminuit.mncontour``, ``iminuit.contour``
- Handle common CL values in ``Minuit.mnprofile`` and ``Minuit.mncontour`` without scipy
Fixes
- Skip tests that use ``np.float128`` on platforms where this type is not supported
- ``Minuit.valid`` now returns ``False`` if EDM is NaN
- ``subtract_min`` setting is no longer ignored by ``Minuit.draw_contour``

<li>New study about template fits</li>

</ul>

<p>Other</p>

<pre><code>- Minuit no longer warns when a function is used that has no errordef

attribute and Minuit.errordef is not explicitly set. The function is

assumed to be chi-square-like up to an arbitrary constant, unless errordef

is explicitly set to something else.

More type correctness in API, better hiding of private objects in library
Option to use external pybind11, by @henryiii
Update to pybind11-v2.9.2, by @henryiii
Update to root-v6-25-02 plus our patches
Several minor cleanups and internal tool updates, by @henryiii
