-----------------------

Other
~~~~~
- Fixed wording in cost function tutorial

-----------------------

Fixes
~~~~~
- Fixed a failure of ``util.make_with_signature`` in some situations

Other
~~~~~
- Raise numpy.VisibleDeprecationWarning instead of warnings.DeprecationWarning
- ``util.propagate`` is deprecated in favour of ``jacobi.propagate`` from the jacobi library

-----------------------

New features
~~~~~~~~~~~~
- All builtin cost functions now support multidimensional data
- ``Matrix.to_dict`` was added for symmetry with ``BasicValueView.to_dict``
- For long-running fits, total runtime is now shown in ``FMin`` display and total runtime can be accessed via property ``FMin.time``

Fixes
~~~~~
- In binned fits when ``ndof`` is zero, show ``reduced chi2 = nan`` in the ``FMin`` display instead of raising a ZeroDivisionError

Documentation
~~~~~~~~~~~~~
- Tutorials and studies are now listed separately
- Tutorial for fits of multivariate data were added
- The cost function tutorial was improved
- Studies in regard to performance were added, including a comparison with RooFit

----------------------

New features
~~~~~~~~~~~~
- ``UnbinnedNLL`` and ``ExtendedUnbinnedNLL`` now support models that predict the
``logpdf`` instead of the ``pdf`` when the extra keyword ``log=True`` is set; when
it is possible, using the ``logpdf`` instead of the ``pdf`` for fitting is faster
and numerically more stable

-----------------------

Fixes
~~~~~
- ``Minuit.draw_mncontour`` now works with matplotlib >= 3.5
- Builtin cost functions now work correctly when the mask is set and data is updated on
the existing cost function

Performance
~~~~~~~~~~~
- Builtin cost functions are now more performant when used with weighted binned data

Other
~~~~~
- Wheels for Python 3.10, by henryiii
- Bump pybind11 to 2.9.0, by henryiii

------------------------

Fixes
~~~~~
- Pickling of ``util.Matrix`` resulted in incomplete state after unpickling, which would
cause an exception when you tried to print the matrix

Documentation
~~~~~~~~~~~~~
- New tutorial on fitting PDFs that depend on a conditional variable
- Fixed JAX tutorial, adapting to change in their interface
- Extended documentation of cost functions
