SciPy 1.2.0 Release Notes

SciPy 1.2.0 is the culmination of 6 months of hard work. It contains
many new features, numerous bug-fixes, improved test coverage and better
documentation. There have been a number of deprecations and API changes
in this release, which are documented below. All users are encouraged to
upgrade to this release, as there are a large number of bug-fixes and
optimizations. Before upgrading, we recommend that users check that
their own code does not use deprecated SciPy functionality (to do so,
run your code with python -Wd and check for DeprecationWarning s).
Our development attention will now shift to bug-fix releases on the
1.2.x branch, and on adding new features on the master branch.

This release requires Python 2.7 or 3.4+ and NumPy 1.8.2 or greater.

Note: This will be the last SciPy release to support Python 2.7.
Consequently, the 1.2.x series will be a long term support (LTS)
release; we will backport bug fixes until 1 Jan 2020.

For running on PyPy, PyPy3 6.0+ and NumPy 1.15.0 are required.

Highlights of this release

• 1-D root finding improvements with a new solver, toms748, and a new
  unified interface, root_scalar
• New dual_annealing optimization method that combines stochastic and
  local deterministic searching
• A new optimization algorithm, shgo (simplicial homology
  global optimization) for derivative free optimization problems
• A new category of quaternion-based transformations are available in
  scipy.spatial.transform

New features

scipy.ndimage improvements

Proper spline coefficient calculations have been added for the mirror,
wrap, and reflect modes of scipy.ndimage.rotate

scipy.fftpack improvements

DCT-IV, DST-IV, DCT-I, and DST-I orthonormalization are now supported in
scipy.fftpack.

scipy.interpolate improvements
