kafe release 1.3.3

This is a maintenance release that addresses the incompatibility between kafe and iminuit 2.0 or later.
Running with recent iminuit versions now prompts users to downgrade to 1.5.4.

kafe release 1.3.2

This release fixes a number of small issues, mainly related to changes/deprecations in the matplotlib API.

Changes

• FIX: ensure backend fallback mechanism remains active
  despite explicit call to matplotlib.use, which otherwise leads
  to failures if the backend is not available (or when running in
  headless mode)
• FIX: move imports of matplotlib.pyplot to plot methods to avoid
  importing them prematurely
• FIX: handle deprecation of axis suffixes for keyword arguments
  passed to constructors of axis scale objects starting with
  matplotlib 3.3.0 (e.g. now specify base instead of
  basex/basey for LogScale)
• FIX: replace call to inverse_transformed completely
  by equivalent transformed(transform.inverted())
• FIX: use Legend.set_draggable(True) and fall back to deprecated
  Legend.draggable() on failure for backwards compatibility.

Bugfix release

Some output files were empty when running under Python 3. This version provides a hotfix
by forcing line-buffering on output streams and adding flush() and close() commands
where appropriate.

kafe release 1.3.0

New features

• now runs with both Python 2 and 3 (many thanks to @smartsammler)
• can do multi-model fits with shared parameters (module Multifit by @JoergSchindler)

Fixes and improvements

Some bugs were fixed and compatibility with other tools has been improved:

• kafe now works in Jupyter Notebooks

• fix compatibility issue with matplotlib 2.0

• revise minimum recommended versions for scipy, numpy and iminuit modules

• drop requirement for Qt/PyQt due to difficulties in getting it to work with conda

  • Tk is now the default backend for matplotlib

• better output stream management (fails gracefully when redirection is unsupported, instead of crashing)
