Version 1.1.1
--------------
- Removed cost_based.LayoutAlgorithmOptions (options are passed directly to the LayoutAlgorithm constructor instead).
Version 1.1.0
--------------
- Implemented a cost-based layout algorithm (Issue #35).
The implementation depends on shapely, which is added as an optional
dependency (package needs to be installed as matplotlib-venn[shapely] for
it to be included).
Thanks to https://github.com/paulbrodersen
- Added a set diagram to the README (Issue #51).
- Fixed doctests that started failing due to different numpy versions representing values differently.
Version 1.0.0
--------------
- Fixed package installation issues (Issue #78).
Version 1.0.0-alpha
--------------
- Dropped support for Python versions below 3.5 (by excluding those versions from CI builds).
- Added typing annotations. Some arguments are now a bit more strictly typed.
E.g. what previously would accept a List now requires (at least as far as type annotations are concerned) a tuple.
- Refactored the code by abstracting away the layout algorithms to allow plug-in customization (Issue #35).
This deprecated the `normalize_to` input argument to the venn2 and venn3 functions, and made
`venn2_unweighted` and `venn3_unweighted` obsolete. These will be removed in some future version.
Version 0.11.10
--------------
- Updated tests to work with Matplotlib 3.6+ (PR#70).
Version 0.11.9
--------------
- Minor update to metadata (mark Development Status as Stable).
Version 0.11.8
--------------
- Added pyproject.toml (Issue #71).
Version 0.11.7
--------------
- Fixed Travis-CI-related error messages.
Version 0.11.6
--------------
- Added matplotlib_venn.__version__ field (Issue #59).
Version 0.11.5
--------------
- Added subset_label_formatter parameter (PR#28).
Version 0.11.4
--------------
- Added support for Counter objects (PR#26).
Version 0.11.3
--------------
- Tiny change in README required a version bump to upload it to PyPi.
Version 0.11.2
--------------
- Fixes issue #24.
- Addresses Debian bug #813782.
Version 0.11
------------
- Fixed issue #17. This would change the previous layout of circles in certain pathological cases.
Version 0.10
------------
- Completely rewritten the region generation logic, presumably fixing all of the problems behind issue #14
(and hopefully not introducing too many new bugs). The new algorithm positions the labels in a different way,
which may look slightly worse than the previous one in some rare cases.
- New kind of IPython-based tests.
Version 0.9
-----------
- Better support for weird special cases in Venn3 (i.e. one circle being completely inside another, issue #10).
Version 0.8
-----------
- Added support for Python 3.
Version 0.7
-----------
- Added the possibility to provide sets (rather than subset sizes) to venn2 and venn3.
Thanks to https://github.com/aebrahim
- Functions won't bail out on sets of size 0 now (the diagrams won't look pretty, though).
Thanks to https://github.com/olgabot
- Venn2/Venn3 objects now provide information about the coordinates and radii of the circles.
- Utility functions added for drawing unweighed diagrams (venn2_unweighted, venn3_unweighted)
- Labels for zero-size sets can be switched off using a method of VennDiagram.
- Some general code refactoring.
Version 0.6
-----------
- Added "ax" keyword to the plotting routines to specify the axes object on which the diagram will be created.
Thanks goes to https://github.com/sinhrks
Version 0.5
-----------
- Fixed a bug (issue 1, "unreferenced variable 's'" in venn2 and venn2_circles)
Version 0.4
-----------
- Fixed a bug ("ValueError: to_rgba: Invalid rgba arg" when specifying lighter set colors)
Version 0.3
-----------
- Changed package name from `matplotlib.venn` to `matplotlib_venn`.
- Fixed up some places to comply with pep8 lint checks.
Version 0.2
-----------
- Changed parameterization of venn3 and venn3_circles (now expects 7-element vectors as arguments rather than 8-element).
- 2-set venn diagrams (functions venn2 and venn2_circles)
- Added support for non-intersecting sets ("Euler diagrams")
- Minor fixes here and there.
Version 0.1
-----------
- Initial version, three-circle area-weighted venn diagrams.
