Version 1.3.0

Since the last release we closed over 34 issues and have made 380 commits mostly focused on fixing bugs, cleaning up the API and working extensively on the plotting and rendering system to ensure HoloViews is fully backend independent.

We'd again like to thank our growing user base for all their input, which has helped us in making the API more understandable and fixing a number of important bugs.

Highlights/Features:

• Allowed display of data structures which do not match the recommended nesting hierarchy (67b28f3, fbd89c3).
• Dimensions now sanitized for .select, .sample and .reduce calls (6685633, 00b5a66).
• Added holoviews.ipython.display function to render (and display) any HoloViews object, useful for IPython interact widgets (0fa49cd).
• Table column widths now adapt to cell contents (be90a54).
• Defaulting to matplotlib ticking behavior (62e1e58).
• Allowed specifying fixed figure sizes to matplotlib via fig_inches tuples using (width, None) and (None, height) formats (632facd).
• Constructors of Chart, Path and Histogram classes now support additional data formats (2297375).
• ScrubberWidget now supports all figure formats (c317db4).
• Allowed customizing legend positions on Bars Elements (5a12882).
• Support for multiple colorbars on one axis (aac7b92).
• .reindex on NdElement types now support converting between key and value dimensions allowing more powerful conversions. (03ac3ce)
• Improved support for casting between Element types (cdaab4e, b2ad91b, ce7fe2d, 865b4d5).
• The %%opts cell magic may now be used multiple times in the same cell (2a77fd0)
• Matplotlib rcParams can now be set correctly per figure (751210f).
• Improved OptionTree repr which now works with eval (2f824c1).
• Refactor of rendering system and IPython extension to allow easy swapping of plotting backend (#141)
• Large plotting optimization by computing tight bbox_inches once (e34e339).
• Widgets now cache frames in the DOM, avoiding flickering in some browsers and make use of jinja2 template inheritance. (fc7dd2b)
• Calling a HoloViews object without arguments now clears any associated custom styles. (9e8c343)

API Changes

• Renamed key_dimensions and value_dimensions to kdims and vdims respectively, while providing backward compatibility for passing and accessing the long names (8feb7d2).
• Combined x/y/zticker plot options into x/y/zticks parameters which now accept an explicit number of ticks, an explicit list of tick positions (and labels), and a matplotlib tick locator.
• Changed backend options in %output magic, nbagg and d3 are now modes of the matplotlib backend and can be selected with backend='matplotlib:nbagg' and backend='matplotlib:mpld3' respectively. The 'd3' and 'nbagg' options remain supported but will be deprecated in future.
• Customizations should no longer be applied directly to Store.options; the Store.options(backend='matplotlib') object should be customized instead. There is no longer a need to call the deprecated Store.register_plots method.

Version 1.2.0

Since the last release we closed over 20 issues and have made 334 commits, adding a ton of functionality and fixing a large range of bugs in the process.
