Hey all, We are pleased to finally announce the release of matplotlib 1.5.0! It has been over a year since the last feature release and we have had over 230 people contribute to this cycle. This release of matplotlib has several major new features including - Auto-redraw using the object-oriented API in interactive mode. - Most plotting functions now support labeled data API [Jan Schulz]. - Color cycling has extended to all style properties [Ben Root]. - Four new perceptually uniform color maps, including the soon-to-be default 'viridis'. [Stefan van der Walt and Nathaniel Smith]. - More included style sheets. - Many small plotting improvements. - Proposed new framework for managing the GUI toolbar and tools. - Pixel-value on mouse over for imshow [Steven Silvester] For demos of some of these features in action see this notebook: https://gist.github.com/tacaswell/72b0d579aeb54d4fbf87 which is version of the talk I presented at scipy, pydata Seattle and pygotham this summer. There will be more in-depth demos of the new features coming. This release has a new required dependency, cycler <http://matplotlib.org/cycler> , for composing complex style cycles. In 1.5.0 we have dropped official support for python 2.6 and 3.3. The next matplotlib release will be the 2.0 default-style-only release, planned for 1-2 months from now. Tom
