This release includes a complete and long awaited overhaul of the HoloViews documentation and website, with a new gallery, getting-started section, and logo. In the process, we have also improved and made small fixes to all of the major new functionality that appeared in 1.7.0 but was not properly documented until now. We want to thank all our old and new contributors for providing feedback, bug reports, and pull requests.
