on GitHub

This release includes major contributions from @jonmmease (quadmesh and filled-area support), @brendancol (geospatial toolbox, tile previewer), @philippjfr (distributed regridding, dask performance), and @jsignell (examples, maintenance, website).

New features:

• Native quadmesh (canvas.quadmesh()) support (for rectilinear and curvilinear grids -- 3X faster than approximating with a trimesh; #779)
• Filled area (canvas.area()) support (#734)
• Expanded geospatial toolbox, with support for:
  • Zonal statistics (#782)
  • Calculating viewshed (#781)
  • Calculating proximity (Euclidean and other distance metrics, #772)
• Distributed raster regridding with Dask (#762)
• Improved dask performance (#798, #801)
• tile_previewer utility function (simple Bokeh-based plotting of local tile sources for debugging; #761)

Bugfixes and compatibility:

• Compatibility with latest Numba, Intake, Pandas, and Xarray (#763, #768, #791)
• Improved datetime support (#803)
• Simplified docs (now built on Travis, and no longer requiring GeoViews) and examples (now on examples.pyviz.org)
• Skip rendering of empty tiles (#760)
• Improved performance for point, area, and line glyphs (#780)
• InteractiveImage and Pipeline are now deprecated; removed from examples (#751)
