Please see our full release announcement on the Plotly Community Forum: https://community.plotly.com/t/announcing-plotly-js-2-0/53675

Our commitment to semantic versioning requires us to make this next release a major version bump because we are making some backwards-incompatible changes to older and deprecated features (see below), but we see this as a low-risk maintenance release and we expect that the vast majority of users should plan to upgrade without fearing significant issues, including Javascript developers who embed Plotly.js directly in their apps or websites, as well as data scientists using Plotly.js via Plotly.py in a notebook environment, and of course Dash app developers!

Added

  • CSP safety: refactored to avoid usage of function constructors from basic, cartesian, finance, geo, and mapbox
    partial bundles and added tests to ensure that they will not again do so in the future [#5359, #5383, #5387],
    with thanks to Equinor for sponsoring the related development!
  • Add strict partial bundle [#5413, #5444], which includes
    the maximal subset of the library which does not rely on function constructors
  • Add custom-bundle script to facilitate generation of custom bundles [#5527, #5508, #5605, #5712]
  • Add mock validation utility [#5653]
  • Implement "fast" zsmooth option for image trace [#5354, #5386],
    with thanks to @almarklein for the contribution!
  • Implement various marker.pattern options in histogram, bar and barpolar traces [#5520, #5537]
    with thanks to @s417-lama for the contribution!
  • Implement ticklabeloverflow options on cartesian axes and colorbars to drop tick labels going outside div or domain [#5584]
  • Implement (x|y|z)hoverformat, (u|v|w)hoverformat and valueformat to cartesian and gl3d traces [#5563]
  • Implement "(x|y)other" hovertemplate options to format differing positions in compare and unified modes [#5690]
  • Add layout and template attributes to facilitate enabling and disabling predefined modebar buttons e.g. shape drawing and "v1hovermode" via modebar.add and modebar.remove [#5660]

  • Drop Plotly.plot from the API [#5412, #5370, #5393]
  • Drop Plotly.Queue from the API [#5423]
  • Drop non-object role keys from attribute definition [#5425, #5432]
  • Drop deprecated contourgl and area traces as well as deprecated legacy
    pre-scatterpolar polar-related attributes bar.t, bar.r,
    scatter.t, scatter.r, layout.radialaxis, layout.angularaxis and
    gd.framework [#5399, #5408, #5409, #5398, #5438]

  • Default hovermode to "closest" [#5647]
  • Default textposition to "auto" in bar, histogram and waterfall traces [#5638]
