plotly 4.12.1

CRAN release: 2026-07-22

Completed the plot_ly() documentation for what happens when type is not specified (#2362).
Removed the dependency on the {lazyeval} package.

Closed #2483: save_image() no longer embeds Windows file paths directly into Python source passed to reticulate, fixing static image export with Kaleido on Windows.
#2495: ggplotly() now keeps merged legend titles in sync with their legend entries, fixing a case where an upstream change in rlang’s hashing could silently reorder combined legend titles (e.g. factor(vs)<br />factor(cyl)) out of step with the entries they label.

CRAN release: 2026-01-24

Upgrades plotly.js from v2.11.1 to v2.25.2 (35 releases). Key new features now available:

Multiple legends: Support for legend2, legend3, etc. with separate positioning and visibility control
Shape labels: New label attribute for shapes and label.texttemplate for parametric shapes
Marker direction: New marker.angle, marker.angleref, and marker.standoff properties for directional markers
Y-axis positioning: shift and autoshift properties to avoid y-axis overlapping in multi-axis plots
Mapbox clustering: Clustering options and bounds support for scattermapbox traces
Equal Earth projection: New map projection option for geo subplots
Pattern fills: Pattern support extended to pie, funnelarea, sunburst, icicle, and treemap charts
Editable selections: Persistent and editable selections over cartesian subplots with editSelection config option
Axis label aliases: labelalias for simplified axis label customization
Grid styling: griddash property and minor tick/grid line styling options

Also includes a security fix for prototype pollution and ~90KB bundle size reduction.
