  "summary": "Added Add minscale , maxscale geo plot attributes [ #7371 ], with thanks to @mojoaxel for the contribution! Enable TypeScript compatibility within the library and start exporting types [ #7680 ] Add quiver trace type to visualize vector fields using arrows [ #7710 , #7945 ], with thanks to @degzhaus for the contribution! Use dashed markers in legend for shape traces with dash configured [ #7845 ] Add direction attribute to the Sankey trace, controlling the flow direction along the orientation axis [ #7870 ], with thanks to @wf-r for the contribution! forward keeps sources on the left (horizontal) or top (vertical) reversed moves them to the right or bottom Add sort option to Sankey links and nodes [ #7873 ], with thanks to @adamreeve for the contribution! Add support for MathJax v4 [ #7898 ] Add top-level xPixel and yPixel keys to hover and click event data, corresponding to the pixel position of the cursor relative to the top-left corner of the graph div [ #7966 ] When hoveranywhere is enabled, emit a plotly_unhover event when the cursor leaves the plot area [ #7966 ] Removed Breaking : Remove scattermapbox , choroplethmapbox , densitymapbox trace types, the mapbox subplot, and the mapboxAccessToken config option [ #7860 ] These traces have been deprecated since v3. Use the equivalent *map traces going forward. Breaking : Drop support for MathJax v2 [ #7898 ] MathJax v3 and v4 are now supported in plotly.js Remove config attributes showLink , linkText , sendData , showSources , and showEditInChartStudio , as well as trace attribute stream , since all of these were associated with Chart Studio and are no longer needed [ #7812 ] Remove all *src attributes, as well as layout.hidesources attribute, from the schema [ #7829 ] Remove internal trace._fullInput property and other dead code related to the removed transforms feature. No user-facing changes expected [ #7834 ] Changed Breaking : Switch color processing library from TinyColor to culori [ #7536 ], #7962 ] rgb() / rgba() strings with decimal 0–1 fractions are no longer interpreted as percentage values (relative to 255) hsv() color strings are no longer permitted New color formats are now supported: #ff0000aa , #f00a , rgb(255 0 0) , rgba(255 0 0 / 0.5) , hsl(0 100% 50% / 0.5) , hsla(0, 100%, 50%, 0.5) , lab() , lch() , oklab() , oklch() , color() , hsl(0.5turn 60% 40%) , hsl(none 60% 40%) rgb() now accepts an optional alpha, so rgb(255, 0, 0, 0.5) is no longer opaque ( rgb and rgba are aliases per spec ) Color strings that are not valid CSS are now rejected, such as hsl(120, 50% 50%) Contrasting text and border colors are picked by WCAG contrast ratio, so labels on saturated mid-tone fills may switch from dark to white Breaking : Set default layout.axis.tickmode to 'sync' when axis is overlaying [ #7684 ] Breaking : Change splom.axis.matches default from false to true [ #7843 ] Breaking : Replace country-regex with country-iso-search to search for country names in choropleth, scattergeo traces [ #7856 ] The vast majority of country names are handled exactly the same with the new library; a small number of legacy entries have been removed Breaking : Update minimum required Node version to 22 [ #7861 ] Breaking: Change layout.geo.fitbounds default from false to 'locations' [ #7895 ] geo subplots will now auto-fit the initial view to the trace data Set fitbounds: false explicitly to opt out Breaking : Return actual data values (rather than calcdata values) for xvals / yvals in hoveranywhere and clickanywhere events. Date and category axes will now return strings rather than numeric values. Linear and log axis values remain unchanged. [ #7964 ] Enable scattermap icons to render in color, upgrade Maki icons version to 8.2, and standardize scattermap legend icons to circles [ #7825 ] Use plot title as default filename for \"Download plot\" button [ #7828 ] Change signature of plots.graphJson() function to remove mode argument [ #7829 ] Upgrade plotly/d3-sankey to 0.12.3. [ #7830 ], with thanks to @adamreeve for the contribution! Update plot_config to show the \"Upload to Cloud\" button by default, and set the default server URL to cloud.plotly.com via [ #7909 ] Update \"Share chart\" dialog with more informative wording [ #7928 ] Fixed Fix histogram autobin size for single-point traces in overlay mode on data updates via Plotly.react [ #7507 ], with thanks to @Lexachoc for the contribution! Format tick labels correctly for small numbers in exponential notation [ #7768 ], with thanks to @Hasnaathussain for the contribution! Defer automargin during scroll-wheel zoom, to prevent erratic jittering while zooming [ #7815 ], with thanks to @keilogic for the contribution! Fix crash when ordering categories by value (e.g. sum descending ) with null coordinates [ #7855 ] Prevent outside bar text for zero-length bars from overlapping axis tick labels [ #7872 ], with thanks to @vizansh for the contribution! Fix scattermap , densitymap traces not showing all points by dynamically computing center , zoom values [ #7884 , #7913 ], with thanks to @palmerusaf and @DhruvGarg111 for the contributions! Fix GeoJSON bounding-box computation for choropleth and scattergeo traces whose geometry crosses the antimeridian [ #7891 ] Fix hovertemplate / texttemplate / tickformat / hoverformat improperly handling d3-format specs that start with a sign flag such as +.2f [ #7900 ], with thanks to @TemRevil for the contribution! Snap cartesian axis tick values to multiple of delta so custom tickformat (e.g. \"~r\" ) no longer shows floating-point artifacts [ #7901 ], with thanks to @arieleli01212 and @kirthi-b for the contribution! Fix scattermap box and lasso selection across the antimeridian [ #7905 ], with thanks to @coyaSONG for the contribution! Fix crash (\"Something went wrong with axis scaling\") when a colorbar's title or padding leaves it with a negative domain length [ #7908 ], with thanks to @zeehio for the contribution! Prevent MultiPolygon features with no positive-area polygon from aborting choropleth rendering [ #7921 ], with thanks to @swjturay for the contribution! Fix geo.fitbounds: 'locations' when mixing antimeridian-crossing territories with normal ones [ #7948 ] Fix issue where plot fails to render if unsupported MathJax version is present on page [ #7951 ] Fix numeric color sorting for bundled parallel-categories (parcats) paths [ #7959 ], with thanks to @CAOShurong for the contribution!",
