Changes in basic featuresChanges in basic features

• Billing account lists now include billing accounts associated with other organizations if the user has been granted permissions for those organizations.

• Released the first version of the public API.

  DataLens provides a public API (https://api.datalens.tech) to automate operations with dashboards, charts, datasets, and connections.

  DataLens Public API is a collection of methods similar to that used in the DataLens web interface. This API is described by the OpenAPI specification and authenticated via the Yandex Cloud IAM tokens.

  To use the API, you need an IAM token and an organization ID.

Fixes and improvementsFixes and improvements

• In DataLens Gallery, the Contact the author form now opens in a dialog instead of a new tab.

• Added support for reassigning a seat about to expire.

• Fixed errors with redefining the menu item background color when customizing the UI in some themes.

• In the link settings window for datasets, added a tooltip and field name search. Previously, with many long and similar field names, finding and selecting the one you need was inconvenient.

• In the formula editor for creating calculated fields in datasets and charts, the description window now displays a helpful tip, links to user guides, and dashboard with examples when no function is selected in the list on the left.

• Fixed an issue where text from the UI was unintentionally copied to the clipboard on certain pages.

Dashboard fixesDashboard fixes

• Now you can control which dashboard tabs display a selector. When switching between these tabs, the selector's value is preserved.

  Use the Show in tabs setting to configure the selector display on the dashboard:

  • Current tab <tab_name>: Display the selector on the specified tab. This is the default option for a single selector.
  • Selected tabs: Select one or multiple tabs where you need to display the selector. By default, the current tab is selected.
  • All tabs: The selector will be displayed on all tabs. This option is available for a single selector.
  • From group settings <group_value>: Selector display will be based on the advanced settings of the selector group widget. This option is available only for a selector within a group.

  For widgets with multiple selectors, you can configure visibility in the Group settings tab.

  For more information, see Adding a selector to a dashboard in Yandex DataLens.

• Implemented selector value persistence when switching tabs. Now, if you set a selector value, switch to another tab, and return, the selector retains the value.

• Dashboards now support configuring links for charts from unopened widget tabs:

  • Select the chart at the top of the link settings window: the chart's data will load, allowing you to configure the link.
  • In the link settings window, choose a selector, then, in the Link type column, click the relevant chart row in the widget list: the chart's data will load, allowing you to configure the link.

• Fixed stable table rendering on initial dashboard loading.

• Fixed an issue where the color of Mermaid diagrams in dashboard text widgets in the visual editor was different from their actual color on the dashboard.

• Fixed an error where, when setting up aliases with certain QL charts, parameters configured in the QL chart UI did not appear in the parameter selection list.

• In dashboard edit mode, added highlighting to the button for selectors with group visibility set to All tabs or Selected tabs.

Fixes in chartsFixes in charts

• In line charts, fixed an issue with line style configuration for multiple measures; previously, the line style was rendered correctly only for one measure.
• In maps, fixed drag-and-drop functionality for adding fields to Layer filters.
• Fixed auto-application of metric settings in QL charts.
