For more information, see the [DataLens](https://t.me/YandexDataLens/28631/148518) Telegram chat. * When you [copy](../operations/dashboard/add-selector.md#copy-paste) a selector from one tab and paste it into another tab of the current dashboard, you can now link it to the original selector or create a new independent selector. * Added the ability to customize [line width](../concepts/chart/settings.md#forms-settings) as well as line cap and junction style on [line charts](../visualization-ref/line-chart.md#wizard-sections). This new line setup option allows you to: * Focus on the main point. * Build a visual hierarchy. * Make the multi-line chart easier to read. * Improve adaptability for the mobile version and other non-standard cases. * For [background data export from a chart](../concepts/chart/data-export.md#background-export), we added support for export in `XLSX` format: * You can use background export for [tables](../visualization-ref/table-chart.md) in the [wizard](../concepts/chart/dataset-based-charts.md). * [Pagination](../concepts/chart/settings.md#common-settings) must be on in the table settings, and more than one page must be displayed. * The maximum number of rows in the table is 1,000,000. * The maximum file size is 1 GB. Learn more about background export [limitations](../concepts/chart/data-export.md#restrictions). * When [exporting and importing workbooks](../workbooks-collections/export-and-import.md), [Yandex Query](../operations/connection/create-yandex-query.md) and [Yandex Monitoring](../operations/connection/create-monitoring.md) connections are now available. ### Improvements in reports {#report-changes} * We added support for links in reports. In the [Text](../reports/report-operations.md#add-widget) widget, you can create a link: * `#title` type: To a title in the current report. * `#page-1` type: To a specific page in the current report. * Absolute link: To go to a page on the internet. {% cut "Link to page" %} ![report-text-link](../../_assets/datalens/release-notes/report-text-link.png =532x264) {% endcut %} You can use created links in reports in [preview](../reports/report-operations.md#report-preview) mode or in [exported](../reports/report-operations.md#report-export) PDF files. * Added support for new formats in reports: `16:9 (Full HD)`, `16:9 (2K)`, and `16:9 (4K)`. {% cut "Displaying the report in specific formats" %} ![report-16-9](../../_assets/datalens/release-notes/report-16-9.png) {% endcut %} ## Fixes and improvements {#fixes} * For [Gravity UI Charts](../charts/editor/widgets/gravity-ui.md) and [Advanced charts](../charts/editor/widgets/advanced.md), added the ability to follow a link by clicking an element in the chart using `window.open` in the [Editor.wrapFn](../charts/editor/methods.md#wrap) method. * In the Advanced chart, fixed the error of using args in the `Editor.wrapFn` method. * Fixed the error where options used to create [aliases](../dashboard/link.md#alias) were not displayed in the link dialog for [JS selectors](../charts/editor/add-js-selector.md) built based on datasets. * In [background export](../concepts/chart/data-export.md#background-export) from a chart, fixed the issue where field renaming at the chart level was disregarded and the names were taken from the dataset. * The dataset-based selector now highlights the field if it was removed from the dataset. * Made [mermaid diagrams](../dashboard/markdown.md#mermaid) more secure: now most HTML elements get filtered out, and the diagram is displayed without them. * Sped up the `Editor.wrapFn` function and optimized the libraries provided in its arguments. * Fixed the date in the sidebar [trial period](../pricing.md#trial) countdown indicator. Previously, the indication was one day up. * Fixed the alignment of icons in the workbook object list. * In DataLens Gallery, renamed the `Product management` category to `Product`. ### Fixes in connections {#connection-fixes} * Connection settings now automatically expand the fields that have failed validation when attempting to create or save a connection. * Removed the **Edit** button from connections that are not editable. * Fixed some errors when connecting to a [file](../operations/connection/create-file.md). ### Fixes in datasets {#dashboard-fixes} * When going to the [dataset creation](../dataset/create-dataset.md) page from the side navigation, an _unsaved changes_ warning will now be displayed if the user is already on this page and the form contains unsaved changes. * Now you cannot create or save a dataset if there are no tables in the workspace. * In the [dataset field](../dataset/create-dataset.md#setup-fields) color settings window, long elements in the left column are now correctly truncated with ellipses. * Fixed the selection of tables in the list after deleting them from the workspace. * The undo (**Ctrl** (**Cmd**) + **Z**) and redo (**Ctrl** (**Cmd**) + **Shift** + **Z**) hotkeys are now blocked if the settings window is open in the dataset. ### Fixes in charts {#chart-fixes} * Fixed incorrect display of: * Chart icons, which you could see from time to time in the [link settings](../operations/dashboard/dashboard-links.md) window. * Modeling icons when adding trend and smoothing lines to a chart in Safari. * Load indicator when entering values ​​in the chart's [filter](../concepts/chart/settings.md#filter) settings. * Fixed a chart execution error due to special data values ​​in the **Colors** section. * Fixed [saving chart as an image](../operations/chart/save-as-image.md) on mobile devices with screen resolution of 1600 x 720 pixels. ### Dashboard changes {#dashboard-fixes} * Implemented a switch back from a newly added tab to the first existing one after you cancel the edit. * Full text of the chart title is now displayed on hover.
