Changes in basic features

New works available in DataLens Gallery. For more information, see the DataLens Telegram chat.
When you copy 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 as well as line cap and junction style on line charts.

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, we added support for export in XLSX format:
- You can use background export for tables in the wizard.
- Pagination 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.

When exporting and importing workbooks, Yandex Query and Yandex Monitoring connections are now available.

We added support for links in reports. In the Text 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.
Link to page

You can use created links in reports in preview mode or in exported PDF files.
Added support for new formats in reports: 16:9 (Full HD), 16:9 (2K), and 16:9 (4K).

Displaying the report in specific formats

For Gravity UI Charts and Advanced charts, added the ability to follow a link by clicking an element in the chart using window.open in the Editor.wrapFn 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 were not displayed in the link dialog for JS selectors built based on datasets.
In 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 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 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.

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.

When going to the dataset creation 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 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.

Fixed incorrect display of:
- Chart icons, which you could see from time to time in the link settings window.
- Modeling icons when adding trend and smoothing lines to a chart in Safari.
- Load indicator when entering values in the chart's filter settings.
Fixed a chart execution error due to special data values in the Colors section.
Fixed saving chart as an image on mobile devices with screen resolution of 1600 x 720 pixels.

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.
