Changes in basic featuresChanges in basic features

• Added dataset versioning. You can now view a list of previously saved dataset changes and roll back to a previous version.

• In the chart axis settings, added the ability to select Manually for label formatting.

• When using a connection to PostgreSQL, added the ability to provide TODAY() as the first argument for the DATEADD function.

• Updated the settings form for calculated fields in datasets and charts: the field name is now displayed in a separate row.

• Added highlighting of features available with the Business service plan in some menus.

  Object creation menu in workbooks

  

• Added a privacy policy: click Help center → Privacy policy in the left-hand navigation panel.

• Implemented adding chart info in the wizard, Editor, and in QL charts.

• Added the Retry button in the window with related objects; it appears when an error occurs on window opening.

• Now only a user with the datalens.instances.admin or datalens.admin role can create a DataLens Usage Analytics connection. To allow other users to view a connection and run queries to it, the connection administrator can configure object access permissions.

• Added a connection to Trino. A connector enables you to connect either to a managed database in the current Yandex Cloud organization or to an external database with your own credentials and an option to select the authentication type.

• Modified the behavior of signed parameters in private embeddings.

  • Now signed parameters take priority. If a widget gets both a signed and an external parameter of the same name at the same time, the signed one will apply.
  • Signed parameter selectors do not affect the dashboard charts.

Yandex DataLens updatesYandex DataLens updates

Released a major Yandex DataLens update:

• Changed the domain to datalens.ru. It is now the single point of access where you can download the on-premise distribution, explore the product, or view a ready-to-use dashboard.

  Please note:

  • The promo page and DataLens itself are now available at datalens.ru.
  • The new secure embedding URL is datalens.ru/embeds/*. On October 9, we will enable redirection from the legacy secure embedding URLs to the new addresses. Make sure to make datalens.ru an allowed domain in the security settings of the website or application with embedded objects.
  • Public charts and dashboards are still available at datalens.yandex.

• Updated the design and contents of the DataLens promo page.

  

Fixes and improvementsFixes and improvements

• Restored the ability to open a chart as a table. To open your chart as a table, click → Open as a table in the top-right corner of the chart.
• Fixed the incorrect closing of the settings window when editing a dashboard access error.
• Fixed the error where data export got implicitly disabled when editing a dataset.
• Fixed the error caused by attempts to save a selector in which a field could not be validated.
• Fixed incorrect name saving when creating a calculated field in a chart.
• Fixed the issue where disabling export at the connection or dataset level did not stop export from QL charts based on that connection or dataset. Now export from all charts will be blocked.
