What's new in Cloudera Data Visualization 8.0.5

Cloudera Data Visualization 8.0.5 was released on July 18, 2025, introducing the following changes.

New features and improvements

This release includes several enhancements across dataset management, system integration, connectivity, visualization and user interface improvements.

Dataset management
VIZ-2948 – Added ability to compare dataset versions

The redesigned Version Control page now includes a comparison view that highlights differences between dataset versions. This improvement of the dataset versioning feature [Technical Preview] makes it easier to track changes and support auditing and collaboration workflows. When dataset versioning is enabled, you can now view and compare previous versions against the current one. For more information, see Tracking dataset versions.

Environment and system integration
VIZ-3288, VIZ-3389 – IPv6 support for Cloudera Data Visualization

Cloudera Data Visualization now supports IPv6 through the new USE_IPV6 environment variable. When USE_IPV6=true, Cloudera Data Visualization switches to IPv6. In Cloudera Base on premises deployments, IPv6 is enabled by default. You can disable it by setting USE_IPV6=false.

VIZ-3434 – Custom Python interpreter support

You can now configure Cloudera Data Visualization to use a custom or system-installed Python interpreter instead of the embedded one. Set the environment variable DATAVIZ_USE_EMBEDDED_PYTHON=false to enable this option. For more information, see Specifying a custom Python interpreter.

Visualization rendering and data export
VIZ-3195 – Improved number formatting in Excel downloads
Excel downloads now preserve display formatting, allowing you to sort and calculate without additional formatting.
  • Numbers are exported as actual numbers with formatting applied (for example: currency, percentages), instead of plain text.
  • String values that start with = no longer trigger Excel formula evaluation.

This update ensures exported Excel files are more accurate, usable, and compatible with downstream workflows.

VIZ-3377 – Improved support for East Asian characters in word cloud visuals

Word clouds now correctly render East Asian (such as Chinese, Japanese, and Korean) text by ensuring a valid SVG structure. This update ensures consistent display across East Asian languages.

AI Visual enhancement
VIZ-3361 – Improved error handling in AI Visual

Enhanced error messages for the AI Visual to better guide users when configuration or tokenizing issues occur.

Usability and interface enhancements
VIZ-3197 – Improved mobile homepage

The mobile Home/Visuals page now supports dashboard search and full workspace navigation. Instead of showing only All, Public, and Private, now all available workspaces are listed on the homepage for easier access. For more information about using Cloudera Data Visualization on mobile, see Mobile devices.

VIZ-3216 – Improved static asset management interface

The Manage Image, CSS, and JS Assets page has been enhanced to support easier asset management. The updated interface now includes:

  • Pagination for navigating large asset lists
  • Search functionality to quickly locate assets
  • Column sorting for easier organization
  • Bulk delete to remove multiple assets at once
VIZ-3300 – Improved formatting and validation for email addresses in the Email modal

The Reply To and From fields in the Email modal now correctly support email addresses in both name <email@domain.com> and email@domain.com formats.

  • Angle brackets (< >) are no longer escaped incorrectly in the UI.
  • If no name is provided, the Cloudera Data Visualization username is used as the display name.
VIZ-3394 – Improved error handling and configuration for Map Visual

Simplified error messages when API keys are missing, added clearer messaging when WebGL is unavailable, and made map location settings easier to manage.

VIZ-3430 – Modals no longer close on outside click or clicking "Esc"

Most Cloudera Data Visualization modals (for example: Data Connection, Email, Static Assets, and Users/Groups) now only close when you click Close or x to prevent losing user input. Informational modals remain dismissible by outside click or using "Esc."

Fixed issues

VIZ-2839 + VIZ-3346 – Visual improvements to the Notifications modal
  • Fixed an issue where long, unbroken notification text caused horizontal scrolling to behave incorrectly, jumping back to the beginning and preventing access to the full content. The scroll behavior is now stable, allowing users to view the entire notification without interruption.
  • Previously, hovering over a notification caused the pinned icon to appear and shrink the text area, resulting in visual jitter. This has been fixed by setting a minimum width for the icon container, keeping text alignment and width consistent whether the icon is visible or not.
VIZ-3161 – Dashboard filters now reset correctly regardless of initial filters

Fixed an issue where the Reset Filters button did not work properly if the dashboard had no initial filters. The reset logic now correctly determines the default filter state based on the dashboard’s configuration.

VIZ-3391 – Fixed PDF download options on dashboards
  • Fixed missing PDF download options, Current sheet, One sheet per page, and One visual per page on current sheet, from the Download as > PDF dropdown on dashboards.
  • Resolved errors occurring when selecting One sheet per page or One visual per page on current sheet in the app and email modal.
  • Implemented the One visual per page PDF download option, ensuring each visual is correctly isolated, positioned, and saved to its own PDF page.
VIZ-3392 – Import from version 8.0.2 no longer fails due to missing annotation field

The Reports model had an annotation field in 8.0.2 which was removed in a later migration. Now, during import, the missing annotation field is safely ignored to prevent failure when importing reports from 8.0.2.

VIZ-3310 , VIZ-3367, VIZ-3397, VIZ-3398, VIZ-3422, VIZ-3423, VIZ-3432, VIZ-3443, VIZ-3445, VIZ-3452

Fixed critical and high-severity package vulnerability issues identified in Cloudera Data Visualization 8.0.4.

VIZ-3416 – Dashboard panel properly hides visuals when switching datasets

When switching datasets in the dashboard or application builder, the visual list shows and hides correctly.

VIZ-3425 – Visibility of NEW SQL button is tied to permissions

The NEW SQL button available on the Home page now only appears if direct access is enabled and the user has the Create datasets, explore tables permission on at least one data connection. It is hidden for users without these permissions.

VIZ-3438 – Delete Usage Data modal now appears correctly in Site Settings

Fixed an issue where the Delete Usage Data modal was not appearing in the Site Settings interface. Users can now properly access and use this feature to manage usage data.
