{productname} 8.3.0 was released for {enterpriseversion} and {cloudname} on Wednesday, December 10th, 2025. These release notes provide an overview of the changes for {productname} 8.3.0, including:
The following premium plugin updates were released alongside {productname} 8.3.0.
The {productname} 8.3.0 release includes an accompanying release of the Media Optimizer premium plugin.
Media Optimizer includes the following improvement and fix.
Newly uploaded videos are now responsive by default. Videos automatically scale down on smaller screens while maintaining their maximum size. For more information, see: uploadcare_video_properties configuration option.
For information on the Media Optimizer plugin, see: Media Optimizer: Video.
Previously, Media Optimizer CSS resource files were not loaded correctly. This mainly caused issues when trying to bundle this plugin. In {productname} 8.3.0, this issue has been resolved by ensuring that CSS resource files for Media Optimizer are now loaded correctly.
For information on the Media Optimizer plugin, see: Media Optimizer.
Premium plugins in {productname} 8.3.0 can now be consumed as native ES modules (import) in addition to CommonJS (require). This enhancement aligns premium plugins with the existing ESM capabilities already available in core plugins and applies to all distributed artifacts, including NPM packages and ZIP bundles. The update enables modern bundlers to automatically resolve the optimal module format, improving compatibility with ESM-focused toolchains and removing the need for CommonJS shims during integration.
{productname} 8.3.0 also includes the following improvements:
Previously, when a premium plugin was not permitted for a given license key, the plugin would be disabled without any corresponding editor message. As of 8.3.0, this behaviour has been improved: the editor now displays a notification when a plugin is disabled due to license restrictions, reducing ambiguity.
For more informaton on license keys, see: License Key.
In previous versions of {productname}, accordion behavior in readonly mode relied on the browser’s default handling, which could still modify the DOM and lead to undesirable, uncontrolled changes to the editor state. This meant that even when the editor was configured as readonly, expanding or collapsing accordion sections could alter the underlying content structure in inconsistent ways.
In {productname} 8.3.0, the Accordion plugin now explicitly manages open and close interactions in readonly mode, ensuring that any required DOM updates for toggling panels are performed in a controlled, minimally invasive manner. This improvement provides more predictable behavior, better control over how the DOM is manipulated, and a consistent user experience when interacting with accordions in readonly editors.
{productname} 8.3.0 also includes the following bug fixes:
Tooltip is now translated correctly for the dropdown chevron of the bullet and number list toolbar buttons.
Previously, an issue was identified where the tooltips for the dropdown chevrons for the Bullet list and Numbered list toolbar buttons were not translated correctly. This has been resolved in 8.3.0. The dropdown chevron of these splitbuttons now displays correctly translated tooltips on hover.
An issue was identified where removing or modifying lineheight properties on multiple elements resulted in inconsistent updates when the elements had differing values. In these cases, only the lineheight of the first line was changed or removed, while subsequent lines were not updated.
{productname} 8.3.0 resolves this issue by introducing improved toggling behavior for the permissive lineheight option, ensuring that all lines are now correctly updated or removed as expected.
Previously, an issue was identified where the font-size style applied to list items was not retained when creating new items in either numbered or bulleted lists. As a result, list items added by pressing Enter did not inherit the correct font size from the preceding item.
{productname} 8.3.0 addresses this issue by changing the behavior such that the font-size style is now consistently transferred to newly created list items. This ensures that all new list items have the correct font size.
