New features
The following has been added in this release of Studio for InDesign and InCopy:
- When placing an article onto frames on a layout, the Element Labels of the layout frames can now be maintained instead of having them replaced by the article. When an article is placed on existing frames on a layout, the default behavior of Studio for InDesign is that any Element Labels that are assigned to the frames on the layout are replaced by the Element Labels of the frames of the article.
In certain workflows though, it is preferred that the Element Labels of the frames on the layout are maintained.
This behavior can now be controlled through the following new preference:
Element Labels > Override frame Element Label with placed article component Element Label
By default, the preference is enabled, thereby matching the current behavior and ensuring full backward compatibility with existing workflows.
If the Element Labels of the layout frame should be maintained, the preference can be disabled.
The behavior can also be controlled through a new scripting API property named overrideFrameElementLabelOnPlace. This property exposes the same preference through the Studio Preferences scripting object, allowing scripts to retrieve and modify the setting programmatically.
The scripting implementation uses the same underlying preference storage as the user interface, ensuring there is a single source of truth for the setting. Changes made through either the UI or scripting remain synchronized.

Known issues
The following known issues exist in this release of Studio for InDesign and InCopy:
- Studio for InDesign for Adobe 2026 is only supported in combination with InDesign 21.3 and later. This is because InDesign 21.2 introduced a persistent dependency on the Layout UI plug-in: a native InDesign plug-in that is not available in InDesign Server. As a result, InDesign Server can behave unstable when processing documents that have been saved with InDesign 21.2. See also our announcement about this issue. This issue has been resolved by Adobe in version 21.3; we strongly advise to avoid InDesign 2026 version 21.2 when using InDesign Server.
- Articles with images inside a Flex layout are not supported. This is because of an Adobe issue whereby images inside a Flex layout are skipped when creating or checking in articles. Once this issue has been resolved by Adobe, it will be possible to add images inside a Flex layout to an article.

New features
No features have been added in this release of Studio for InDesign and InCopy.
Changes
The following changes have been made in this release of Studio for InDesign and InCopy:
- Additional methods have been added for changing properties for multiple objects. Changing properties for multiple selected objects of the same type and belonging to the same Brand is now also possible for objects placed on a layout, and from within the Elements panel. In previous versions, this was only possible from within the Studio panel.
- The menu command 'Properties...' has been renamed to 'Component Properties...' to better distinguish it from another command with the name 'Properties...'. The menu command for changing properties for multiple objects has been renamed from 'Properties...' to 'Component Properties...'. When assigning a keyboard shortcut to this command, it makes it easier to distinguish it from the 'Properties...' command used for changing properties when a single object has been selected.
- A new scripting API has been added to expose the version details of the installed plug-ins for Studio for InDesign and InCopy. To determine which version of Studio for InDesign and InCopy is installed and to thereby reliably tailor behavior to the detected versions, the following API surface has been added:
- app.studioPlugins
- Type: StudioPlugins
- Access: read-only
- Purpose: root object for scripting relating to the Studio for InDesign and InCopy plug-ins
- app.studioPlugins.version
- Type: PluginVersion
- Access: read-only
- Purpose: provides the full version details of the Studio for InDesign and InCopy plug-ins
- PluginVersion exposes the following read-only properties:
- major (Number) – major version
- minor (Number) – minor version
- patch (Number) – patch version
- build (Number) – build number
- release (String) – release type, such as 'daily', 'release'
For more information and examples, see the Scripting Guide:

Release date: 23 March 2026
Downloads
The download files for this version of Studio for InDesign and InCopy can be found in the Release announcement.
New features
The following features have been added in this release of Studio for InDesign and InCopy:
- Support for Adobe 2026. Studio for InDesign, InCopy, and InDesign Server version 21 can be used with the following Adobe applications:
- InDesign 2026 version 21.3.0 or higher (see Known issues)
- InCopy 2026 version 21.3.0 or higher
- InDesign Server 2026 version 21.1.0 or higher
- Support for opening Adobe PDF and Illustrator files as a new layout has been added to Studio for InDesign. Adobe InDesign 2026 adds support for opening/converting PDF and Illustrator files as InDesign documents. Support for this has been added to the Studio panel in Studio for InDesign.
To open a PDF or Illustrator file and convert it to a layout from the Studio panel in InDesign, right-click the file and choose Open from the context menu.
Opening a PDF or Illustrator file as an InDesign document from scripting is possible by using the app.openObject() scripting call.
Limitations
- Opening an Advert PDF or Illustrator file as an InDesign document is currently not supported.
- Opening a PDF or Illustrator file in JavaScript in InDesign Server is not possible. This functionality is not supported by Adobe.
- Adobe reports limitations on this functionality, depending on the complexity and source of the PDF. See Convert PDFs to InDesign Documents. The same limitations and shortcomings apply to opening PDF files in Studio for InDesign.

Changes
The following changes have been made in this release of Studio for InDesign and InCopy:
- Filtering on file type in the Studio panel and the Dossier panel has been made more user friendly. When using the Studio panel or the Dossier panel, more files are often shown than need to be worked on. To reduce the number of files shown, the results can be filtered by selecting or deselecting file types from a menu. In previous versions, this menu could be accessed by right-clicking the Search pane of the panel, or via the panel menu.
To make the presence of this filter more visible and make accessing it easier, a Filter icon has now been added to the Search pane in the Studio panel and in the Dossier panel. This replaces the method of right-clicking the Search pane; this method has been removed. The menu can still also be accessed via the panel menu.
To make it clear when a filter is applied, a blue check mark is shown in the Filter icon.
- Changes have been made to the configuration for informing users about upcoming deadlines. When deadlines are used, it is beneficial to configure the system in such a way so that users are informed at a specified time that a deadline is about to expire. In previous versions, this was done by sending messages using RabbitMQ.
This method has the following downsides:
- It can negatively affect performance
- Even when deadlines are not used, messages can still be triggered
Because of this, as well as the fact that the deadline functionality is not used by many customers, Studio for InDesign and InCopy 19.0.7 no longer handles RabbitMQ messages about deadlines.
If the functionality should still be needed, it can be enabled by setting the following options:
1. Add the following as a new Feature in the config_overrule.php file:
new Feature(EnableDeadlinesUpdates),
2. Add the following to the WWSetting.xml file:
<SCEnt:EnableDeadlinesUpdates/>
