Oxygen XML Web Author version 26.1.0 is an incremental release for the innovative web-based XML authoring tool. This release has some interesting new features for DITA users, introducing support for DITA-OT project files and providing better handling of DITAVAL filters. The DITA Map pane allows users to specify a DITA-OT project file and choose between the contexts defined within it. Users may also easily switch profiling conditions, and there is the option to hide or present as grayed out content that is excluded by the current filter in the document, DITA Maps pane, and in the Outline pane.

The AI Positron Assistant's feature for previewing changes was improved to allow choosing which of the AI's proposed changes will be incorporated into users' documents. When dragging a node within the Outline pane, the outline tree automatically scrolls along with the movement to make it easier to precisely drop the node where needed. The Unicode support was improved to better support surrogate characters (e.g. emoji characters) and the text mode is available as read-only mode for concurrent editing sessions. When Markdown content is pasted within DITA, DocBook, TEI, or XHTML documents, it is automatically converted to the target vocabulary by the smart paste functionality.

If users develop Web Author customizations, the new CSS Inspector lets them see the styles of the selected element and the process of uploading a framework now includes validation to keep customized frameworks error-free. Server logs are available from the Administration Page to help troubleshoot issues with the Web Author server and some new URL parameters are also available to impose a DITAVAL filter or a DITA-OT project context for filtering the document.

Version 26.1 also brings a variety of performance improvements, security enhancements, API and component updates, and bug fixes.
