Hi everyone,

We’ve just released Oxygen XML Editor 28.1 and I wanted to share a quick overview of some of the key additions.

This release comes with important enhancements in AI-powered workflows, built-in support for S1000D® issue 4.x, improved DITA editing and PDF publishing, as well as introducing the new Oxygen AI Translator add-on.

Here are a few highlights:

    * Planner chat mode
    A new Planner chat mode is available with the latest release of the Oxygen AI Positron add-on that allows the AI to explore your project, propose multi-step plans, and coordinate work across specialized agents. You can review each step (including tool calls and results) before execution, making it easier to handle larger tasks like bulk transformations or content migrations.

    * Sensitive data masking
    Personal and confidential information (such as emails, phone numbers, API keys) is automatically detected and masked before being sent to AI services (you can extend this with custom patterns) and the original data is restored in responses so your content remains accurate.

    * Enhanced AI interaction and control
    Files created or modified by AI are now shown directly in the chat, where you can review and accept or discard changes, down to specific fragments. There is also support for custom chat modes that can delegate tasks to specialized AI agents, tool selection to fine-tune AI capabilities, command-line integration (with your approval), and Vision support for including images in AI analysis when relevant.

    * Built-in S1000D support (issue 4.x)
    Built-in support for S1000D content includes schema-aware editing, validation, content completion, multiple authoring modes, BREX editing and conversion, Smart Paste from web browsers or Word documents, and ready-to-use templates for data and publication modules.

    * Oxygen AI Translator add-on
    A new add-on is available for XLIFF workflows that provides AI-powered translation with quality checks, structural validation, translation memory (TMX), custom instructions, caching for performance and cost control, and progress tracking with job persistence across system restarts.

    * DITA and publishing improvements
    You can now edit change history more easily in DITA prologs using form controls, and PDF output benefits from better font fallback at character level, improving multilingual rendering.

    * Developer tooling
    XProc 3.0/3.1 support is enhanced with improved Saxon XInclude handling, better options parsing, and integrated HTML5 validation.

    * Comparison and collaboration updates
    File comparison includes configurable comment callout widths and the option to include timestamps and user information in reports.

    * Updated add-ons and components
    The Git Client add-on now supports multiple worktrees and introduces an AI-assisted “Explain commit” action. The release also includes numerous library and platform updates.
