Hello everyone,

We are proud to announce the immediate availability of the Oxygen AI Positron 8.1 plugins for all major Oxygen XML suite products, including Oxygen XML Editor, Author, Developer (desktop and Eclipse distributions), Oxygen JSON Editor, Oxygen XML Web Author, and Oxygen Content Fusion.

This update transforms XML authoring from a manual task into an orchestrated, agentic experience, integrating OpenAI’s most advanced models and a sophisticated new "Planner" mode designed to handle complex, project-wide transformations.

As AI moves from simple chat prompts to autonomous execution, Oxygen AI Positron 8.1 ensures that technical communicators and developers stay ahead of the curve with improved security, lower costs, and unprecedented flexibility.

****************************************
New in Oxygen AI Positron 8.1
****************************************

* Next-Generation Intelligence with GPT-5.2

The 8.1 release marks the integration of OpenAI’s GPT-5.2 and GPT-5.2 Thinking models, delivering state-of-the-art AI capabilities for complex, multi-step agentic tasks. To maintain a modern ecosystem, support for legacy models like GPT-4 has been retired in favor of these more intelligent alternatives.

* The "Planner": Your New AI Project Manager

The standout feature of version 8.1 is the Planner Chat Mode. Designed for resource-intensive, project-wide operations, such as converting all cross-references across a DITA map or translating an entire folder, the Planner does more than just answer questions. It explores the project, proposes a comprehensive multi-step plan, and, upon user approval, delegates tasks to specialized AI agents. This "agentic" approach bypasses traditional LLM context limits, allowing for massive changes without losing oversight.

* Sensitive Data Masking

Recognizing the importance of data privacy, Oxygen AI Positron 8.1 introduces built-in Sensitive Data Masking.
  - Automatic Protection: The system identifies and masks Personal Identifiable Information (email addresses, API keys, phone numbers) before requests reach the LLM. Customizable masking patterns are available for additional data types.
  - Seamless Restoration: Masked data is automatically restored in the AI's response, ensuring the final XML content remains accurate and secure.

* Important Enhancements

  - Optimized Efficiency: Prompt engineering improvements have significantly reduced token consumption, lowering the cost per operation for high-volume users.
  - Customizable AI Tools: New tools selector to enable or disable specific AI tools for each chat mode, support for creating custom chat modes, and actions with vision support for image analysis, allow tailoring the AI behavior to specific requirements.
  - Advanced Document Handling: Attached PDF and Word documents now preserve their internal structure (headings, tables, and styles), making document conversion and analysis more precise than ever.
  - Integrated Review Experience: Review and manage AI-modified files directly in the chat, enabling surgical precision when accepting changes.
  - Expanded Toolset: New tools, such as the ones for command-line operations, resource management (copy/move/rename), and directory listing give the AI more "hands" to accomplish complex tasks.
