Hello everyone, We are proud to announce the immediate availability of the *Oxygen AI Positron 8.3* plugins for all our 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. Version *8.3* introduces stronger enterprise AI governance, a new project-aware development agent mode, expanded AI model support, and new XML automation capabilities. The release gives technical writers, XML developers, information architects, and enterprise administrators more control over AI behavior while improving assistance for technologies such as XSLT, Schematron, XPath, and DITA. *What's New in Oxygen AI Positron 8.3* ******************************** * *AI Governance with Event Hooks* Organizations can now monitor and control AI-driven workflows more closely with the introduction of a hook system for intercepting AI events, offering improved visibility and control over AI-driven workflows. Organizations can use hooks to audit AI activity, enforce governance policies, collect usage metrics, or block potentially risky operations before they are executed. To simplify integration with existing enterprise tooling, the new *Oxygen AI Positron Hooks* add-on lets teams run external scripts when specific AI hook events occur. This makes it easier for administrators to connect AI lifecycle events to auditing, analytics, policy enforcement, and workflow automation systems. * *Dev Agent Chat Mode for XML Development Projects* The new *Dev Agent* chat mode gives XML teams a project-aware AI assistant for development tasks such as XSLT, Schematron, XPath, validation, and transformations. The Dev Agent can explore the project, propose a plan, and perform project-wide changes, while you remain in control of reviewing and deciding which modifications to keep. * *Specialized Development Skills* Version 8.3 adds specialized skills for development vocabularies including *XSLT*, *XSD*, *Schematron*, and *XSpec*. These skills help the AI produce more accurate code suggestions and reduce errors, enabling faster and more efficient development. Custom skills can also now be packaged as ZIP archives with the /.skill/ file extension. Once placed in the configured skills folders, these packages are automatically recognized and loaded by AI Positron, making it easier for you to distribute and share custom AI capabilities. * *Expanded Enterprise AI Connectivity* Organizations can now access newer OpenAI reasoning models through a new *OpenAI Responses* enterprise connector. Version 8.3 also adds support for connecting to *Model Context Protocol (MCP)* HTTP servers that use OAuth authentication. You can view a summary of running or failed servers in the /Connection status/ section, with integrated login and logout controls. For AWS users, the *AWS Bedrock* connector now supports *AWS Credentials (Profile/SSO)*, offering a more secure authentication option than API keys. * *New AI Models and Improved Reasoning Visibility * Oxygen AI Positron 8.3 expands the list of available AI models for AI-assisted tasks, including:  - *GPT-5.4 Thinking*, *GPT-5.5,* and *GPT-5.5 Thinking* through the Positron Service or an OpenAI Responses enterprise connection.  - *Claude Opus 4.8 Thinking* and *Claude Opus 4.8*, designed for agentic workflows and complex multi-step tasks.  - *Gemini 3.5 Flash* through the Positron Service or the Vertex AI enterprise connection. You can now inspect reasoning from supported OpenAI thinking models in a collapsible chat section, improving transparency without cluttering the conversation. Administrators can also manage which models are available for configured AI connections, define recommended defaults, and add models beyond the predefined list. * *Automatic Conversation Compaction for Longer AI Sessions* Long AI conversations can now continue more smoothly with the new automatic conversation compaction feature. When the allowed context usage reaches 70%, AI Positron summarizes older portions of the conversation and replaces them with a concise recap, preserving relevant context while allowing the discussion to continue. You can disable automatic compaction from the /Preferences/ page or manually trigger compaction using the *Context Consumption* button in the footer of the AI Positron view. * *Fix Multiple Validation Issues at Once* The *AI Positron Fix* action can now be applied to multiple selected validation problems in the /Results/ pane. This allows you to resolve several issues in a single AI-assisted operation, improving productivity when working with large or complex XML documents. * *More Flexible Custom AI Actions* When creating custom AI actions, you can now use Oxygen editor variables in the /prompt_ref/ property. For example, a prompt can reference content from your home folder, and the variable will be expanded automatically. * *New AI Tool Function for XPath Evaluation* AI Positron now includes an /evaluate_xpath/ tool function that helps AI-assisted workflows access structured XML content more precisely. * *New XPath AI Functions for Advanced Automation* Two new AI extension functions, /ai:chat()/ and /ai:resolve-action()/, are now available for XPath-based automation workflows, with full technical details available in the supporting documentation.
