For a comprehensive overview; see the complete list of new features on our website: Whats New in Oxygen AI Positron 8.1. There is also an Eclipse plugin distribution of Oxygen AI Positron that contains a subset of the Desktop functionality.$$$Sensitive Data Masking for AI Requests$$$Personal or private information (such as email addresses; phone numbers; IDs; or API keys) is now automatically identified and masked in AI requests to help protect sensitive data. You can extend this protection by adding custom patterns to cover additional data types. The masked information is automatically restored in the AI response; ensuring that users see the correct content and that any generated or updated files remain accurate.$$$Sensitive Data Masking for AI Requests$$$Improved Review Experience for AI-Modified Files$$$All files created or modified by AI now appear directly in the chat area; so you can review the proposed changes and accept or discard them without leaving the conversation. You can also open each file individually and accept only a subset of the proposed changes while rejecting the rest.$$$Improved Review Experience for AI-Modified Files$$$Optimized Token Consumption for AI Prompts and Tools$$$The prompts and tools that the AI uses to generate answers have been improved to consume fewer tokens/credits.$$$New Planner Chat Mode for Resource-Consuming Tasks$$$The newly introduced Planner chat mode is available for complex; token-intensive operations (e.g.; “Translate all files in the current folder” or “Find all conrefs and replace them with conkeyrefs in userguide.ditamap”).$$$$$$After being given the prompt; the AI explores your project; proposes a multi-step plan; and; after your approval; delegates each step to the most suitable AI agent. This means large; project-wide changes can be coordinated without hitting LLM context limits; while still showing you the tool calls and results for review.$$$$$$New Planner Chat Mode for Memory Consuming Actions$$$Smarter PDF/Word Attachment Expansion in Planner Mode$$$When using the Planner chat mode with PDF or Word (.docx) attachments; the document is automatically split into multiple Markdown files; with embedded images extracted into a temporary folder. This allows the Planner to invoke sub-agents that can process; transform; or convert the extracted files and assets as needed (for example; converting them to other formats or generating new project structures).$$$More Context Information Available in Chat$$$The AI chat now automatically includes additional information about your environment and editing context; such as the Oxygen application version; operating system details; current date; main file information; and caret or selection data (Oxygen 28.1 or newer). Having richer contextual information leads to higher-quality AI responses. For example; when the AI needs to run a command-line tool; knowing whether you are using Windows or macOS is essential to generate correct and relevant commands.$$$Tools Selector$$$You can now customize the AIs capabilities for each chat mode. The new Tools selector allows you to disable or enable specific tools (either added vi
