Board 15.1 introduces major enhancements across **Board AI Agents, Operational Forecasting, the Board for Microsoft 365 Excel Add-in, the planner experience, and Platform administration**. This release expands the production capabilities of Board AI with interactive Agent experiences and business-aware Dataset Attributes. It also introduces new forecasting capabilities, enhances the Board for Microsoft 365 Excel Add-in, and delivers improvements to planning, reporting, security, and centralized administration. ## Main new features of Board 15.1 ### Board AI Agents Board introduces V3 to [Board AI Agents](/v15/docs/board-ai-agents) with faster performance for complex analyses by running independent tasks across multiple Entities, Datasets, or steps in parallel. Users can sort, filter, and pin columns in Agent-generated tables, copy data, export results to Excel, or send table content to a Smart Import Object for review. V3 also applies resolved Dynamic Selections from the Screen, but not manual Selection changes made in Play Mode. V3 requires Board platform version 15.1 or later. Users can now work with interactive Agent tables, export results, and send table content to a Smart Import Object for review. Board 15.1 also adds Agent version management, support for resolved Dynamic Selection values, broader access through the “GenAI” permission, and API Credit monitoring in Subscription Hub. --- ## Board for Microsoft 365 Excel Add-in Board 15.1 continues to enhance the [Board for Microsoft 365 Excel Add-in with improvements](/v15/docs/board-for-m365-excel-add-in-enhancements-15-1) to usability, migration, and reporting.

The new “Data Attributes Table” lets Developers add business-friendly descriptions to the Algorithms, Entities, Cubes, Rules, and Rankings used in a Dataset. Developers can also reuse suggested descriptions for the same Entity or Cube from other Datasets. These improvements make Dataset content easier to understand and help Board AI Agents interpret business terms with the correct context. For more information, see [Datasets improvements](/v15/docs/datasets-improvements). --- ## Other enhancements Board 15.1 also introduces several [additional improvements](/v15/docs/other-enhancements-15-1), including: - Numerous usability, performance, security, and reliability improvements throughout the Platform **MS Office Excel Add-in required with the Subscription Hub 15.1 update** Installing Board 15.1 in any environment under a Subscription Hub, including a sandbox, updates the Subscription Hub to its latest version. After the update, **MS Office Excel Add-in desktop versions earlier than 15.1 cannot connect to production or other environments under the same Subscription Hub,** except version 14.5.5, which remains compatible for customers using Board 14.5. Customers using Board 14.5 can update the MS Office Excel Add-in to version 14.5.5 to maintain connectivity while planning their transition to Board 15.1. Earlier MS Office Excel Add-in versions do not have an available fix. This does not affect the [Microsoft M365 Excel Add-in](/v15/docs/about-board-for-microsoft360-excel-add-in). ## Related - [What's new in the Board 15.0 release?](/whats-new-in-the-board-15-release.md) - [Board License types and add-ons](/board-license-types-and-add-ons.md) - [The new Board M365 Excel Add-in](/the-new-board-m365-excel-add-in.md)
