What’s new for SharePoint – September 2025
September was an exciting month for SharePoint and the Microsoft 365 ecosystem, bringing updates that continue to push collaboration and content management forward. The highlight of the month is Knowledge Agent in SharePoint—a game-changing feature that combines intelligent content curation, automated site maintenance, and natural-language workflow creation, all within the SharePoint experience. This innovation aims to make knowledge management smarter and more proactive than ever.
Another major update worth celebrating is the story around SPFx Field Customizers. Microsoft listened to community feedback, and advanced customizations for Microsoft Lists are here to stay. These capabilities complement column formatting, giving developers and power users more flexibility to deliver tailored experiences where JSON formatting options fall short.
This post explores these highlights and other key updates from September, so you can stay ahead and make the most of what’s new in SharePoint and related technologies.
