Weekly Update 2 February 2026 - SPFx Update, User Config API, Channel Apps update, Dev Proxy v2.1

This week: SharePoint Framework (SPFx) roadmap update – January 2026 https://devblogs.microsoft.com/microsoft365dev/sharepoint-framework-spfx-roadmap-update-january-2026?WT.mc_id=M365-MVP-5001530 Introducing the Microsoft Graph User Configuration API (preview) https://devblogs.microsoft.com/microsoft365dev/introducing-the-microsoft-graph-user-configuration-api-preview?WT.mc_id=M365-MVP-5001530 Apps for shared and private channels https://learn.microsoft.com/en-us/microsoftteams/platform/build-apps-for-shared-private-channels?tabs=tabs%2Cexternal-users%2Csharedchannel&WT.mc_id=M365-MVP-5001530 Dev Proxy v2.1 with configuration hot reload and stdio proxying https://devblogs.microsoft.com/microsoft365dev/dev-proxy-v2-1-with-configuration-hot-reload-and-stdio-proxying?WT.mc_id=M365-MVP-5001530 This week we're seeing some momentum again in the Microsoft ecosystem, and I'm excited to share a few highlights. First, the SharePoint Framework (SPFx) team has delivered against their January roadmap goals with the debug toolbar update, which is a promising sign of continued investment. It’s great to see action following communication, reinforcing confidence in the platform’s future. We also saw Microsoft Graph ship a long-awaited beta API: the userConfiguration endpoint. This API supports mailbox folder-specific settings, offering CRUD operations for configuration alongside Exchange Online items. It could be the missing piece for those still stuck on EWA due to Graph’s previous feature gaps. On the Teams front, apps are now generally available within shared channels, and private channels support is in public developer preview. This helps close long-standing functionality gaps and supports richer app experiences across all Teams channel types. Finally, Dev Proxy 2.1.0 is here, and it’s a great one. Alongside quality-of-life improvements like hot reload, it now supports stdio proxying which means you can now use it with MCP servers, not just web traffic. This broadens the tool’s use case significantly, especially for developers working with modern connected platform applications. Overall, a solid week of progress worth noting, have a great rest of your week! 👋 Just starting out, or here for the first time? Welcome!
