SharePoint Framework 1.23 Reaches General Availability

Published: 12 June 2026. Source: Microsoft 365 Developer Blog: SharePoint Framework (SPFx) Roadmap Update, May 2026

Microsoft confirmed on 28 May 2026 that SharePoint Framework (SPFx) version 1.23 is now generally available. For most SharePoint Online tenants this is a background platform update: SPFx solutions run on the version Microsoft controls, not one admins select. What matters is understanding which new capabilities are now stable, which near-term changes carry governance implications, and where the roadmap creates a planning window for organisations that depend on custom solutions.

What SPFx 1.23 Adds

The primary developer-facing addition in SPFx 1.23 is grouping support for ListView Command Sets. Custom toolbar buttons built using this extensibility point can now appear in the grouped-view command bar, a context that prior versions could not reach. If your tenant has custom list toolbars or library actions maintained by an internal team or a vendor, those solutions may take advantage of this new surface area once the developer updates their package. No admin configuration is required.

Version 1.23 also ships a public preview of the new SPFx CLI, intended to replace the Yeoman generator as the primary scaffolding tool for new SPFx projects. The existing Yeoman workflow remains fully supported. The SPFx CLI will reach general availability in SPFx 1.25, targeted for September 2026, at which point the Yeoman generator receives its final update.

Near-Term Changes With Direct Admin Relevance

Two updates scheduled for June 2026 carry more direct governance implications than the 1.23 feature set itself.

Edit and new panel overrides (SPFx 1.23.1, June 2026). This update allows custom SPFx solutions to replace the default new-item and edit-item forms in modern SharePoint lists. Any account with site-owner access or higher that can deploy solutions to the app catalogue could use this capability to alter the data-entry experience on any list on that site. Before 1.23.1 lands, confirm which accounts hold site-owner permissions on lists that handle sensitive or regulated data. A permissions audit using Report Master is the recommended starting point.

AI feature public preview (SPFx 1.24, June 2026). Microsoft has signalled an AI-focused capability moving from internal to public preview in the 1.24 release. No feature specification has been published as of this writing. Watch the Microsoft 365 admin centre Message centre for the relevant MC notification when it arrives.

React 18 Timeline: No Longer June 2026

React 18 support for SPFx was previously targeted for June 2026. The May 2026 roadmap update removes that commitment. Microsoft states it is still working through its own out-of-the-box web parts and cannot confirm a revised schedule. Organisations that had planned to validate or migrate custom SPFx solutions to React 18 during this window should treat the timeline as open until a new target is published by Microsoft.

Note: React 18 is a framework dependency for developers building or maintaining SPFx solutions, not a setting administrators configure directly. Your action here is to inform whoever maintains your custom SPFx solutions so they can adjust their project timelines accordingly.

Recommended Admin Actions

  1. Review the tenant app catalogue. In the SharePoint admin centre, navigate to More features > Apps. Identify which deployed solutions use ListView Command Sets; those solutions are now able to target grouped views following the SPFx 1.23 update.
  2. Check per-site app deployment settings. On sites where end users can deploy apps directly (via Site contents > New > App), a developer could deploy an edit-panel override solution after SPFx 1.23.1 ships. Review which sites have this setting enabled and restrict it on sites that handle sensitive or regulated content. Report Master can export a full permission matrix so you can see at a glance which sites expose elevated access to a wide user base.
  3. Notify solution developers and vendors. Communicate that the React 18 timeline is no longer June 2026 and that no new target date has been set. Teams with solutions scheduled for React 18 validation in Q2 2026 should adjust their planning accordingly.
