The Salesforce Developer’s Guide to the Spring ’26 Release
Summary
The Spring ’26 release brings major developer enhancements to Lightning Web Components, Apex, and the Agentforce platform that streamline advanced customization and coding. You can now dynamically attach event listeners in LWCs, execute GraphQL mutations, and fully leverage TypeScript with base components for better code quality. Apex gains powerful cursor-based processing for large datasets, a simple method for fetching record-type-specific picklist values, and improved PDF rendering with Blob.toPdf(). Agentforce introduces new low-code and pro-code tools to build and test AI-powered agents with deterministic logic and advanced debugging. Plus, the Salesforce CLI and Developer Tools get features to speed deployments and testing. These updates help Salesforce teams build more efficient, scalable, and maintainable apps customized to complex business needs.

The Spring ’26 release is rolling out to your sandbox and production environments starting this month and continuing through February 2026. Get ready, because this release is packed with product updates, and new features to enhance your development experience. In this post, we’ll take a look at the highlights for developers across Lightning Web Components (LWC), Apex, Agentforce, Agentforce Vibes, Data 360, Agentforce 360 Platform developer tools, and APIs. LWC updates in the Spring ’26 Release The Spring ’ 26 release introduces several quality-of-life improvements for LWC developers. These updates range from new ways to handle user actions to full support for modern coding tools like TypeScript. Dynamic event listeners Before this release, you had to list every single event handler (like onclick or onmouseenter ) directly in your HTML template. If you wanted to change how a component reacted to a user at runtime, you often had to use complex workarounds.
