Changes in LWC Framework that Affect Component Behavior

Every Salesforce release increments the API version of the LWC framework. Versioning your components insulates you from unexpected changes, but also limits access to new features. Keep yourself in the loop on LWC changes over time.

Component-Level Features

To see what’s changed in LWC in the latest Salesforce release, see the release notes. Changes that apply to a specific apiVersion are described separately from changes that affect all versions of LWC.

Component-Level Breaking Changes

Component-level breaking changes apply to custom components for Lightning Experience, Experience Builder sites, and the Salesforce mobile app.

LWC developers who use LWC outside of the Salesforce platform are impacted by additional breaking changes. For more information, see LWC OSS v8.0.0.

Release Preview

This release is in preview. Features described here don't become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can't guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.
