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.

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 apply to custom components for Lightning Experience, Experience Builder sites, and the Salesforce mobile app.

• v63.0
• v62.0
• v61.0
• v60.0
• v59.0

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.
