Electron 35.0.0 | Electron

Service Worker Preload Scripts for Improved Extensions Support Originally proposed in RFC #8 by @samuelmaddock, Electron 35 adds the ability to attach a preload script to Service Workers. With Chrome's Manifest V3 Extensions routing a lot of work through extension service workers, this feature fills in a gap in Electron's support for modern Chrome extensions. When registering a preload script programmatically at the Session level, you can now specifically apply it to Service Worker contexts with the ses.registerPreloadScript(script) API.
