Breaking & API Changes​

Below are breaking changes introduced in Electron 21.

V8 Memory Cage Enabled​

Electron 21 enables V8 sandboxed pointers, following Chrome's decision to do the same in Chrome 103. This has some implications for native modules. This feature has performance and security benefits, but also places some new restrictions on native modules, e.g. use of ArrayBuffers that point to external ("off-heap") memory. Please see this blog post for more information. #34724

Refactored webContents.printToPDF​

Refactored webContents.printToPDF to align with Chromium's headless implementation. See #33654 for more information.

More information about these and future changes can be found on the Planned Breaking Changes page.

End of Support for 18.x.y​

Electron 18.x.y has reached end-of-support as per the project's support policy. Developers and applications are encouraged to upgrade to a newer version of Electron.
