By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers.md). Updated 2026-10-22. - ID: DSK-9 - Level: Recommended - Chapter: [Update integrity](https://agentwranglers.se/playbook/desktop-apps/update-integrity.md) - Rule: When the app ships its own browser engine, as Electron does, move to each new major version within 8 weeks of its release. Never ship on a version its makers no longer patch. - Check: A CI step compares the app's Electron major version with the newest three on the Electron release list. It fails when the app's version is older than all three. - How: Electron bundles Chromium and Node.js, so every browser hole is a hole in your app until you update. Electron patches only its newest three major versions. Tauri and native web views use the engine the operating system updates, which moves this work to the user's system updates. Let a dependency bot open the upgrade, as [update dependencies in small automatic steps](https://agentwranglers.se/playbook/engineering/version-control-and-review/automated-dependency-updates.md) says. Test the upgrade on every platform you ship. ## Sources - [Electron release timelines](https://www.electronjs.org/docs/latest/tutorial/electron-timelines) - [Electron security checklist](https://www.electronjs.org/docs/latest/tutorial/security) ## Related rules - ENG-18 [Update dependencies in small automatic steps](https://agentwranglers.se/playbook/engineering/version-control-and-review/automated-dependency-updates.md) in Engineering **For agents:** this playbook is free to use under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/), which requires credit with a link.
