# Upgrading Chrome Checklist
This document is meant to serve as an overview of what steps are needed
on each Chrome upgrade in Electron.
These are things to do in addition to updating the Electron code for any
Chrome/Node API changes.
- Verify the new Chrome version is available from
https://github.com/zcbenz/chromium-source-tarball/releases
- Update the `VERSION` file at the root of the `electron/libchromiumcontent`
repository
- Update the `CLANG_REVISION` in `script/update-clang.sh` to match the version
Chrome is using in `libchromiumcontent/src/tools/clang/scripts/update.py`
- Upgrade `vendor/node` to the Node release that corresponds to the v8 version
being used in the new Chrome release. See the v8 versions in Node on
https://nodejs.org/en/download/releases for more details
- Upgrade `vendor/crashpad` for any crash reporter changes needed
- Upgrade `vendor/depot_tools` for any build tools changes needed
- Update the `libchromiumcontent` SHA-1 to download in `script/lib/config.py`
