2. Find the new beta/stable Chromium version from [OmahaProxy](https://omahaproxy.appspot.com/).
3. Put it into the `libchromiumcontent/VERSION` file, then run `$ ./script/update`
- It will probably fail applying patches.
4. Fix `*.patch` files in the `/patches` and `/patches-mas` folders.
5. (Optional) Run a separate script to apply patches (`script/update` uses it internally):
2. Update the Chromium snapshot
- Choose a version number from [OmahaProxy](https://omahaproxy.appspot.com/) and update the `VERSION` file with it
- This can be done manually by visiting OmahaProxy in a browser, or automatically:
- One-liner for the latest stable mac version: `curl -so- https://omahaproxy.appspot.com/mac > VERSION`
- One-liner for the latest win64 beta version: `curl -so- https://omahaproxy.appspot.com/all | grep "win64,beta" | awk -F, 'NR==1{print $3}' > VERSION`
- run `$ ./script/update`
- Time to brew some tea -- this may run for 30m or more.

4. (Optional) Run a separate script to apply patches (`script/update` uses it internally):
- `$ ./script/apply-patches`
- There is also another script `/script/patch.py` that could be more useful
- Check `--help` to learn how it works with `$ ./script/patch.py -h`
6. Run the build when all patches can be applied without errors
5. Run the build when all patches can be applied without errors
- `$ ./script/build`
- If some patches are no longer compatible with the Chromium code, fix compilation errors.
7. When build succeeds, create a `dist` for Electron
6. When build succeeds, create a `dist` for Electron
- `$ ./script/create-dist --no_zip`
- It will create `dist/main` folder in the root of the libcc repo
- You will need it to build Electron.
8. (Optional) Update script contents if there are errors resultant of some files being removed or renamed. (`--no_zip` prevents script from create `dist` archives, you don't need them.)

## Updating Crashpad
If there are any compilation errors related to the Crashpad, it probably means you need to update the fork to a newer revision: see [Upgrading Crashpad](https://github.com/electron/electron/tree/master/docs/development/upgrading-crashpad.md) for instructions on how to do that.

## Verify ffmpeg Support
Electron ships with a version of `ffmpeg` that includes proprietary codecs by default. A version without these codecs is built and distributed with each release as well. Each Chrome upgrade should verify that switching this version is still supported.
You can verify Electron's support for multiple `ffmpeg` builds by loading the following page. It should work with the default `ffmpeg` library distributed with Electron and not work with the `ffmpeg` library built without proprietary codecs.
