Google Chrome Omahaproxy Deprecated

[psomeren]

A colleague introduced me to Evergreen for the Auto Update of Google Chrome. I've noticed Evergreen is still using the a .JSON-file from Omahaproxy. According to this page https://groups.google.com/a/chromium.org/g/chromium-dev/c/uH-nFrOLWtE, Omahaproxy should not be used any longer. Chromium Dash should be used instead.

I have build my own update mechanism using the URL https://versionhistory.googleapis.com/v1/chrome/platforms/**all**/channels/**all**/versions/**all**/releases, but takes to long and holds to much information. As you can see, you can replace "all" with specifics like this:

https://versionhistory.googleapis.com/v1/chrome/platforms/**win**/channels/**stable**/versions/all/releases

Which is much faster, as it only shows Platform Windows and Channel Stable.

The current version of Evergreen is using https://versionhistory.googleapis.com/v1/chrome/platforms to get Chrome version details.
