How can we reach a download URL of a specific version of chromium?

Hi, I'm a maintainer of setup-chrome. I'm planning to support downloading chromium with a specific version number like 119 or 119.0.6045.123. We can download older releases from chromium-browser-snapshots by using the commit position (or also called as chromium revision). The commit position is a unique number and it is used for the directory name in chromium-browser-snapshots.

I leaned we can get the released version number of the chromium from Chromium Dash. But I don't know how to find out the commit position from the version number. Please let me know if you know how to do it. Thank you very much.

Since version 113, you can download revisions from chrome-for-testing, such as https://googlechromelabs.github.io/chrome-for-testing/known-good-versions-with-downloads.json

If you require even more old releases, I don't know proper ways to retrieve them. Previously, I accessed https://omahaproxy.appspot.com/all.json via curl and attempted all possible revisions in descending order until I found the correct version. You can refer to the relevant code here. Also you can check my releases which is tracking revisions since v95

I hope this helps
