How to get current release version now that OmahaProxy is down

[Sam Warfield]

According to the V8 release docs OmahaProxy is how to get the current release version for V8. Omaha has been taken offline and the replacement site only reports Chrome versions, not V8. What is the best place to pull the current beta version from?

Hi Sam,

Thanks for raising the Q. I'll update the documentation asap. In the meantime:

1) To get the current beta version please navigate to: https://chromiumdash.appspot.com/releases, find the latest Beta and click on the (i).

Following the V8 githash link now to -> https://chromium.googlesource.com/v8/v8.git/+/5eefc590c868d8dfb411e53053c963fe42dcda74 is showing you the V8 version: 'Version 12.0.267.8'

2) In case you're interested when to expect a new version, PTAL at the release schedule

Cheers,

Lutz Vahl

Thanks for the help Lutz, I'm looking for a more automated approach. We've got tooling that automatically scans for the newest version so we automatically pull in security patches as fast as possible. This was easy on the old Omaha Proxy since it returned a JSON payload with the version number. Is there an endpoint that returns only the version number, not the whole source that would need to be parsed?

[Sam Warfield]

This is what we were doing previously, we're looking for a drop in replacement query.

curl -s 'https://omahaproxy.appspot.com/all.json?os=linux&channel=beta' |

jq -r '.[].versions[].v8_version' |

egrep -o '^[0-9]+\.[0-9]+\.[0-9]+(\.[0-9]+)?\b'

This issue was raised in the original Omaha Deprication but never fixed.

Hi Sam,

You can use the JSON api of chromiumdash:

https://chromiumdash.appspot.com/fetch_releases?platform=Win32&channel=dev

I think there are a couple of more filtering params you can use (and it lists everything if you omit them).

Hope this works.

cheers

That works for getting a hash, but we need the tag without relying on parsing that page (Too liable to change) or downloading the whole repository and using git describe to pull the tag.

[Leszek Swirski]

You can pipe the chromium version to fetch_version to get the v8_version, e.g.

curl "https://chromiumdash.appspot.com/fetch_version?version=$(curl 'https://chromiumdash.appspot.com/fetch_releases?platform=Win32&channel=beta' | jq -r '.[0].version')" | jq -r .v8_version
