Show opa version badge in main, and each release doc

[ritazh]

Opa upgrade now comes from framework. Can you try latest commit in master? that is referencing framework that’s using opa v0.35 https://github.com/open-policy-agent/frameworks/pull/167/files#diff-45830b37d8fe6cfa6317672df498ec856ff48ffd48cd2537d18337e6281d6618R14

+1 on showing opa version badge in master, and perhaps for each release doc. thoughts?

Today, you have to go to the last commit for the GK release you are using, from GK go.mod check the framework commit then check framework/constraint's go.mod to see what version of opa that release is using.

+1 for showing up OPA Version being used with respective Gatekeeper release which can solve below problems.

• Safe usage of OPA new features like "future.keywords", new builtin functions, metadata etc..
• Safe Gatekeeper upgrades can be performed without breaking any functionality

Hope this gets addressed soon !!

As part of this issue, can we make sure that this is automated in the future?

[salaxander]
