Vlad Actually the current "stable" version can be used in Orion without issue. Just there is an bug issue in it so I don't want to recommend 2.17.0
Violentmonkey is updating frequently. The "stable" version might be not actually "stable".
2.18.0 might come after weeks or months.
Indeed Orion is also BETA as per https://kagi.com/orion/ haha. I don't think there would be any issue if we know a specific version is much reliable than the latest one.
