There are a lot of breaking changes, several undocumented, and a major security regression (I was told they will merge, in discord by the dev team)

I do not like the direction they are taking and switched to pi

If you want to stay with opencode, I would wait a while for things to settle, every plugin has to migrate before they will work, if they can, things have changed.
