Don't push updates on Friday.

Friday afternoons are a terrible time to push updates for a weekday shop. Is your deployment team fresh out of school?

You are making the assumption that they care about the quality of their product or the experience of their customers.

From their track record I’m not sure this is a good assumption to make.

Would be nice if they were at least accompanied with patch notes.

Patch notes are usually posted on this forum in its respective category.
