I see no mention of the bug where mail.app will take accounts offline randomly in 10.14.4.

Apple said this was being addressed. Extremely annoying problem. Hope it is missing from the changelog.

It's curious that, to me, it only happens with a Gmail account I have. Other accounts (GMX, iCloud, Office365) work without hiccups.

I hope this does something about battery usage that seems to have increased since the last update.
