It is now a compositor node only. You'll have to go to the compositor and add the glare node, set to bloom. Then back in the viewport you'll have to activate the viewport-compositor under the viewport shading tab. Set to either camera or always, depending on if you always want to see it or just in camera view.

Hopefully they'll put it back as it was before, they put a developer on it and we get it on some future Blender version. This is why we donate a few bucks to Blender's development fund.
