Q: Photo Update

What have you updated? 

Did you migrate an iPhoto Library or an Aperture Library to the new Photos.app?  Then you are now using a very different application, and it is expected, that the features will be different.

But most of the organization of your Photo Library should have been transferred .  The new Photos for Mac does not have events, but your iPhoto events are available as albums.  Look for a folder "iPhoto Events" with albums inside.

The migration is described here:   How Photos handles content and metadata from iPhoto and Aperture - Apple Support

iPhoto and Aperture are still running on MacOS X 10.11.4.  You just need to update them to the compatible versions Aperture 3.6 or iPhoto 9.6.1.  But sooner or later you will have to migrate your photo libraries to a different application.

See Barney's user tip on how to update iPhoto to version 9.6.1:   Can't Update iPhoto because it is not available in the App Store

And OT's User Tip:  Moments in Photos are the New Events

Like superabound1978 my Photo app corrupted after update 10.11.4 of El Capitano on March 23 2016. I did a "repair" and restore of 23,000 files but all I can see is a list of dates and NO pictures. A second import got me 7000 unimportant faces but NO real pictures.

I cannot find any setting that will allow me to view any file as a picture

what exactly did you do?

A second import got me 7000 unimportant faces but NO real pictures.

This sounds like you imported an old library - you never import a library as it does not work and gives you an giant mess - you open libraries - NEVER import one

You probably will have to restore your backup of the library from before you upgraded and start with that library

Yes , really old - two DAYS prior to the the El Capitano update i.e. the last backup before El Capitano screwed it.

I have no idea what you are getting at

again my post - you answered nothing it ask  --  are you saying that when you restored your library from before the upgrade the exact same thing happened?
