Mac OS X 10.10.3 and newer include Photos, which is intended as a replacement for iPhoto and can import its library. If you'd like to go on using iPhoto in addition to or instead of switching to Photos, clickhereand try following the instructions; you'll only be able to do so if you previously associated iPhoto with the Mac App Store.
iPhoto isn’t supposed to and won’t update with Mac OS X, even if it was originally bundled with the computer.

Be aware that support for iPhoto was dropped by Apple over a year ago and is no longer compatible with the Apple Print Products Store. It is partially incompatible with El Capitan, i.e. certain slideshow themes don't work.
The new Photos has much better editing capability. It's biggest difference is that it does not have Events. It uses Moments instead: Moments in Photos are the New Events
