Updating Php Storm - Mac Osx

I am sure this is a stupid question but is there any way to just update the existing installation, or do i always have to basically install the new version and then delete the old version ?
Do the settings remain ?

Thanks in advance


Well, yes.
The only way to update "current installation" is via Settings|Check for update. Updates are usually available between sequental releases and EAP builds.
App settings and local history reside inside users Library folder.
