Cant find the Kodi update 17.1 Stable

Hi: I am really new at this. I’ve been getting a message the last few days to do an update to Kodi 17.1 Stable.
I currently have Kodi 17.1-RC1 dated in Feb 2017. I went to Kodi tv, downloads, but couldn’t find anything called Stable. So I went to Google play store and clicked on the Kodi app logo and it said uninstall or update. So I updated. Now the build says Kodi 17.1 (no RC-1) and march 28, 2017.

So am I on the right track?? Everything went fine. Seems stable……I other thing I worry about is Kodi offered a 64 bit update and I don’t know what Goggle’s is and my core is 64 bit.

Oh and one more thing, Do I really need to uninstall the old version first?? Because I didn’t. We all update other programs in the tech world and you don’t….

Thanks in advance for any advice or words of comfort.
