Why I can't update my android version on Samsung Galaxy Alpha from 4.4.4 to 5.0?

[AC Question]

Every time I push to check for updates it says the software is up to date is there anywhere special that I need to download the new android version?

Welcome to Android Central! Availability of an official update depends on both the manufacturer and the carrier. If neither has developed an official update, then you won't get one.

It doesn't look like Samsung came out with a higher version. You can check here and input the exact model number: Firmwares - SamMobile
