why cant I find to google keyboard update 5.0 in the google play store

I see that there is an upgrade for the google keyboard but its not in the google store and I was having difficulty getting the upgrade

Welcome to Android Central! It's a rolling update, so not everyone gets it at the same time. I haven't received the update yet on any of my devices, and I have Nexus devices.

It doesn't appear that anyone else has received it either -- and this is 10 days after the announcement. This is especially annoying since Google just released Gboard for iOS yesterday and THAT app/update is actually available.

FINALLY! The 5.0 update hit my Verizon Galaxy S5 and Galaxy Note 8 today. It was a pain to wait that long after the blizzard of positive press 3 weeks ago but the update is just plain awesome.

Yup, just got it in a flurry of updates on all of my devices as well. Makes me think that it wasn't actually rolling out, but rather might have been held up temporarily due to some minor bugs.
