Garmin forerunner 965 software version 22.24

Hi, 

I have a question. Since the issues surrounding garmin models last month I have disabled auto-update.

This morning I looked through the software versions and saw 22.24 was available.

My device however, isn't showing any updates with message 'no updates available' but a colleague does have this version (he disabled auto-update as well).

Are the versions gradually pushed or is there another explanation?

Thanks in advance!
