Noticing the same thing watching traffic. It's been downloading a little over 2GB per day and no update to show for it. Just got another one today, but am still on 2020.24.6.4.
I've had one update the last month (maybe 2 max), and the usage from June 15th to July 14th was 78.7 GB download and 8GB Upload.
Are these hotfixes to current release without versioning?
