I'm a Donor for at least 10 years now, but I noted "recently" (..joke), I do skip sometimes a update.
Simply as I'm lazy. Too lazy to download and install.
I read that there will be no such feature like a AUTOUPDATER, as different subscriptions exist, understandable no offens.
At least for myself I came up with this solution.
https://github.com/uptoratlen/freeCommanderDownAndUp
What it does?
Not much. It is a Chromedriver based selenium automation script.
And before you ask. Yes, you need still to get a valid login (go and donate some money

(Code is on github)
Check out the Readme on the github page.
You like the idea? But you think I'm missing a certain feature or something is broken?
Fork it, enhance it and sent me the PR. Or open a ticket and I will have a look (simply as I use it myself)
I tested it on two systems and it worked (at least updating 868 was easy ....)
Btw: If you think this is something you do not need, do not use it

If you think this helps you, drop a feedback here.

Cheers
