All stacks can update via the auto updater. If they do not it is because the developer has not enabled it. @Jannis and myself have often offered help to new developers if they are unsure on how to implement this.
The only other reason not to auto update is to withdraw updates after a certain period of time in order to re-charge customers for new versions. This is not a stance that is supported by this forum and if developers want the resultant income from that approach then they can use email or their own forum.
Also remember that there are a relatively small number of people on this forum and so other methods would be necessary any way.
This is a privately funded forum. Developers can pay to set up their own forum and do whatever they want.
Using a forum which you are not in control of as a publication device for release notes (updates bug fixes etc) is a disservice to your customers.
This entire thing could be gone in a day and there would be no reference or back catalogue of release notes, no business should run like that. Most developers run a simple release notes archive on their sites - this is the proper way to do it. There is no argument to be made that the developer is small or new, I did all these things from the start and I don’t charge a penny for my stacks. It is just the right thing to do.
Can we now stop debating such minutia and get on using this place as a user focussed question arena to help people.
