Even better: Increase the thumbnail size in the database settings. The default is rather small (200x200 pixels). 
Note: This change only affects new uploads. 

Moving between categories is an admin option both on the front- and the back-end. You just click “move”. 
Changing the publishing date depends on the field “publishing date” being activated in the field settings. 

I used the same method. I guess the problem is that those mail providers can just add new domains every week and the block list is never up to date. 
But I still appreciate the feature. It certainly helps to reduce those registrations. 

I had the same experience. It was actually hard to find a temporary email domain that was successfully blocked. But it does work. 

Support is handled manually here via PM or through my site. For a support request, the purchase key should be added to the request. I have no plans of moving my products and their purchases to my site at the moment. I don’t really expect further sales or support issues to justify this. I will just deal with the few request that might come in manually. 
I might start offering 5.x products on my site if what I do is still possible with 5.x. We will see. 

Is the Pages (and Commerce) documentation still on the way? Only Core, Forums, Gallery and Blogs are documented at present.
Thank you!

You can ignore the modification indication and the default state. That refers to IPS’ default templates, which are irrelevant for custom templates. If you do anything on these screens, you replace the SuperGrid code with the default IPS code. You will hardly ever want that. 
If you never touched the templates, you can always just upgrade the plugin (carrying the templates) and the templates are updated when needed. 
You only need to deal with these code comparisons if you manually made change to the templates. In this case, the upgrade will prompt a code comparison where you would need to decide if you want to keep your own lines or have them replaced with the templates in the plugins. 

There is a Deleted Content section in the ModCP to do this. 
However, it only works if the “Permanently delete content” setting in the ACP ist not set to “immediately”. 

I can’t speak for IPS, but it’s still safe to say that this is extremely unlikely.
The people with coding skills don’t need it. They can just open the respective page, inspect the actual HTML and learn everything they need from it. It’s all public and there for everyone to see. 
The people who don’t have these skills, can’t do much with such a tutorial. They would just have to copy code they don’t understand. If they make the slightest mistake, everything breaks and now someone has to give free support for the tutorial. Who is willing to do that? If the user wants just a tiny variation of the template, they would have no idea how to do it. So again, they would ask for free support. Not to mention that such custom Pages templates correspond to Pages database fields and possibly CSS and JS files. If they don’t exist as expected, again, everything breaks. It just doesn’t work. I’ve created an entire online course around learning Pages, but it does not contain teaching people how to create templates from scratch. That’s just not a suitable topic for a tutorial. Either you know how to do it or you can get stock or custom products which deliver the needed functionality. There really is no middle ground.

Well …

Looking at my sites, it seems like spammers are already using it. I get more and more replies to old topics which somehow are on topic but still somehow make so little sense that I can’t believe a human registered to post it. 
I’m not afraid of AI and use it myself, but only like a brainstorming partner, where I judge which replies are actually useful and correct. I can’t imagine having AI (auto) reply/publish anything on my sites at the moment. And I think it would only dilute the value of a community. Because the AI answers will soon be available directly within search engines and other apps and services. I rather run the place where answers can be different and better than that. 

I'd recommend having a read of this - Google is specific in there that you shouldn't be using cloaking for paywalled content, and that you should be using structured data for it instead.

Have you read the article you linked? It explains in details why should NOT do it.

Yes, you can do it there. Changes there are global, but you can target the specific fields. 
It’s a bit tricky to try things out there as the code only takes effect when a new record is submitted. 

Improvements are nice, but my main concern is maintaining existing projects. I would want to know everything that is not possible anymore and learn if there are alternative ways. This includes hacky solutions like putting a MySQL query in a theme template and things like that. I have lots of customized installations and I don’t want them to be stuck with 4.x.

Users would need to use the Forgot Password function to set a password and would need to know the email address they used with the linked login method. So you could or should explain that somewhere and inform your users before making the switch. 

Been doing that for quite a while across all my communities.
