DSystem

I think it's because you are not interested in developing the market. I see a trend to close the community in the future in the cloud with paying customers, they are more profitable. IMHO. One of the advantages of IPS was its good extensibility and variety of applications and extensions.
 
 
 

No issues there. He won't be able to upgrade 2/3 of them. Lots of time saved! 😂
 
Seriously, I have several apps and plugins extending classes in the /system folder. That means they're all dead for v5. So far, I don't like the direction v5 is taking at all. No matter what awesome tools you may have in place, being unable to overload (almost) all classes like before is a huge issue.
 
Well, that's it for me for now. I won't say anything further until there is more info about those "awesome tools" you mentioned. But I don't have much hope for them.

They will be there for a couple of years for those who won’t jump in V5 right away.
File edits will be back with resources being sold in dev’s board. And for those who use marketplace and can’t use FTP, will get limited resources.
But there’s no doubt it will be the end of this marketplace and I truly believe that’s what IPS is after for a while now.
I haven’t decided yet if I will keep developing for IPS, as I told somewhere else… and I must confess the answer its getting clear at every blog entry. 
Anyway, if I remain, certainly will reduce from 300 to 50 maximum, due to… framework limitations. 😂

Will stick with IPS4, maybe until IPS version 6 🙃🤦‍♂️

Thank you. 👏👍
Still, remove the ability to hook is a huge step back and will make marketplace even worse and smaller but I guess that’s the point after all. A massive number of resources are dead.
We’re basically back to IP.Board 2 (file edits will be required for custom jobs as we can’t hook) and IP.Board 3 (back to hook points era). 
Anyway, just my feedback. Not trying to annoy anyone; just my honest feedback.
Tks.

That will be dealt with in UIExtensions. We're wrapping some things up on those before the blog entry, but it's coming.
We will be removing the block on base classes and you'll be able to add listeners to \IPS\Content\Item (or Comment or Review).

So the answer is no as there is no HOOKS tab anymore. So resources from now on will extend only official apps that I have in my license. If the user has another 3rd-party resource, it won’t work anymore because I don’t have all the marketplace resources out there to add listeners since it checks for the class. 
Great improvement.
