That's funny! Tell me, have you tried posting a link on the Joomlaworks forum?
You can try. It's not possible.
But please take a look at the link of the previous post. That link leads to a page of a commercial extension that could be a K2 replacement. And this link works fine.
I hope now you understand why the developer of K2 leaves users of his component without updates?

I recommend all users of the K2 component to use the unofficial version - K2forJ4. The K2 developer has done a disgusting thing by deceiving those who trusted him.

So, I just migrated to Joomla 4 using the K2forJ4 on github.   And - so far, so good.  It seems to be working! 

With all the drama, fuss and delays from JoomlaWorks regarding J4, it amazes me that someone else just quietly developed this and is making it available for free.  They are responding to and fixing issues with it as well (I haven't had any yet). 

Anyway, just a note to encourage anyone who might be thinking about trying it.  My biggest fear at this point is that I will eventually need to migrate to core content anyway, and the migration tools are exclusively for J!3.  But, I needed to get this done - and it actually turned out to be easy. 

After the last updates the K2forJ4 from eworkers github is running with no issues on my site.

Hello Fotis how are you? Have you got any news for Joomla 5 and K2? Can we hope for update and if yes do you think that it is close?

There is a new rolling release!! It gives us hope!

New rolling release is a good sign indeed!

Where can I find the rolling release?

Hi.

I would like to ask those who have upgraded k2 to J4 version if they use any k2 modules (like news rotation etc). Do they work after the upgrade?
I noticed that all k2 extensions in joomla extensions are only compatible with j3 version.

Thank you.

I use the K2 content modules a lot, and the K2forJ4 versions are working fine. But, basically all 3rd party extensions have (obviously) dropped integration with K2 since it does not "officially" exist for J4. So, it depends what modules etc you are using.
