Kint does not work with latest Devel module 5.4.0

I am pasting in here one of the 3 stack traces that appear in the error logs when
you try to open the devel admin page (as shown in the screenshot above).

This module was made specifically to enhance Devel's Kint integration. Since that has been removed, that would make this module obsolete. Feel free to create issues in the Kint issue queue for any of this module's functionalities that you would want to see in the main Kint module.

Thanks. One more question please.
Is the "main Kint module" this one - https://www.drupal.org/project/kint →
or something else?

Yes, that’s it.

Thanks dieterholvoet! I was able to use the latest version
of this kint module with the latest Devel and I can confirm it
works well.

What is the replacement for ksm() then?

I recommend creating an issue in the Kint → issue queue to add the ksm() functionality.

At some point it might be helpful to have a release of this module that required Devel >= 5.4.0 and the main Kint module

Sure, we could do that. I would still mark the module as obsolete though. MR's are welcome.
