Actually, it does on https://github.com/dnnsof.../releases/tag/v9.8.0

But not visually attractive :-) 

If you want in v9.8.0 to remove the Telerik library, here are the steps to do so (please note this may also break any other 3rd party module that depends on Telerik):

1. Take a full backup of the site and database.
2. In Extensions > Available Extensions > Modules : Install the Resource Manager module.
3. Navigate to Site Assets, remove the Digital Assets manager module from the page, insert an instance of the Resource Manager.
4. Repeat step 3 but for the Global Assets page.
5. In SQL Console Run the following command:

<code>UPDATE {databaseOwner}{objectQualifier}Packages
SET IsSystemPackage = 0
WHERE Name IN ('DigitalAssetsManagement', 'DotNetNuke.Telerik.Web', 'DotNetNuke.Web.Deprecated', 'DotNetNuke.Website.Deprecated')
</code>

6. Go to Servers and Clear cache.
7. In Extensions > Modules , uninstall <code>Digital Assets Manager</code> (Tick delete files).
8. In Extensions > Libraries, uninstall <code>DotNetNuke Telerik Web Components</code> (Tick delete files).
9. In Extensions > Libraries, uninstall <code>DNN Deprecated Web Controls Library</code> (Tick delete files).
10. In Extensions > Libraries, uninstall <code>DotNetNuke Deprecated Website Codebehind files</code> (Tick delete files).
11. Open the web.config file and search for Telerik, delete any lines that reference it.
12. Verify in bin folder, there is no dlls including the word Telerik.
13. Test your 3rd party modules to make sure they still work without Telerik.

Since it said "want in v9.8.0 to remove the Telerik library", I presumed those instructions would not apply if you were not ready to remove Telerik.
Is it possible to perform only steps 1-7 and keep the Telerik-dependent modules for awhile and still have the new Resource Manager?

Also, in step 9:

" In Extensions > Libraries, uninstall <code>DNN Deprecated Web Controls Library</code> (Tick delete files). "

There is no Delete button for that, just a pencil for editing, but no trash can. Editing does not show a Delete button either.

Is there some way to enable Delete for that library?

 

Can you confirm that you completed Steps 5 and 6? By doing so, you should then see the checkbox to delete the files since it won't be marked as a system extension.

Yes, confirmed. I ran the SQL script again and cleared cache again just to be sure, but no change for the Library called:
DNN Deprecated Web Controls Library
Just the pencil icon.

I just went into SSMS and checked the record for 'DotNetNuke.Web.Deprecated' and the field called 'IsSystemPackage' is definitely set to zero. However, the 'FolderName' field is empty!

Take a look at DNNDave's https://youtu.be/JNgXXSOQBTs recorded earlier today. It has all of the details on how to do the manual removal of the Telerik stuff.

i have the same Problem here with different Installation...
There is no Delete button for that, just a pencil for editing, but no trash can. Editing does not show a Delete button either.

i make all the steps but no chanche to delete DNN Deprecated Web Controls Library
shows only a pencil...

I had the same problem, because of an old dependency between HTML-module and "DNN Deprecated Web Controls Library", which is probably a legacy entry in the table "PackageDependencies" since DNN7 or earlier.

You can check it by running this SQL command "EXEC GetPackageDependencies".

In my case, deleting the record in PackageDependencies solved it and let me remove "DNN Deprecated Web Controls Library" by clicking the trash-icon.
