Confusion migrating from 4.8.1 to 5.2.1

[N6REJ]

I'm confused as to what to change to be able to use 5.2.1.
4.8.1 works fine. Something has changed in 5.2.1 that is breaking everything.
I appreciate your help. See can see our code here https://github.com/Bearsampp/module-adminer/tree/5.2.1/bin/adminer5.2.1

Delete plugins/plugin.php and its require. Return an instance of Adminer\Plugins from adminer_object().

You can also switch to plugin autoloading: https://www.adminer.org/plugins/#use.

Sorry its still not working. I get

Fatal error: Uncaught Error: Class "AdminerLoginServersEnhanced" not found in E:\Bearsampp-development\sandbox\apps\adminer\adminer5.2.1\index.php:15 Stack trace: #0 E:\Bearsampp-development\sandbox\apps\adminer\adminer5.2.1\adminer.php(1151): adminer_object() #1 E:\Bearsampp-development\sandbox\apps\adminer\adminer5.2.1\index.php(33): include('E:\\Bearsampp-de...') #2 {main} thrown in E:\Bearsampp-development\sandbox\apps\adminer\adminer5.2.1\index.php on line 15

When I try to run it.

You need to require the class definition.

A better solution is to study https://www.adminer.org/plugins/#use and use that.
