plugin migration

[domlat]

Hi, I am migrating our custom plugins from 4.8 to 5.3. I found that although I could simply put (for example) enum-option.php in the adminer-plugins directory, for my own plugin it has to be listed in adminer-plugins.php. This is not clear in the documentation as far as I can see and nor it is entirely clear why.
Also worth mentioning somewhere that driver_config() is no longer available. I have replaced it with
$driver = Adminer\driver();
$this->functions = $driver->functions;
$this->grouping = $driver->grouping;

Okay, got there, the plugin classname needs to begin "Adminer".
