Change Log contract to LoggerInterface.

[LEI]

After updating to Laravel 5.6, this message is displayed on error (e.g. wrong column name):

Class Illuminate\Contracts\Logging\Log does not exist

As described in the upgrade guide, Illuminate\Contracts\Logging\Log should be changed to Psr\Log\LoggerInterface.

Is this backward compatible with lower version of Laravel? We may have to do a major bump if not. Haven't updated to 5.6 yet and I can't verify this yet. Thanks!

Maybe we should just use the facade and remove the interface. Or resolve it using IoC app('log') key?

Not tested, but the upgrade note seems to indicate there is no side effects:

This interface has been removed since this interface was a total duplication of the Psr\Log\LoggerInterface

The Psr namespace should be available before 5.6 as well, I'll try to find since when exactly.

The interface signature hasn't been modified since its introduction on 5.0, except for a PSR-2 style change. Though both useFiles and useDailyFiles methods are missing from the PSR-3 interface introduced in 5.6.

I can't find a note about it in the documentation. I tend to think it should be backward compatible with the DataTables usage of the logger.

Confirmed still working on 5.5, thanks!
