The DBAppender is missing from logback-classic-1.2.10 given by spring-boot 2.5.9

It (and other db related classes) seems to have been removed by this commit

https://github.com/qos-ch/logback/commit/87291079a1de9369ac67e20dc70a8fdc7cc4359c

I can't see any mentioning of this being removed in the news or in the online documentation.

This is a crucial functionality within banking where customer data is not allowed to just be thrown into text file logs at will or random. You as Swiss should be quite familiar with this.

So my report is simple: where did the db classes go?
I would assume they have been placed in some external package.
