> I am not able to follow, `xEx{2}` renders the associated `Throwable` and
produces max. `2` lines – this is identical to the behavior that was in
`<=2.23.1`. An important difference is that, in #3073, we switched prefixing
the rendered stack trace from white space to newline.
The documentation says:
> Outputs the first `depth` lines of the stack trace
Reading this I would expect to see the first `depth` stack trace elements.
This interpretation is confirmed by the documentation of `short`:
> Outputs the first line of the stack trace (analogous to `%ex{1}`)
When I use `short` I get the exception message + the first stack trace
element. So `short` currently works like `%ex{2}`.
I have never trimmed stack traces, so I don't know what users expect, but
personally I find the numbering not intuitive. Also `%ex{1}` and `%ex{2}` means
that no information about the causality chain will be printed, so the setting
is useless for debugging.
