Support maxdepth option on File Component when recursive option is enabled
Any idea of when this will be implemented - or might it be possible to have it already in 2.8.2?
Its not part of 2.8.2. We would normally try to only backport bug fixes to patch branches. But the 2.8.2 already have a number of non bug fixes backported so it could be possible we could do for this as well.
