If you're considering upgrading to 4.6 and recursively importing is important to you, you might want to hold off.
I recently wanted to import a whole lot of files and saw it presented the files when recursively import was ticked, but when i clicked on Import files , the interface said X files imported instantly and no files were imported.
I know there's a formal bug reporting framework, and I'm not posting this to somehow get the issue fixed, it appears to have been recognised earlier and now fixed in the nightly builds. (I built 4.6, and since built todays/yesterdays).
The purpose of this post isn't a dig at the developers, but to warn anyone who might be considering an upgrade. If i knew it was an issue, i'd have deferred upgrading. (Some time was spent fault finding as i was accessing files for the first time from a NAS)
I understand that there is likely going to be a 4.6.1 released about a month or two after 4.6, so it should be soon.
