I just found a bug in new UPX 3.92.
When I compressed the library MFC120.DLL (regardless of used compression level or executable version dos/win32) the result was that application which use this library failed to load with initialization error 0xc0000005. If the library is decomressed and repacked by previous UPX 3.91 (regardless of used compression level or executable version dos/win32) it always works fine.
So be carefull and keep the old version handy!

UPDATE: and it's not the only one, IDRVDLL.DLL, Idrvdll32e.dll from intel BIOS tools also gets crippled so the bug may affect much more Win32 PE files!
