VirtualBox 4.2.16 (released 2013-07-04)

업그레이드 발표 후 종종 짧은 시간 만에 새로운 버전을 발표하곤 하는 VirtualBox이다.
무언가 긴급한 에러 수정이 필요한 상황이 그 이유일 것이다.

This is a maintenance release. The following items were fixed and/or added:

• OVF/OVA: don't crash on import if no manifest is used (4.2.14 regression; bug #11895)
• GUI: do not restore the current snapshot if we power-off after a Guru Mediation
• Storage: fixed a crash when hotplugging an empty DVD drive to the VM
• Storage: fixed a crash when a guest read from a DVD drive attached to the SATA controller under certain circumstances
• EFI: don't fail with 64-bit guests on 32-bit hosts (bug #11456)
• Autostart: fixed VM startup on OS X
• Windows hosts: native Windows 8 controls
• Windows hosts: restore native style on Vista 32
• Windows hosts / guests: Windows 8.1 adaptions (bug #11899)
• Mac OS X hosts: after removing VirtualBox with VirtualBox_Uninstall.tool, remove it from the pkgutil --pkgs list as well

뭐 무조건 새로운 버전으로 설치, 활용하자.
