Oracle VirtualBox 4.3.4 has been released. The downloads and changelog are in the usual places. I thought 4.3.4 included a fix for the Mac OS X upgrade issue I posted about, but it didn’t. The install of 4.3.4 was seamless and didn’t require any fiddling about. 🙂
I’m currently running VirtualBox 4.3.4 on Fedora 19, Oracle Linux 6, OS X Mavericks and Windows 7.
