Oct 02, 2015  Oracle has released VirtualBox 5.0 Maintenance Release 6. This release is a major improvement which include a large number of changes and bug fixes; between the others I would like to mention big improvements we did on Microsoft Windows 10 RTM (Release 10240) platform ( as guest and host platform.

1. Virtual DJ Software, MP3 and Video mix software. VirtualDJ provides instant BPM beat matching, synchronized sampler, scratch, automatic seamless loops and remixing functions, effects, and much more.
2. Oracle VM VirtualBox Extension Pack. Free for personal, educational or evaluation use under the terms of the VirtualBox Personal Use and Evaluation License on Windows, Mac OS X, Linux and Solaris x-86 platforms.

• Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for VirtualBox.
• Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.

VirtualBox 6.1.0 RC1 changelog:

• list of changes introduced in Beta 1 can be found here.
• list of changes introduced in Beta 2 can be found here.

VirtualBox 3.0.0 Change Log

This version is a major update. The following major new features were added:

• Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only; see chapter 3.7.2.2 of the user manual)
• Windows guests: ability to use Direct3D 8/9 applications / games (experimental; see chapter 4.8 of the user manual)
• Support for OpenGL 2.0 for Windows, Linux and Solaris guests

In addition, the following items were fixed and/or added:

• Solaris hosts: allow suspend/resume on the host when a VM is running (bug #3826)
• Solaris hosts: loosen the restriction for contiguous physical memory under certain conditions
• Mac OS X hosts: fixed guest PAE
• Linux hosts: kernel module compile fixes for 2.6.31 (bug #4264)
• VMM: fixed occasional guru meditation when loading a saved state (VT-x only)
• VMM: eliminated IO-APIC overhead with 32 bits guests (VT-x only, some Intel CPUs don’t support this feature (most do); bug #638)
• VMM: fixed 64 bits CentOS guest hangs during early boot (AMD-V only; bug #3927)
• VMM: performance improvements for certain PAE guests (e.g. Linux 2.6.29+ kernels)
