12 Change log
This section summarizes the changes between VirtualBox versions. Note that this
change log is not exhaustive; not all changes are listed.
VirtualBox version numbers consist of three numbers separated by dots where the
first number represents the major version, the 2nd number the minor version and the
3rd one the build number. Build numbers of official releases are always even. An odd
build number represents an internal development or test build.

• Guest SMP with up to 32 virtual CPUs (VT-x and AMD-V only; see chapter
3.7.2.2 , “Processor” tab , page 48 )
• Windows guests: ability to use Direct3D 8/9 applications / games (experimental;
