VirtualBox 5.0.0 Beta 1
更新細節：
# Features were added:
- Drag’n drop support (bidirectional) for Windows, Linux and Solaris guests
- GUI: Support hotplugging for SATA disks
- New, modular audio architecture for providing a better abstraction of the host audio backends
# Following items were fixed and/or added:
- VMM: improved timing on Solaris hosts with older VT-x hosts without preemption timers
- VBoxManage: when exporting an appliance, support the suppression of MAC addresses, which means they will be always recreated on import, avoiding duplicate MAC addresses for VMs which are imported several times
- API: block the removal of the current snapshot if it has child snapshots (only relevant for VMs without snapshottable hard disks, their presence always prevented removal), which resulted in VM config corruption
- API: mark VM configs with snapshots but without current snapshot as inaccessible, as this combination is nonsense
- API: fix information for some automatically generated events (only with XPCOM, Windows host was not affected), which caused errors when getting some of the attributes over the webservice
- API: fix crashes in Java API clients using the XPCOM binding, happened with output parameters only
- API: a number of settings (e.g. network settings) can now also be changed when the VM is in saved state
