VirtualBox 5.0.24

VirtualBox 5.0.24 (released 2016-06-28)

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

• VMM: reverted to the old I/O-APIC code for now to fix certain regressions with 5.0.22 (bug #15529). This means that the networking performance with certain guests will drop to the 5.0.20 level (bug #15295). One workaround is to disable GRO for Linux guests.
• Main: when taking a screenshot, don't save garbage for blanked screens
• NAT: correctly parse resolv.conf file with multiple separators (5.0.22 regression)
• Storage: fixed a possible corruption of stream optimized VMDK images from VMware when opened in read/write mode for the first time
• Audio: imlemented dynamic re-attaching of input/output devices on Mac OS X hosts
• ACPI: notify the guest when the battery / AC state changes instead of relying on guest polling
• Linux hosts: fixed VERR_VMM_SET_JMP_ABORTED_RESUME Guru Meditations on hosts with Linux 4.6 or later (bug #15439)
• Solaris hosts: make the GUI work on Solaris 10 again (bug #15549)

VirtualBox 5.0.22 (released 2016-06-16)

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

• VMM: fixes for certain Intel Atom hosts (bug #14915)
• VMM: properly restore the complete FPU state for 32-bit guests on 64-bit hosts on Intel Sandy Bridge and Ivy Bridge CPUs

• Main: properly display an error message if the VRDE server cannot be enabled at runtime, for example because another service is using the same port
• NAT: Initialize guest address guess for wildcard port-forwarding rules with default guest address (bug #15412)
