ChangeLog/5.0
System emulation
Incompatible changes
- The bluetooth code has been removed without replacement. It was quite neglected over the years and likely not usable anymore. You can passthrough a dedicated USB bluetooth dongle to guests on most machines instead if you still need bluetooth in your guest.
- The -virtfs_synth option has been removed. You can use -fsdev synth together with -device virtio-9p-... instead.
