We (the AlacrityVM team) are pleased to announce the availability of the
v0.2 release. There are numerous tweaks, fixes, and features that we
have added since the v0.1 days. Here are a few of the key highlights.

*) VENET support:
*) zero-copy transmits (guest memory is paged directly to the
physical adapter on the host, where applicable)
*) "SAR offloading" (essentially bi-directional GSO with "64k MTU")
*) pre-mapped descriptors to reduce latency
*) pre-loading of mmu context to reduce latency

*) shm-signal's are now routable (e.g. future MQ support)

*) vbus is optionally managed in its entirely from the rebundled qemu
*) "-net venet-tap" will fully initialize the interface
internally..no more scripting!

*) vbus components are automatically reaped when the guest exits, even
if the exit is not clean.

We will update the performance numbers ASAP and announce any changes.
