I haven't gotten to play with it yet, since I'm still downloading it. I plan on doing a snapshot and upgrading my OpenBSD Parallels VM tomorrow.
Highlights:
- Now supports SMP on most Sparc64 platforms
- Loads of device driver improvements (and additions) for most architectures
- Built-in SNMP Support (no more need for net-snmp)
- Disks/Partitions/Filesystems larger than 2TB are supported for ffs
- Scads of little bugfixes
