 **Crypto support** - dm-crypt was ported to DragonFly.  This means that it is now possible to encrypt DragonFly partitions (e.g., HAMMER and UFS). While it is possible to only encrypt certain partition like `/home/`, it is also possible to encrypt the whole root file system. The latter is especially useful for mobile devices. Further, some parts of the code are SMP aware, so expect a speedup if using multi core machines.
 
-**Packet Filter (pf)** - Pf was updated to a version based upon OpenBSD 4.2. The previous version of pf in DragonFly was based on OpenBSD 3.5. This, in addition to laying the ground for further following OpenBSD's implementation, introduced several performance gains: Information like route-to, altq, tags, etc are now stored in the `mbuf` header directly. This was partially already the case up to DragonFly 2.6, but now the implementation corresponds to OpenBSD's. Furthermore an often unnecessary checksumming was removed, which gains another 10% performance.  Also state tables and interface bound states where reimplemented and the pf_test_*() functions where fold into pf_test_rule() to make  things clearer. DragonFly-specific additions, support for fairq packet queueing and pickups, have remained intact.
