" Dear colleagues,

I'm glad to announce CARP support already commited to HEAD. The porting
job has been done by Max Laier, and I'm going to maintain CARP in the
nearest future, because I use it at my day job.

We will do our best to ship 5.4-RELEASE with CARP. Long time ago Max has
extended struct ifnet before RELENG_5 branching. With this far-seeing
change we can now MFC without ABI breakage. Patches for RELENG_5, that
are going to be commited soon are available here:

If you are interested in CARP, or if you are going to use it in near future,
then do not hesitate, download the patch and try it out!

Before asking any questions, pls consult man page. It is already in the patch.
If you still have questions, I'd be glad to help you.

Totus tuus, Glebius.

That message was 5 days ago, and the patch was updated today.
Gleb Smirnoff will be maintaining the CARP port and asks for reports, both positive and negative to be sent to
