[zeromq-dev] czmq

[Pieter Hintjens]

The v3 API is definitely nicer and simpler than what we had before,
particularly for serious server construction.

I think what we have is solid and unlikely to change much. We'll be
adding more classes, perhaps deprecating one or two of the ones that
are there now. I'm not sure the zdir and zdir_patch classes are
useful, for example.

The shift is probably large enough in the core areas -- sockets and
actors -- that I'd make a new binding focusing on the classes I found
useful in my language. That'll be zauth, zbeacon, zcertstore and
zcert, zpoller, zgossip, and a few more.
