It's not actively developed anymore. You can of course hire us to add 
the functionality of your choice.

I would certainly go with 2.0.

All 1.0 functionality have been moved to 2.0. One exception is central 
repository of endpoints (zmq_server) which have been ditched in version 
2.0 in favour of established location services such as DNS. Queue limits 
functionality (ZMQ_HWM,ZMQ_LWM) and on-disk offload (ZMQ_SWAP) features 
haven't been ported to 2.0 yet but they are being worked on and will be 
available soon.

Mostly depends on funding and community participation in the process. 
However, this is an open source project, so you have the thing available 
even before we decide to mark it as "stable". If it's stable enough for 
you, just use it.
