[zeromq-dev] Moving to 0MQ/3.0, yes or no?

[Gregg Irwin]

What is the migration model for 0MQ apps? If users can continue to use
the 2.x branch, use 3.x side-by-side, and still get critical fixes for
2.x, how painful will breaking changes be in 3.x?

I'm too new to 0MQ to offer any useful advice on specific changes,
but, for me, knowing what changes are coming, giving me the option
of moving forward or sticking with what works, and cleaning house are
all important. I don't expect things to be perfect in early designs,
and learning from the past will make things better in the future. I
greatly value stability, but gladly accept change if it's not
arbitrary.
