 Just for the record, we are talking v2 (v2.2.0 to be more precise) to
v4 upgrade and not from a v3 one. Yes, only the Python bindings use v2
in the archive, but supports v4 as well (see compatibility[1]).
I don't know the compatibility level of the C/C++ API between v2 and
v4, but open to discussion if the former should be removed. At least
no other package uses it.
Do you know if upstream supports v2 (important and security fixes) or not?

Hi,

do we realy need a libzmq.so.3 in Jessie? Upstream is preparing a new
stable version now with libzmq.so.4. Given that the breakage between 3
and 4 is minimal (easy to port your software, most just works) do we
need to maintain 2 versions of zeromq?

Bug#743508: libzmq3: upgrading from 3.2.3 to 4.0.4 breaks python-pytango

2014-04-03 Thread Carlos Pascual 
Package: libzmq3
Version: 4.0.4+dfsg-2
Severity: normal

Dear Maintainer,

After upgrading libzmq3 to 4.0.4+dfsg-2, the following stops working:

~$ python
>>> import PyTango
>>> dev_name = 'sys/database/2'  
>>> dev = PyTango.DeviceProxy(dev_name)
>>> cb = PyTango.utils.EventCallBack()
>>> id = dev.subscribe_event("state", PyTango.EventType.CHANGE_EVENT, 
cb, [], True)

(waits forever... till  I press CTRL+C)

However, if I downgrade to libzmq3 3.2.3, I can repeat the previous 
python lines and the last one returns  immediately without problems as 
expected.
