Why requires zmq < 1.3.0 ?

[litlighilit]

Long before, nim's zmq has upgraded over 1.3.0
For some reasons, I manually install the newer version of nim-zmq,
then during my using jupyter, I havn't found any errors which occured.
Therefore, I just wander what caused the version needs "less than 1.3.0" ('< 1.3.0')

I believe there were some API changes when zmq wen't from 0.4 to 1.0 which caused compilation to fail, then jupyternim was updated to work with 1.0 but a limitation on the version was kept. It doesn't look like 1.3.1 is very different though, so this limit could probably be relaxed. I'll have a look in the next version, probably after Christmas.

Here I'd like to give more details to offer a little references: (in the case that I may not be able to spare time later)
To begin with, I compiled in Windows.
where I download all required nim package source, then compiled them, respectively and in depending order.

Later I realized it's better to build instead of install if only the binary file is needed.
Therefore when I need to compile it in another Windows mechine, I compiled it using command line with option --path: to give dependency search path, still with the privious downloaded source.
And this time it's successfully compiled as well, and it worked.
