Hello.

Thanks for the point of view.

Nice for parameters, did not see this new features. It looks pretty cool.
And should solve my purpose. Unfortunately, I did not expected to make an
upgrade for my clients, but this is an another "problem".

For NiFi registry, this is what I do when possible.
In the current case, this is not possible because the development cycle is
the following :
* Develop on my laptop.
* Validate the process on my instance.
* Then go to the client, and give him the process. The client do the
installation and I do not have right to install by myself.
* Moreover, all three instances and separated. Dev instance can not
communicate with Integration and Production. We could not have a registry
accessible by those three, and neither frmo my laptop.

For versioning, I understand. For the 1.9.3, it was just "a hope", but I
understand this is just bug fixing release, if there is one. I am OK with
that.

And finally yo give the "answer". You do not anticipate such a feature. So
no need to spend time on such things, because you are not favorable for
that. It's OK and if I really need, I can always do my own service, that's
the power of open source ;)

Thanks for all.

Etienne
