Hi Donovan,
* Will APIMan form some part of the new 3Scale integration
As per our blog posts in the past, the aim is to integrate the apiman gateway with the 3scale manager in the community.
In the next release I'll hopefully be providing some initial integration for folk to play with, but I'm not in a position to comment yet on fuller integration with the UI, etc -- rest assured as soon as I can, I'll let you all know.
Of course, I will forward your interest to the relevant parties (and that of others who contact me -- or have already done so).
(more specifically, the on premise solution/OpenShift)?
I can't really speak about products, but I will put you in touch with people who can!
If not, why the 1.3.0 release (since this adds new features)?
Some of this work is setting the ground for future work (including the above), ensuring that we keep the apiman community well-served in terms of gateway bug-fixes, features, performance, etc.
The reason for the version number bump is (in part) that some small incompatible changes were introduced -- so, according to semver that requires a minor increment rather than patch. Plus some substantial new features released (apiman Vert.x gateway, headless registry, etc).
Regards,
Marc
