I think it would be good practice to roll out fixes to support earlier versions of oxwall software like major software developers. I say major because I consider oxwall to be a major player, because of the nature of the software designed and its purpose.
The reason Oxwall CMS should not be considered a normal 3rd party application software where developers can say this issue will be fixed in the next update, is that it is a platform and it is its own operating system for any website.
Vendors build complex systems of business around the platform just like they would with an institution running Windows Xp and cannot just instantaneously upgrade to new versions of platforms every time an update is released. It's the same as running a business, upgrades need to be planned and change-managed.
If a business purchased propriety software that only works under a certain installation of Ms Windows and this is crucial for business operations. You have no choice but to stick with this until development of the application has reached to the same level as its parent operating system or until the change team can explore a suitable alternative.
This is the same with oxwall, you invest in systems that are specific to the nature of your business and crucial to its operation and cannot afford to change over until proper assessments are carried out and research and documentation has been prepared. Many sites also rely on development from 3rd parties and cannot depend on 3rd parties for parallel and synchronous support of their plugins.
Oxwall is becoming a major player and growing. It will become the choice of any business/company/organization in the future, even when pitted against industry leaders like social engine.
As an open source alternative, Oxwall is providing continuous development to the point where it is developing its mobile plugin and providing it to the community free of charge. You need to pay for this from other developers in the vicinity of a few hundred USD more.
Oxwall developers care about its community and it is much appreciated by its users.
I'm sure I speak on behalf of the community when I say Oxwall software is enriching lives and fostering communities and sometime in the near future you will see its application in systems that reach such a a large scale global audience, and used for such a force of good. E.g. Communities established to help poverty and disaster stricken victims. Developers and site owners will endorse the software in such a a way that your team may be under serious stress to keep up with demand.
It is for these reasons, that I stress that each Oxwall platform version released needs to be continuously supported for a reasonable period of time, as site features, plugins and user interaction with the site will be compromised by forcing site developers to update an entire operating system to fix inherent bugs.
