Hi, Community support is always an interesting question as there is no support contract to define what "support" means ;) IMO, the community does at least support the latest release. Then if some community members can work on supporting older ones, that's good, but IMO it doesn't have to be the priority of the community to support older versions if it slows down main development. Long term support is something expensive to provide, and that some companies can bill for; unless the companies that bill for older version support do invest back with contributors in the project to provide such support in the community channels, then it's just so much simpler and more fair to say that community only supports latest release and drop all older ones, and let people who can make money with it take care of older support from people who are ready to pay for it.
Cheers
