I had taken a poll a while back and the consensus was that dCore made from Ubuntu releases should focus on the LTS and not include the 6 month interim releases. While I have included the 6 month ones since then to provide the latest release and it's packages, that is not very productive when there are Virtualbox and other kernel modules to be made for that release, startup scripts specific to package versions, etc, just for that Ubuntu repo to be unavailable in a few months.
So I am going to create new dCore ports from the LTS Ubuntu and Debian releases for future dCore ports. I want to focus on quality more than quantity. The existing Debian/Ubuntu dCores will still be available for download and access to thier respective repos. Though Debian Wheezy has reached it's LTS end of life on May 2018, I have said I would keep dCore-wheezy up as long as it's repo is accessible. Older dCore ports can be useful for old hardware and will be available for the forseeable future.
That being said, x86 will be supported as long as it can be. Debian, no problem. Ubuntu has not had an LTS x86 installer as of Xenial, but I have both an x86 Bionic and (non-LTS) Cosmic installed to hard drive. Just depends on Ubuntu in the future in regards to their x86 repo.
