I have a policy that is to support at most three releases back. Requiring upgrades to support new software is normal. New APIs are released, new features that allow for simpler code or remove unneeded unsafe blocks. These are good things. People don’t need to install the latest software. If they want to install the latest software, then they will need to install the dependencies that support that software. That can be operating system versions, compiler versions, or other library dependencies. I really don’t understand this mentality of wanting to update one piece of software, but also not wanting to update any other software it might depend on.
