netbsd-7 branch support will end tomorrow

Usually branches from only last two releases are supported by the project, with one month grace period for the branches from two releases back. Thus, netbsd-7 support was supposed to end in the middle of March. Nevertheless, due to pandemic the project decided to extend netbsd-7 support up to 30th of June. Because of this, netbsd-7, netbsd-7-1 and netbsd-7-0 maintenance will be stopped starting 1st of July, 2020. Definitely, the project team encourages to update to the latest release and promises to release NetBSD 9.1 soon.
