Re: How long are old pkgsrc releases supported?

[Greg Troxel <gdt%lexort.com@localhost>]

pkgsrc releases are supported until the next branch is cut.

As for old bits, usually they are around for a while, but TNF does not
have infinite disk space.

In this case, I would expect you have a staging/test/etc sever with the
same OS and similar hardware, and that you could check out pkgsrc-2018Q2
from cvs and build the binary package you need.   It is ok to mix
prebuilt and home-built packages as long as the OS branch and pkgsrc
branch (and mk.conf options) match.
