How far back should we consider when estimating the impact of a change like this? I was looking at current stable versions to estimate the impact of the change. Lots of users avoid the bleeding edge distribution releases, but most update to track the current stable/LTS releases. Or they won't complain that it's unfair for org to expect them to update emacs to the current stable/LTS version. Ubuntu, Red Hat, CentOS and SuSE are 25.1 or above for their most recent long term support releases. Some of these distributions go a lot further with various forms of long term support. I think Red Hat goes back 8 years for example, and that emacs is really old. It looks like 25.1 is available, but not yet the default for Debian "stretch" (Debian 9.13), which is the "oldstable" for Debian. With Debian backport efforts I don't know if this means months or years. The web page for Emacs25inStretch has not changed since 2017, so it might never happen. -- Robert Horn rjhorn@alum.mit.edu
