Brenda,
I want to add to this, the fact that you add a link to where the
change was discussed or made is even more helpful. I was having
problems finding where an item on Mark's #changelog list was at in
the group.
In each thread-starter I've included a link back to Mark's posting in beta@ so that interested people can easily go see what else he said.
I've not attempted to track down any further discussion within beta@ of the particular items. I'm going to leave that as an exercise for you, dear readers, else I might not ever complete one of these postings.
Anyone interested in a volunteer research-assistant job could take on the task of citing and summarizing any further discussion there may be on particular items. Of particular interest might be if Mark expressed a motivation for choosing one suggested implementation versus another.
