To "port" is to bring things over from elsewhere. They will become either new pages or major updates. Small pages and minor updates are not noted.

I am continuing to adjust article dates to my earliest references from this previous content management system. Many items are from yet an earlier and whose true changelogs will not be ported. It saddens me that I am losing much of the changelog concept, since I have explicitly disabled it in WordPress, although I do bury archives in The Internet Archive Wayback Machine.
