It's a sunny cool Sunday morning at Perth airport. I'm trying to make a MediaWiki extension work for MediaWiki 1.31. I got thinking about it because of the recent email about 1.32 being EOL (while 1.31 is LTS and will be around till June 2021). I usually try to support all current versions, even LTS ones. Mostly it's easy enough to do, although I also combine it with only supporting active versions of PHP, so I get to ignore some of the things that only apply to PHP 5.6 (which ended a year ago).
