the midas wiki was updated to the latest LTS point release 1.27.5.
Also, an installation error was fixed that prevented confirmation of new accounts (git checkout
REL1_28 instead of REL1_27, resulting in a version mismatch).
Support for MediaWiki LTS release 1.27 ends this Summer.
Next LTS release series is 1.31, see https://en.wikipedia.org/wiki/MediaWiki_version_history
This version requires php version 7 or newer which comes standard with ubuntu LTS 18.04
and el8 (RHEL8), but not with el6 (SL6) and el7 (CentOS-7).
I guess we shall start planning this upgrade and the move of the wiki to a new host machine.
