Hello,
I have a feedback for the BetaArchive wiki which is powered by MediaWiki to be upgraded to newer version 1.27.1. The reason why is it's good to be update and the version at it uses is version 1.26.2, which MediaWiki version 1.26 is an legacy released which the support in security will end at the year of 2016. Therefore, I recommend the wiki on BetaArchive to be upgraded as it's support is LTS (Long Term Support) which support for MediaWiki 1.27 will at the end of the year 2019. If the owner/administrator who manages this site is reading this, please make the decision to update as soon as possible.
Sincerely,
Bob Pony
