As the topic says, where can I get them?
Based on my review from Wikipedia it is wiser to install the LTS versions because they are supported for years.
At this writing I only find this in https://bitnami.com/stack/mediawiki/installer#linux
* Bitnami MediaWiki 1.28.2 - bitnami-mediawiki-1.28.2-0-linux-x64-installer.run - the current stable version) but I would like to get
* Bitnami MediaWiki 1.27.3 - bitnami-mediawiki-1.27.3-0-linux-x64-installer.run - the current Legacy version) - where can I get it?
