Undid revision 1035689294 by Tonystewart14 (talk) Restoring IP revert, will make additional improvements
One page just for one short table?! NOOO, it is harmful for editors, readers, and WP || merged to its main article at OpenBSD#Releases, same as OpenSUSE version history which was created by me on 30 October 2016‎ but two days ago I merged it to its main article without any request -- see also NetBSD#Releases

Open-source software has since been replaced by one-button computers, one-channel televisions, and closed-source software which, after you purchase it, becomes obsolete before you have a chance to use it. People subsist on [[soylent green]]. The theme song is performed in the [[reggae rock]] style of [[The Police]].
