Here we list major project milestones.
== 1999 ==<!--T:2-->
{{Quote|Indeed it was <!--T:3-->* Nov 1999 when our engineers started adding bits : Alexander Tormasov visited Singapore and pieces of containers technology proposed a new direction to Linux kernel 2Sergey Beloussov: container virtualization.2. Well, not exactly "He formulated three main components: containers",but rather "virtual environments" at that time -- as it often happens a set of processes with new technologies, the terminology was different (the term "container" was coined by Sun only five years laternamespace isolation, file system to share code/ram and isolation in 2004).|Kir Kolyshkin|http://openvz.livejournal.com/49158resources.html}}
