maybe great new 2.16 is also worth to be mentoined in history
https://piwik.org/history/
e.g.

• because of LTS or
• because of being able to track time on all pages visited (because of good working heartbeat, which is not possible with many other tracking tools)

btw: maybe ito would be good to inverse order of history to show latest one first:
otherwise as a visitor one get first the feeling that one is on an old not well maintained page...
