In the distant past* @LWN used to do a yearly Linux and free software timeline. As a sometime contributor and reader, I enjoyed those timelines as a way to look back on the past year -- and as a reference to when this or that happened.
This year, I thought, why not bring it back and see if people enjoy it and find it useful?
* (or not-so-distant, depending on your perspective and how many decades you have under your belt...)
