Fun fact, today is the 9 year anniversary of the Libreboot project.
The very first Libreboot release was version 20131212, release on 12 December 2013.
However, this canon exists retroactively; the project was nameless until early 2014 when the name Libreboot was coined.
The first release, retroactively named Libreboot 20131212, was released on 12 December 2013, 9 years ago today.
I don't have a precise date for when the name Libreboot was coined, but it was February 2014 by my reckoning.
