Every six months (around May 1 and Nov 1) OpenBSD makes an official software release.
To accompany this free software released on the internet, we make
artwork and a song
which are distributed along with the software on a set of CDs. The
sale of these items retains the OpenBSD Project leader (Theo de Raadt)
to herd developers full-time towards a software release every 6 months,
as well as paying other project costs.
Our primary distributor Zednax runs the OpenBSD Store and sells our releases worldwide out of the UK.
