Sam Hartman has announced that he will not run for a second term as Debian
Project Leader at this time. “TL;DR: Overall, being DPL has been
incredibly rewarding. I have enjoyed working with you all, and have
enjoyed the opportunity to contribute to the Debian Project. I hope to be
DPL again some year, but 2020 is the wrong year for me and for the project.
So I will not nominate myself this year, but hope to do so some future
year.“
