After five cycles as PTL of Horizon, I've decided not to run for the
Newton cycle.

I am exceptionally proud of the things we've accomplished over this
time. I'm amazed by how much our project's community has grown and
evolved.

Looking at the community now, I believe we have a tremendous group of
contributors for moving forward. There are several people capable of
becoming great PTLs and overall the community will be healthier with
some turnover in the PTL role. I feel honored to have had your trust
over this time and lucky to have worked with such great people.

I will still be around and will help the next PTL make a smooth
transition where requested.
