This issue marks the final hardcopy version of the IETF Journal. Since 2005, the Journal has been printed three times a year, and distributed at IETF meetings and by postal mail.

The IETF returned to the beautiful European city of Prague for its 99th meeting. It was a busy meeting with lots of interesting work; we share here only a snapshot of the events and discussions that made this meeting so memorable.

In this issue, you’ll learn about implementation work taking place in the Human Rights Protocol Considerations Research Group, the latest security updates to Network Time Protocol, new email-related Working Groups JMAP and EXTRA, as well as the important coding work that took place as part of the IETF Hackathon.

Our regular columns from the IETF, IAB, and IRTF chairs and coverage of the Birds-of-a-Feather meetings and presentations from the Applied Networking Research Prize winners wrap up the issue.

We are hugely grateful to all of our contributors. Please send comments and suggestions for contributions to [email protected] or tweet us @ietfjournal.
