There was no keynote, so I went directly the session High Performance via Psychological Safety by Joshua Kerievsky y Heidi Helfland. Nice session, I got several resources to investigate.
A session that I really enjoyed was Writing better BDD scenarios which was facilitated by Seb Rose (cucumber) and Gaspar Nagy (specfow). The session was workshop type, the content was very useful and the dynamic of the session was very appropriated.
At the end of the day there was a session called «Agile tonight!» that was like a TV show with interviews, moderated by Paul Hammond. I just visited this session for a while because it did not catch my attention. So I moved to a common area to share «mate» drinks with some colleagues.
