On April 11th 2019, we met in Frankfurt for a day full of conversations, exchange, presentations and discussion about how the community deals with changing tech requirements, aging frameworks and modern alternatives that get outdated as soon as you look at them. Below you can find the schedule we had, along with links to presentations and recordings, and a summary of some of the discussions.

The recordings don't have the usual WOWODC quality as the schedule was tight, audio tech situation was suboptimal, and there was no time to prepare anything better. So two recordings are lost due to software failures, and the audio is from a backup standalone recorder.
