All talks are available for watching on YouTube.
We also had two hands-on workshops:

Main topics:

Issues
No major issues were reported; the venue provided a professional environment with comfortable spaces for talks, networking, and catering.
The only issue we had (which was also reported last year) was that the support screens intended to help attendees in the back see the slides were positioned too low. We tried to mitigate this, but due to a misunderstanding with the audio/video service providers, they remained difficult to view properly.
Feedback
About 20% of attendees gave feedback (less than last year) and we are glad the results were very good. In addition, all the talks were appreciated, getting high rates.
See you next time!
