Just a few screenies:

[jansule]

Thanks for the feedback. I applied your suggestions and added a list of the related releases that we will publish throughout the day.

Is there anything else that should be changed?

Looks good @jansule - thanks! Could you add a mention to @compassinformatics as they paid for some of my time attending the sprint?

[jansule]

Bad timing @geographika :grinning: But sure, I can add this
