Info on upgrading to v4
agendaEventMinHeight 3.6.0
Guarantees that events within the Agenda views will be a minimum height.
Integer / null
An integer pixel value can be specified to force all Agenda view events to be at least the given pixel height.
If not specified (the default), all events will have a height determined by their start and end times. This may result in visually scrunched events if an event’s end is very soon after its start.
