Self intersecting shorelines were not exported correctly in shapefile/AT5 format. If you had an issue whereby you couldn't see your shoreline polygon at all after a shapefile export, this fix may well resolve it.
Tide times outside of a track range were not applied to the interpolation of water level offsets in the track. This has been fixed so it is now possible, for example, to create a tide station with a single water-level data-point per month and use that for lake level offsetting.
