the next release of the Terrascope backend will contain a fix to interpret date intervals as half open as opposed to closed. This fix aligns the backend with the specification.
As a result, the last date of the interval will no longer be included in the result.
We expect little impact for most users, but in some cases users may thus get one less observation.
The simple migration is to simply update the end date to the next day.
Please let us know if this would present a specific issue.
