Schema Release Notes

Definition change for the coordinate fields of the Rearrangement and Alignment schema. Coordinates are now defined as 1-based closed intervals, instead of 0-based half-open intervals (as previously defined in v1.1 of the schema).

Reference Library Release Notes

Several changes to the python and R reference library to support the new schema coordinate definition and improve validation. See the package release notes for details:
