+## [5.0.2]
+### Added
+- A validation check for `INSAR_ISCE_BURST` that will fail if a granule crosses the antimeridian.
+
 ## [5.0.1]
 ### Fixed
 - Upgrade the `openapi-core`, `openapi-spec-validator`, and `jsonschema` packages to their latest versions. This is now possible thanks to the pre-release of [openapi-core v0.19.0a1](https://github.com/python-openapi/openapi-core/releases/tag/0.19.0a1), which fixes <https://github.com/python-openapi/openapi-core/issues/662>. Resolves <https://github.com/ASFHyP3/hyp3/issues/1193>.
