+Today, Overture released a patch for the September data. The new release paths are:
+
+#### Amazon S3
+```
+s3://overturemaps-us-west-2/release/2026-09-23.1
+```
+
+#### Microsoft Azure
+```
+wasbs://release@overturemapswestus2.blob.core.windows.net/2026-09-23.1
+```
+
+Shortly after this release went public, we found a bug in the new GERS ID generation for base and building_parts features. This patch fixes the issue by fixing the UUIDs assigned to the base and building_parts for this release.
