 ## [Unreleased]
 
+### Changed
+- **BREAKING**: `pw.io.iceberg.write` to a Glue catalog no longer accepts `DateTimeUtc` columns. Glue's metastore has no timezone-aware timestamp type, so previous versions silently dropped the timezone on read-back; writes now fail with an explicit error instead of corrupting the zone. To store UTC timestamps in Glue, convert to `DateTimeNaive` with UTC-normalized values, or write through the REST catalog, which preserves the timezone.
