What's Changed

Breaking Changes

• Iceberg on Google: a Google identity for REST catalogs, a per-source storage identity with a GCS reader, and one codec for every surface by @aaj3f in #2196

Bug Fixes

• Graph sources: a crawl keeps its ORDER BY, and a fused scan stays above an OPTIONAL by @aaj3f in #2199
