OLake Go (v0.11.0)

Sept 11, 2026 – Sept 26, 2026

🎯 What's New

Catalogs

1. Snowflake Horizon Catalog support -
   Added support for Snowflake Horizon Catalog as an Iceberg REST Catalog, with authentication options for Programmatic Access Token (PAT), Key Pair Authentication, and External OAuth. See Horizon Catalog setup for detailed configuration options.

Destinations

1. Iceberg v3 deletion vector support -
   Added support for Iceberg v3 deletion vectors as a delete mode, alongside the existing equality and positional delete modes. See Upsert Ingestion Mode for delete format options and their respective behaviors.

Platform Features

1. Improved telemetry and error classification -
   Added source_type to completed sync telemetry and improved error classification for configuration and CDC validation failures, providing more useful context when diagnosing failed runs.

🔧 Bug Fixes & Stability

1. Fixed case-sensitive PostgreSQL publication validation -
   Fixed PostgreSQL CDC publication validation to correctly handle case-sensitive schema and table names.

2. Updated MinIO image sources -
   Updated MinIO and mc image references to use the OLake-maintained mirror, ensuring Iceberg local-test and MinIO-based example stacks continue to work.

3. Fixed local Iceberg and S3 test stack management -
   Updated the local test Compose setup so the destination stack manages its own MinIO instance, preventing S3 teardown from unintentionally removing Iceberg services and cached data.
