bruin-data/ingestr v1.0.66 was published on July 6, 2026, with a narrow OneLake fix: Fabric managed area directories are skipped during OneLake table path handling. For data engineering teams moving data into Microsoft Fabric, that matters because managed storage areas should not be treated like ordinary table paths by a loader or sync process.

ingestr v1.0.65 was published on July 6, 2026, with a small set of changes that matter most around Arrow casting, CDC metadata, and OneLake path behavior. The main data path fix is in the data buffer: Arrow array offsets are now honored when casting, which matters when a slice is passed through a load path instead of a full array. It is not marked as a prerelease.

SQLAlchemy had a small but useful week for data engineering code that builds SQL through Python instead of string templates. The recent work is mostly about clearer ORM errors, safer dialect rendering, and documentation that reduces bad assumptions in concurrent SQLite tests and jobs.

Polars py-1.42.1 was published on June 30, 2026, with a practical patch set for parquet scans, query correctness, and runtime failure cases. The most useful change for data engineers is sampled resolve mode for multi file parquet metadata, which targets one of the dull but expensive parts of reading many files.

pandas v3.0.4 was published on June 28, 2026 as a patch release for the 3.0.x line. For data engineers, the main item is a fix for DataFrame.to_sql() and read_sql_table() with ADBC engines, where table and schema names were not quoted as SQL identifiers. The GitHub metadata does not mark this as a prerelease.
