Dask 2026.7.0 was published on July 6, 2026, with expression protocol work at the center of the release. For data engineers running Dask in dataframe ETL jobs, the main change is support for composite expressions through __dask_exprs__, plus a related fix that avoids graph materialization in is_dask_collection for expression wrappers. This release is not marked as a prerelease.

Dagster 1.13.12 was published on July 2, 2026, with fixes that matter most to automated orchestration, dbt event conversion, and code location recovery. The main operational change is a fix for partitioned asset checks that could halt an automation tick when the target asset was not materialized in the same tick. This core release is paired with library version 0.29.12 and is not marked as a prerelease.

ingestr v1.0.64 was published on July 2, 2026, with a focused Snowflake fix for multi table writes that could deadlock when the connection pool was exhausted. This is not marked as a prerelease, and the practical point is simple: concurrent Snowflake table writes should no longer stall on pool starvation in this release.

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.

Toil is a workflow engine for batch pipelines, with strong CWL and WDL support. This week’s activity is worth reading because it adds CWL loop execution, injects container resource accounting, and tightens restart coverage for WDL jobs that die on purpose.
