which have been approved by the Board.
Please Note
The Board typically approves the minutes of the previous meeting at the
beginning of every Board meeting; therefore, the list below does not
normally contain details from the minutes of the most recent Board meeting.
ASF Members may have access to a

Report was filed, but display is awaiting the approval of the Board minutes.
Hamilton is a lightweight in-process framework to define, execute, and
observe directed acyclic graphs (DAGs) that express data transformations. In
Hamilton, one can express complex DAGs of transformations, e.g. from
dataframe transformations (using pandas, polars, PySpark), machine learning
pipelines, through to regular software engineering API request and LLM API
based workflows. Observability hooks are built into the framework. The
Hamilton UI is a self-hostable service to capture observability output from
workflow runs.
Hamilton has been incubating since 2025-04-12.
### Three most important unfinished issues to address before graduating:
1. Finally publish a release
2. Publish releases of all other components
3.
### Are there any issues that the IPMC or ASF Board need to be aware of?
