Apache Hop last week. 21 PRs. Apache Hop strengthens foundations with PyHop (Py4J for Python), Git-based project creation, key bug fixes, expanded variable support, and ongoing platform cleanup and modernization.

Your data integration platform likely has vulnerabilities, you just donโ€™t know which. Dependencies ship with #CVEs. At Putki (Powered by Apache Hop), we scan daily; latest release has no CVEs >9. @know.bi @hop.apache.org

Mar 13โ€“20 was huge for Apache Hop: 40 PRs merged, 50 issues closed, 10 contributors. Highlights: JavaScript back in Script transform, new editor, SSH tunnels, project versioning, metadata drag & drop, XML cleanup, Excel/Input fixes, Weblate translations. @hop.apache.org

Installing an open source data engineering platform like @hop.apache.org is easy, keeping it running in production for years is hard. We're building @putki-io.bsky.social to make running data engineering project in production and at scale easier for data teams. #apachehop #putki #dataengineering

The EUโ€˜s fight over the โ€šcombustion engine banโ€˜ was a waste of the publicโ€˜s attention. Performative politics. By 2035, collectors with special licenses may still want one, if they can pay for the fuel and find some last gas station. History doesnโ€˜t proceed in a linear fashion.

The Apache Hop open source data engineering platform is ramping up speed. 2.17 will be one of our biggest releases to date with major UI improvements, platform upgrades for Neo4j, MongoDB and tons of other fixes and new functionality.

Adalennis@adalennis.know.bi

First of all, Apache Hop 2.17 is coming, and this week showed it. UI polish, safer renames and saves, clearer dialogs, CVE fixes, updated deps, and Hop Web and metadata improvements. 21 PRs merged, 24 issues closed. Quiet progress, real impact. @hop.apache.org #apachehop

A big week: UI rough edges smoothed out, dialogs and toolbars behaving again, and long-standing papercuts fixed. Safer stream handling, cleaner transforms, #Azure managed identity support, better diffs, plus HTML/PDF support. Thanks to this week's contributors. @hop.apache.org #apachehop

The first full week of 2026 was a quiet one for Apache Hop, in the best way. Clearer logs, cleaner dialogs, safer pipelines, restored Parquet output, updated Beam, and key security fixes. 11 PRs merged, 14 issues closed. A solid start. Until next week. @hop.apache.org #apachehop
