silx settles into maintenance a release after its PySide6 migration
A side-by-side editorial comparison of Marquez and OpenObserve — release velocity, themes, recent moves, and the top alternatives to consider.
Marquez spent 2024 turning a lineage store into a UI, then stopped releasing
Marquez is the reference metadata server for OpenLineage, and this window captures a concentrated push on its web interface: a column-lineage page and redesigned lineage graph in 0.45.0, data quality and job status displays in 0.47.0, and a data observability dashboard in 0.50.0 showing event stats over 24-hour and 7-day windows with per-source, per-dataset and per-job views. The API side moved in step — job tagging, dataset schema versions, paging on jobs and dataset versions, job-to-job lineage, richer metrics labels. One contributor accounts for nearly all the web work in these entries. Note that the 0.45 through 0.49 releases were all stamped within three minutes of each other and in reverse version order, so publication timestamps here do not reflect release order.
After its largest release, OpenObserve is patching the seams.
v0.92.0 landed on 7 August with 836 commits and three new product surfaces - synthetic monitoring, Workflows v1, and an expanded AI observability set - after a long RC series. The two releases since are small: v0.92.1 fixed alert HAVING clause typing and put the MCP server setup page on the OSS build, and v0.92.2 adds a compactor delay setting and backports an MCP 404 fix for deployments running under a base URI. The 0.91 line is still receiving its own backports.

The arc is a backend project growing a front end: lineage data that existed in the API was progressively given pages, panels and paging, and by 0.50.0 the framing had shifted from lineage graph to observability dashboard. Tagging deepened in the same period, moving from dataset tags to field-level tags to job tags. That arc stops abruptly — 0.50.0 in October 2024 is the last entry, with nothing published in the roughly two years since.
The entries give no roadmap signal past 0.50.0, and the job-to-job lineage change was explicitly framed as a prompt for a wider parent/child hierarchy discussion that no later release picks up, so that hierarchy work is best read as unfinished rather than planned.

The 0.91 line is still receiving its own backports.
OpenObserve is trying to become the whole monitoring stack rather than the storage layer under one. Synthetic checks, incident workflows, and SLO measurement each replace a separate tool, and incident ingestion from external alert sources hedges the migration path for teams that cannot switch all at once. The MCP work running alongside - open sourced, then given a setup page in the OSS build, then fixed for base-URI deployments - shows the same data being aimed at agent clients rather than dashboards.
The post-GA patches are still landing on the new surfaces, so expect another 0.92.x before feature work resumes - most likely hardening synthetic monitoring and Workflows, which are the two least-exercised additions.
