Jackett
A daily indexer-repair treadmill: Jackett patches tracker definitions as fast as trackers change.
A side-by-side editorial comparison of Contour and Dependency-Track — release velocity, themes, recent moves, and the top alternatives to consider.
Three supported branches, patched in lockstep within the same minute.
Contour maintains 1.31, 1.32 and 1.33 concurrently and releases them together — the February batch went out across three branches inside two minutes, and the March batch did the same. The content is almost entirely inherited: Envoy bumps to pick up security fixes, Go updates, and a gRPC update for a CVE that Contour explicitly notes it is not affected by.
A v5 release candidate train carrying a database migrator that has to work on the first try.
Dependency-Track is deep in a 5.0.0 release candidate series, cutting rc.2 through rc.5 within a single week. A large share of every release is the v4-migrator: BIGINT casts during extract, ANALYZE on staging tables before transform, component dedup before joining repo metadata, cross-schema type dependencies, trigger deactivation, permission table bootstrap. Nearly every commit in the window is authored by a single maintainer.

This is a proxy whose release cadence is governed by its data plane rather than its own feature work. Envoy security releases set the schedule, and Contour's job is to bump, verify compatibility and ship across every supported branch simultaneously. The changes that do originate in Contour are operational sharp edges found in production: an HTTPProxy CRD schema wrongly marking a status error field as required, which broke load balancer status updates, and shutdown-manager being CPU-throttled at a 50m limit.
The next release will almost certainly be another simultaneous three-branch batch triggered by an Envoy security bump, since both batches in this window followed exactly that pattern.

This is a major version defined by what it removes and how safely it moves people across. rc.2 dropped the compatibility shim translating v4-era alpine.* and unprefixed property names to dt.* equivalents, and made the API server refuse to start on a legacy key rather than silently misconfigure. Around that migration work, the policy engine keeps gaining inputs — component hash mismatch conditions, latest version publish timestamps exposed to CEL — and latest-version detection is being tuned per ecosystem so Maven reports stable releases rather than prereleases.
Expect further release candidates focused on migrator robustness before 5.0.0 goes stable, since four of them in one week were still finding extract and transform bugs in the same code path.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
They serve adjacent needs but don't currently overlap on shipped themes. Contour and Dependency-Track are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity.
