What is ntopng?

ntopng grew from traffic monitor into asset inventory and vulnerability scanner — one major at a time

ntopng ships roughly one stable major a year. The 6.x line added vulnerability scanning and CVE support, then an Asset Inventory and Digital Twin with an assets dashboard, then autonomous-system dashboards with native ClickHouse Cloud SSL and a direct flow dump mode for real-time export. The last published release was 6.6 in November 2025, so this feed is currently quiet.

What is TimescaleDB?

TimescaleDB is paying down correctness debt in its columnstore query paths.

The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.

ntopng grew from traffic monitor into asset inventory and vulnerability scanner — one major at a time

◆ Current state

ntopng ships roughly one stable major a year. The 6.x line added vulnerability scanning and CVE support, then an Asset Inventory and Digital Twin with an assets dashboard, then autonomous-system dashboards with native ClickHouse Cloud SSL and a direct flow dump mode for real-time export. The last published release was 6.6 in November 2025, so this feed is currently quiet.

◆ Where it's heading

Each major has annexed an adjacent category rather than deepening flow analysis: security posture in 6.0, asset management in 6.4, and infrastructure-scale visibility in 6.6. Underneath, ClickHouse has steadily replaced the older storage paths, moving from an option in 5.2 to the assumed backend with a real-time export mode. The result is a product competing well outside its original network-monitoring lane.

◆ Prediction

With the last release nine months old, the next major is overdue; based on the pattern it would extend the asset and security surfaces rather than the flow engine.

5.0

TimescaleDB is paying down correctness debt in its columnstore query paths.

◆ Current state

The 2.29 line is in patch mode after 2.29.0 landed chunk exclusion for DML in late July. 2.29.1 carried three security advisories alongside compression fixes, and 2.29.2 is bug fixes only - most of them wrong-results bugs in the columnar execution paths rather than crashes. Every release note in this window recommends upgrading at the next opportunity.

◆ Where it's heading

The feature work of 2.27 and 2.28 - vectorized filter evaluation, first/last derived straight from columnstore batch metadata, sparse indexes, SkipScan on compressed data - has been followed by a steady stream of fixes to those same code paths. 2.29.2 alone repairs SkipScan dropping uncompressed rows, sparse-index pushdown returning wrong results for IS NULL, and gapfill over window aggregates. That is the normal cost of pushing query optimizations into a compressed columnar store, and the project is working through it release by release rather than pausing.

◆ Prediction

With three consecutive patch releases on the 2.29 line and no new highlighted features since 2.29.0, the next minor is likely to resume the columnstore performance work - though the density of wrong-results fixes suggests more patches first.
