What is Countly?

Countly ripped out its custom-code sandbox and rebuilt its Docker stack from scratch in a single LTS drop.

Countly is in an extended security hardening cycle, maintaining two parallel LTS lines — 25.03.x and 24.05.x — with coordinated patch releases. The 25.03.52-LTS was structurally significant: Docker images rebuilt as multi-stage on Debian 13 and Node.js 24 to strip compilers and build tooling from production images, the legacy v8-sandbox replaced by isolated-vm eliminating network, filesystem, and process access from custom hooks, and the A/B testing backend migrated from end-of-life Python 3.8 and pystan to Python 3.12 and cmdstanpy. The 25.03.53 and 24.05.53 patches that followed addressed XSS, OIDC session handling, and embedded widget cross-origin policies.

What is TimescaleDB?

TimescaleDB 2.31 speeds columnstore UPDATE/DELETE and previews a new integer compressor.

TimescaleDB ships on a steady biweekly cadence where most releases are bug-fix patches for the columnstore, SkipScan and continuous aggregates. Feature releases have chipped at the cost of big hypertables: 2.30.0 made last-point LIMIT queries independent of chunk count, and 2.31.0 vectorizes UPDATE and DELETE on compressed data, adds non-blocking move_to_columnstore(), and previews an Adaptive Integer Compressor claiming up to 20% better integer compression. The 2.30.x patches fixed duplicate rows and crashes from the previous release's new planner node.

6.3

Countly ripped out its custom-code sandbox and rebuilt its Docker stack from scratch in a single LTS drop.

◆ Current state

Countly is in an extended security hardening cycle, maintaining two parallel LTS lines — 25.03.x and 24.05.x — with coordinated patch releases. The 25.03.52-LTS was structurally significant: Docker images rebuilt as multi-stage on Debian 13 and Node.js 24 to strip compilers and build tooling from production images, the legacy v8-sandbox replaced by isolated-vm eliminating network, filesystem, and process access from custom hooks, and the A/B testing backend migrated from end-of-life Python 3.8 and pystan to Python 3.12 and cmdstanpy. The 25.03.53 and 24.05.53 patches that followed addressed XSS, OIDC session handling, and embedded widget cross-origin policies.

◆ Where it's heading

Countly is hardening its self-hosted security posture — the isolated-vm switch and Docker rebuild reduce attack surface without changing the product surface for end users. Running two LTS tracks simultaneously signals a maturing enterprise customer base that cannot upgrade on a quarterly cadence. Feature development in journey_engine and content continues on a separate lane from the security work, suggesting the two concerns are intentionally decoupled.

◆ Prediction

The Node.js 22/24 migration will propagate to additional components. The isolated-vm change will likely prompt tighter documentation of what custom code can and cannot access. Dual LTS maintenance continues as long as significant deployments remain on 24.05.x.

TimescaleDB

5.0

TimescaleDB 2.31 speeds columnstore UPDATE/DELETE and previews a new integer compressor.

◆ Current state

TimescaleDB ships on a steady biweekly cadence where most releases are bug-fix patches for the columnstore, SkipScan and continuous aggregates. Feature releases have chipped at the cost of big hypertables: 2.30.0 made last-point LIMIT queries independent of chunk count, and 2.31.0 vectorizes UPDATE and DELETE on compressed data, adds non-blocking move_to_columnstore(), and previews an Adaptive Integer Compressor claiming up to 20% better integer compression. The 2.30.x patches fixed duplicate rows and crashes from the previous release's new planner node.

◆ Where it's heading

The columnstore is being made a place where data can be changed, not just queried: chunk-level locking for DML in 2.29, vectorized DML and non-blocking compression in 2.31. Granular continuous-aggregate refresh is maturing alongside with APIs, views and refresh statistics. Each minor release is still followed by correctness patches.

◆ Prediction

2.32.0 will enable the Adaptive Integer Compressor by default, as the 2.31 notes state. Expect a couple of 2.31.x patches for the new DML and compression paths first.
