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 OpenPanel?

OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.

OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.

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.

OpenPanel
ANALYTICS
5.0

OpenPanel tags three more note-free builds in one evening, reaching 3.16.4.

◆ Current state

OpenPanel tagged 3.16.2, 3.16.3 and 3.16.4 within about 80 minutes on October 27, after 3.16.1 the day before. Every entry is a build of main for supporters, installed with openpanel upgrade --supporter, and none carries release notes; public releases come from a separate self-hosting tag.

◆ Where it's heading

The 3.x line has climbed from 3.0.0 to 3.16.4 in under two weeks, with each bump published as a bare build. The cadence shows active development, but the feed gives no way to see what changed or which builds matter.

◆ Prediction

Expect more note-free supporter builds; a public self-hosting release with notes is the first point where the content of 3.x becomes visible.
