What is Countly?

Countly's two LTS lines now get the same security fixes within a week of each other.

Countly ships security patches on two LTS lines, 25.03 and 24.05. In late October 25.03.56 moved the Docker images to Node.js 24.22.1 for a Brotli CVE and brought Python 3.12.15 to the A/B testing stack; 25.03.58 tightened tokens: app-restricted tokens must state their permissions, password changes revoke a member's tokens, and single-use tokens hold under concurrent requests. 24.05.55 then brought those same fixes to the older line, including the isolated-vm sandbox for custom hook code that 25.03 adopted in August.

What is Grafana Mimir?

Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.

Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.

5.0

Countly's two LTS lines now get the same security fixes within a week of each other.

◆ Current state

Countly ships security patches on two LTS lines, 25.03 and 24.05. In late October 25.03.56 moved the Docker images to Node.js 24.22.1 for a Brotli CVE and brought Python 3.12.15 to the A/B testing stack; 25.03.58 tightened tokens: app-restricted tokens must state their permissions, password changes revoke a member's tokens, and single-use tokens hold under concurrent requests. 24.05.55 then brought those same fixes to the older line, including the isolated-vm sandbox for custom hook code that 25.03 adopted in August.

◆ Where it's heading

The work is about access control and supply chain, not new analytics features. Tokens, sessions and login counting are being tightened release by release, and the 24.05 line is being pulled up to the 25.03 runtime (Node.js 22 for custom code, Python 3.12 with CmdStanPy for A/B testing) instead of being left on older stacks. Feature work shows up only in small items such as explicitly named databases and a licence payment-overdue banner.

◆ Prediction

Expect more paired patches as token and session hardening continues on both lines. The entries don't say how long 24.05 will keep receiving backports.

5.0

Mimir's feed is weekly chart bot noise; the 3.2 RC is where the breaking changes hide.

◆ Current state

Almost every entry in this window is an identical bot-generated Helm chart release — byte-for-byte the same body across seven tags. The one substantive release is the 3.2.0 RC, whose notes run past the feed's truncation point: continued Mimir Query Engine optimisation, native histogram support in more operators, per-tenant cost attribution trackers, and a tenant-fair compute worker pool on the ingester. Buried in its changelog are changes operators must act on — the embedded per-tenant Alertmanager web UI is gone, credential-bearing headers are now rejected at startup, and querier/store-gateway traffic requires coming from 3.1.

◆ Where it's heading

Mimir is deepening the query path rather than widening the product: most of 3.2 is MQE work, subquery spin-off, caching and elimination passes, largely behind experimental flags. The operational surface is growing in parallel — Kafka producer controls, mimirtool and kafkatool subcommands, SigV4 for shared API clients. The chart is versioned and released independently on a weekly bot cadence, which is why the feed reads as empty even in an active month.

◆ Prediction

The experimental MQE flags that landed in 3.2 are the ones to watch for promotion to default in 3.3, particularly subquery spin-off and scalar common subexpression elimination. Whether a 3.2.0 final follows this RC is not visible in the feed — only the RC has been published here.
