What is Apache Iceberg?

Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.

Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.

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.

Apache Iceberg vs Countly: editorial side-by-side

A0.0

Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.

◆ Current state

Apache Iceberg maintains several minor lines at once, and most visible work is backports and dependency updates. 1.12.0 on September 30 is broader: it removes Spark 3.4 support, adds V4 groundwork such as relative paths in the spec and Parquet or Avro manifests, adds a REST unregister-table endpoint and content stats in the spec, and writes shredded Variant from Flink. Kafka Connect now reports commit failures instead of swallowing them.

◆ Where it's heading

The project is moving from maintenance-only releases back to spec work, with V4 pieces landing in stages. Older engine versions are being dropped as that happens.

◆ Prediction

Expect more V4 spec and core pieces in 1.13 and patch releases on 1.11 and 1.12; a V4 release date is not visible in the entries.

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.
