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 OpenSearch Dashboards?

This feed samples OpenSearch Dashboards; its latest entry is a 2.19.7 notes commit.

The feed carries release-branch commits rather than release notes, so the visible record is five entries from July 2025 to October 2026. The latest, on October 16, adds release notes for 2.19.7, which shows the 2.19 maintenance line is still being patched alongside 3.x. Before that, the 3.8.0 notes commit in July and Vega CVE fixes on 2.19 are the only substantive items.

Apache Iceberg vs OpenSearch Dashboards: 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.

O2.5

This feed samples OpenSearch Dashboards; its latest entry is a 2.19.7 notes commit.

◆ Current state

The feed carries release-branch commits rather than release notes, so the visible record is five entries from July 2025 to October 2026. The latest, on October 16, adds release notes for 2.19.7, which shows the 2.19 maintenance line is still being patched alongside 3.x. Before that, the 3.8.0 notes commit in July and Vega CVE fixes on 2.19 are the only substantive items.

◆ Where it's heading

The 2.19 line keeps getting maintenance releases while 3.x moves on. The feed is too sparse to show what either line is shipping.

◆ Prediction

Expect further 2.19.x and 3.x notes commits; what they contain is unclear from this feed.
