Apache Iceberg
Iceberg 1.12 drops Spark 3.4 and starts laying groundwork for the v4 table spec.
A side-by-side editorial comparison of Delta Lake and OpenSearch Dashboards — release velocity, themes, recent moves, and the top alternatives to consider.
Delta Lake's public stream is release mechanics; Kernel builds now carry a 4.5.0 label.
Recent Delta Lake activity is mostly release mechanics: 4.4.0 and 4.4.1 tags, a stream of Databricks runtime kernel builds, and patch releases. The newest build is labelled Delta Kernel 4.5.0, the first sign of the next minor line. The substantive user-facing work sits in patches such as the 3.3.3 fix for log cleanup deleting files still needed for time travel.
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.

The project keeps 3.x and 4.x alive and spends its public changelog on correctness and catalog integration rather than new table features. Kernel builds tagged for Databricks runtime suggest Kernel development is paced by Databricks' own release train, with the open-source releases following.
A 4.5.0 open-source release is the likely next notable entry given the kernel version label, but the entries don't say what it will contain.

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