Citus
Citus keeps three Postgres branches alive while chasing each new major
A side-by-side editorial comparison of Apache Kylin and Apache Iceberg — release velocity, themes, recent moves, and the top alternatives to consider.
Kylin ships once a year with empty release notes and a native engine nobody is being told about.
Apache Kylin's release stream is close to silent. Four of the six most recent tags carry nothing but the Maven release plugin's own commit message, and 5.0.4 in July 2026 arrived ten months after 5.0.3 with no notes at all. The last release that documented anything was 5.0.2 in April 2025, covering internal-table caching, partition-aware file merging and Gluten jar loading order.
Iceberg's release cadence is now backports and CVE patches across three live minor lines.
The project is maintaining 1.9.x, 1.10.x and 1.11.x concurrently, and the visible work is overwhelmingly maintenance: dependency bumps, backported fixes, and a steady stream of correctness repairs around nullability, deletes and the REST catalog. 1.10.2 in particular is almost entirely backports plus a CVE fix in a compression dependency.

The substance is in 5.0.0 and its follow-ups: Gluten with a ClickHouse backend as a native execution engine, internal tables, streaming and fusion models. That is a real architectural bet on native vectorised execution, but the project is not communicating it — releases ship as bare tags, and the gap between 5.0.3 and 5.0.4 suggests development has thinned to a trickle. For anyone tracking Kylin from the outside, the release feed is effectively no signal.
The entries do not support a confident call on what ships next; with untitled tags roughly annually, the useful signal about Kylin's direction will come from JIRA and the mailing list rather than from releases.

The feature story lives in the minor releases and the spec, not the patches — Flink 2.0 support, Variant type work reaching Parquet readers, and repeated REST catalog validation fixes point at a format spending its effort on engine breadth and on the REST catalog as the standard access path. The patch stream shows a format mature enough that its hardest problems are now schema-evolution edge cases and cleanup-on-failure semantics.
Expect continued parallel maintenance of the 1.10.x and 1.11.x lines with backports dominating, and the next substantive work to land in Variant type coverage and REST catalog behaviour rather than in the core table spec.
