What is DuckDB?

Six releases, all patches — this window shows DuckDB's maintenance machine, not its roadmap

Every entry in this window is a bugfix release, and two release lines are being maintained side by side: 1.5.5, 1.5.4, 1.5.3, 1.5.2 and 1.5.1 on the current branch, with 1.4.5 shipped the same day as 1.5.4 for users still on the older line. The content is backports, race-condition fixes, extension and build plumbing, and in 1.5.5 a backport of out-of-bounds security fixes. Feature releases sit outside this window, so what is visible is the patch cadence rather than the direction.

What is OpenHouse?

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

Six releases, all patches — this window shows DuckDB's maintenance machine, not its roadmap

◆ Current state

Every entry in this window is a bugfix release, and two release lines are being maintained side by side: 1.5.5, 1.5.4, 1.5.3, 1.5.2 and 1.5.1 on the current branch, with 1.4.5 shipped the same day as 1.5.4 for users still on the older line. The content is backports, race-condition fixes, extension and build plumbing, and in 1.5.5 a backport of out-of-bounds security fixes. Feature releases sit outside this window, so what is visible is the patch cadence rather than the direction.

◆ Where it's heading

The pattern is a project treating its previous minor as a supported branch rather than abandoning it — same-day 1.4.5 and 1.5.4 releases, with fixes explicitly backported from the newer line. Patch spacing has tightened over the window, from roughly two months between 1.5.1 and 1.5.2 to about five weeks between 1.5.4 and 1.5.5. Each release also points at an announcement blog post, so the substantive narrative lives off the feed.

◆ Prediction

The visible entries only support a continuation of the same pattern: further patch releases on both the 1.5 and 1.4 lines, with fixes backported between them. Nothing in this window signals what the next feature release contains.

OpenHouse breaks ground on Iceberg views while tightening storage lifecycle and authorization

◆ Current state

OpenHouse (LinkedIn's managed Iceberg tables service) is shipping at a rapid v0.5.x pace with multiple improvements per week. Recent work spans three areas: storage lifecycle management (native snapshot expiration with reference age defaults, orphan file reclamation), authorization hardening (routing RTAS operations through proper table privilege checks), and the first scaffolding for Iceberg view support (entityType discriminator, table-scoped HTS queries).

◆ Where it's heading

The entityType discriminator in v0.5.490 is the most directional move in this window — it creates the data model prerequisite for treating views as first-class entities alongside tables, something OpenHouse has not supported. Storage lifecycle work is converging on Iceberg-native mechanisms, reducing custom expiration logic. The post-commit operations framework in v0.5.492 is infrastructure that will allow OpenHouse to add downstream hooks (compaction triggers, notifications) without catalog coupling.

◆ Prediction

Iceberg view read support will arrive in the next several releases, building on the discriminator and HTS scaffolding now in place. The authorization model for views will be an open question — watch whether they reuse the table ACL path or introduce a parallel model.
