DuckLake follows semantic versioning. Larger new features are introduced in minor versions, while patch versions mostly contain bugfixes.

DuckLake is expected to mature over the coming period with the DuckLake v1.0 release planned in 2026.

Upcoming Releases

Upcoming releases are shown in the table below. Please note that these dates are tentative and DuckLake maintainers may decide to push back release dates to ensure the stability and quality of releases. DuckLake specification releases are currently tied to ducklake extension releases, this may change in the future. It is also worth mentioning that some ducklake extension releases may have a dependency on DuckDB and therefore will need to adjust to the DuckDB release calendar.

Compatibility Matrix

Currently, the DuckLake specification and the ducklake DuckDB extension are currently released together. This may not be the case in the future, where the specification and the extension may have different release cadences. It can also be the case that the extension needs a DuckDB core update, therefore DuckDB versions are also included in this compatibility matrix.

DuckDB version	Extension version	Spec. version
1.4.x	0.3	0.3
1.3.x	0.2	0.2
1.3.x	0.1	0.1
