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 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.
{% if site.data.upcoming_releases.size > 0 %}
| Release date | Spec. version | Extension version |

In the following, we list DuckLake's past releases.
{% assign latest_version_number = "0.0" %}
{% for row in site.data.past_releases %} {% if row.ducklake_extension > latest_version_number %} {% assign latest_version_number = row.ducklake_extension %} {% endif %} {% endfor %}
| Release date | Spec. version | Extension version | Announcement post | |----------------:|----------------------------------:|--------------------------------:| {% for row in site.data.past_releases %} {%- if row.ducklake_extension == latest_version_number %} {% assign docs_version = "stable" %} {% else %} {% assign docs_version = row.ducklake_extension %} {% endif -%} | {{ row.release_date }} | [{{ row.ducklake_spec }}](/docs/{{ docs_version }}/specification/introduction) | [{{ row.ducklake_extension }}](/docs/{{ docs_version }}/duckdb/introduction) | [post]({{ row.release_notes }}) | {% endfor %}
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.
{% if site.data.compatibility_matrix.size > 0 %}
| DuckDB version | Extension version | Spec. version |
|---|---|---|
| {%- for release in site.data.compatibility_matrix %} | ||
| {{ release.duckdb_version }} | {{ release.ducklake_extension_version }} | {{ release.ducklake_spec_version }} |
| {%- endfor %} | ||
| {% else %} | ||
| There is no compatibility matrix at the moment. Please check back later. | ||
