duckdb/duckdb最新发布版本:v1.0.0(2024-06-03 21:08:46)

This preview release of DuckDB is named "Ferruginea" after the Andean Duck.

Binary builds are listed below. Feedback is very welcome.

Note: This release should be backwards-compatible wrt the on-disk storage format, but the next release may very well be incompatible again. So please don't rely on this just yet. We suggest you use the EXPORT DATABASE command with the old version followed by IMPORT DATABASE with the new version to migrate your data. See the documentation for details.

Also note: DuckDB is switching to semantic versioning. Version numbers look like this: MAJOR.MINOR.PATCH with changes to

MAJOR version when you make incompatible API changes,
MINOR version when you add functionality in a backwards compatible manner, and
PATCH version when you make backwards compatible bug fixes.

However, note that because MAJOR is currently 0, "Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable."

Below a list of changes in this release
