Full Changelog: v0.10.3...v1.0.0

This is a bug fix release for various issues discovered after we released 0.10.2. There are no new major features, just bug fixes. Database files created by DuckDB v0.10.* or v0.9.* can be read by DuckDB v0.10.3.

Highlights

Even though this is "only" a bug fix release, there have been some major areas of work that warrant a separate mention:

• We have added a feature to update extensions using the UPDATE EXTENSIONS syntax #11677
• There have been some serious internal improvements around checkpointing, most notably, checkpoints can run while other connections are reading, and no longer block new connections while checkpointing #11918. Also, FORCE CHECKPOINT no longer actively cancels transactions, it now waits until it can checkpoint #12061
• DuckDB now has native support to load data from HuggingFace using the hf:// prefix #11831
• We have slightly changed NULL casting behaviour with the MAP type #11745
• The Java JDBC driver has been moved to its own repo: https://github.com/duckdb/duckdb-java #11873

This release of DuckDB is named "Fusca" after the Velvet Scooter native to Europe.

Note: The on-disk storage format is backwards-compatible with the 0.9 releases of DuckDB. For details, please see the release announcement blog post.

Also note that we've dropped' the "Preview" designation with this release. DuckDB has matured quite a bit since we started creating releases back in 2019, and it is no longer appropriate.

This is a bug fix release for various issues discovered after we released 0.9.0. There are no new features, just bug fixes. Database files created by DuckDB v0.9.0 can be read by DuckDB v0.9.1 (i.e. v0.9.1 is backwards compatible with v0.9.0 and vice versa).

This preview release of DuckDB is named "Undulata" after the aptly named Yellow-billed duck native to Africa.

Note: Again, this release introduces a backwards-incompatible change to the on-disk storage format. 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.
