The preview (nightly) builds provide development versions of DuckDB. As such, they are constantly in flux and they are less suitable for production use than the stable releases of DuckDB. You should only use these releases if you are looking for recent bugfixes or optimizations.

There are currently the following DuckDB versions under development:

• v1.4: the LTS release.
• v1.5: the current stable DuckDB release.
• v2.0: the next DuckDB version, in an early stage of the development.

Note that for most users, we recommend the stable DuckDB releases.
