Full Changelog: v1.3.0...v1.3.1

v1.3.0

Note

Unfortunately this release contains a regression when reading DECIMAL types through arrow. DuckDB v1.3.0 contains new physical types for decimals and will try to use the smallest possible representation for decimals depending on their logical scale and width - but arrow-rs currently only supports 128 and 256-bit decimals (not e.g. 32-bit used with smaller widths), and will thus throw an error when these smaller decimals are read from DuckDB. Regardless of when/if arrow-rs adds support for smaller decimal types, the plan is to make this behavior configurable in DuckDB v1.3.1.
