 Each branch in this repository targets a specific version of DuckDB. Note that these branches will be continually updated to ensure the build environment is functional for that version of DuckDB.
-Also note that at some point, support for versions will be dropped. Currently, we aim to support the latest 2 DuckDB versions, to allow extensions devs to transition to a new DuckDB version.
