dbt 0.19.2rc2

A second release candidate for v0.19.2.

Breaking changes

• Fix adapter.dispatch macro resolution when statically extracting macros. Introduce new project-level dispatch config. The packages argument to dispatch no longer supports macro calls; there is backwards compatibility for existing packages. The argument will no longer be supported in a future release, instead provide the macro_namespace argument. (#3362, #3363, #3383, #3403)

Fixes

• Fix references to macros with package names when rendering schema tests (#3324, #3345)
