9.0.0

9.0.0 - 2026-06-16

Summary

This major version introduces matrix.yml whose results are generated by the nox session matrix:generate.

Projects can extend BaseConfig with additional matrix values when they need to expose
more entries to the workflows.

class Config(BaseConfig):
    extra_matrix_value: str = "extra"

    @computed_field  # type: ignore[misc]
    @property
    def computed_matrix_value(self) -> str:
        # This can be requested when generating the matrix. If it is a simple string value,
        # like is shown here, then the code will automatically wrap it in an array.
        return f"{self.project_name}-computed"

The corresponding nox sessions (matrix:all, matrix:exasol, and matrix:python) will
remain available until September 15, 2026, to provide a transition period for existing projects.

At the same time, the workflows matrix-all.yml, matrix-exasol.yml, and matrix-python.yml
are deprecated and are no longer maintained by the exasol-toolbox. You can still use
these workflows in your project until you transition fully to using matrix.yml.
