    • The AstToSqlVisitor now implements basic, standard SQL and functions as a base class for dialects.

    • The Athena dialect now lives in AstToAthenaSqlVisitor.

[0.7.2] - 2022-12-19

Fixed

[0.6.0] - 2022-10-28

Changed

  • Django; Rework Django query transformer to use Django query nodes more. With the release of Django 4, we can now use Lookup, Function, and other Django query nodes in queries directly instead of relying on the keyworded syntax. For older Django versions, we can still transform those nodes to the keyworded syntax.

  • Deps; Upgraded Sphinx and the ReadTheDocs theme.

Fixed

Changed

  • QA: Upgraded linting libraries.

[0.4.2] - 2021-12-19

Added

  • Docs: Include contribution guidelines and changelog in the main documentation.

Changed

Changed

  • AstToDjangoQVisitor now builds subqueries for any()/all() itself, instead of relying on SubQueryTokens and a seperate visitor.
