As we're in the process of formally removing `extra !=` due to being broken by design (https://discuss.python.org/t/ban-negative-extras-for-extras-marker/108022), we found this one usage and wanted give you a heads up about this feature being broken.\n\nWhen you try to `[uv] pip install feast[flink]`, it currently downgrades to installing 0.63.0, to avoid the unsatisfiable 0.64.0.\n\nCC @XuananLe","author":{"url":"https://github.com/konstin","@type":"Person","name":"konstin"},"datePublished":"2026-07-04T16:48:11.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":3},"url":"https://github.com/6583/feast/issues/6583"}
