-nGQL is a project in progress. New features and optimizations are done steadily. There can be differences between syntax and implementation. Submit an [issue](https://github.com/vesoft-inc/nebula-graph/issues) to inform the Nebula Graph team if you find a new issue of this type. Nebula Graph 2.0 or later releases will support [openCypher 9](https://www.opencypher.org/resources).
