Gel's new EdgeQL features and CLI workflows

Gel 6 introduces several enhancements aimed at improving the developer experience, notably through advancements in EdgeQL and the CLI. Key updates in EdgeQL include the removal of restrictions on using DML statements within user-defined functions, a shift to simpler and more intuitive scoping rules, and the addition of string interpolation for ease of use. Complex types can now be used more flexibly across various contexts, expanding the language's versatility. On the CLI front, Gel 6 introduces new automation features to ensure seamless integration of the data model with development workflows, including the use of hooks to automate tasks like code generation, data fixture loading, and test reruns in response to schema changes or project events. Additionally, the updated watch mode allows developers to configure triggers for code generation when query files are modified, enhancing the synchronization between schema and queries.
