qStudio is a development-tooling preview, separate from the QQQ 4.0 framework release. Installation, client support, data handling, and subscription terms need confirmation with an available release.
The earlier cloud-launch wording overstated availability. qRun hosting is a separate product preview; this archive does not establish a live service, pricing, or SLA.
Automatic GraphQL generation is not in the verified QQQ 4.0 release scope. Use the actual middleware/API contracts of the selected application; an additional GraphQL layer needs separate implementation and tests.
Processes combine metadata with Java backend steps. Implement business behavior, error handling, and recovery explicitly. The earlier visual designer and automatic retry examples were not verified APIs.
The 4.0 train includes relational, MongoDB, SQLite, file-system, S3, and REST modules. Supported operations differ. Do not assume an announced connector name establishes DynamoDB support or cross-backend transactions.
Authentication and permission facilities require application configuration and denied-access tests. The earlier encryption and security-policy snippets were not verified framework APIs. Configure identity, TLS, storage encryption, and audit needs explicitly.
The catalog shows component previews. A listing does not establish a published Maven artifact or 4.0 compatibility. Start from the real application, data, or extension templates and verify the selected component in a host application.
The dashboard remains version 0.40.0 in the 4.0 release train. A frontend replacement is outside this release scope. Use the sample to review the current table, process, and widget behavior.
QQQ has reporting and export facilities. Configure the required report, format, backend, and delivery workflow in an application. The earlier visual-builder and endpoint examples were not verified 4.0 contracts.
Validate the assembled QInstance and implement field and business rules using actual framework APIs. The earlier fluent validation snippets were illustrative and did not match the released interfaces.
QQQ uses Java metadata and backend steps to build data applications. Start with Java 21, Maven, and the source-based sample. The earlier Gradle quickstart and fixed-time setup promise have been replaced with reproducible instructions.
