• Maintenance: Highly active project with frequent updates (last updated within the week) ensuring Day 0 support for new Spring Boot milestones.

Ongoing maintenance

Configuration metadata

[x] Starter provides metadata, including documentation, for all its configuration properties.
Configuration properties use the springdoc. prefix and include full description metadata for IDE autocomplete.

Build system integration

The library utilizes standard Spring Boot auto-configuration. No custom build plugins are required for dependency resolution, though a dedicated Maven/Gradle plugin is available for build-time JSON generation.
