September 2025 (2025-09) monthly summary for redhat-developer/rhdh: Key features delivered include documentation updates for Dynamic Plugins Package Rename and marketplace configuration cleanup. Specifically, docs now reference @red-hat-developer-hub/cli instead of @janus-idp/cli across markdown files to reflect dynamic plugin changes (commit c6734b1252eb7b5be1bbbc31b8f9cc2728ddfac2). Also, catalog-integrations.yaml and scaffolder-integrations.yaml were removed from marketplace plugins to simplify configuration (commit 343eff352b0d31a0096b6043827e55baf4dbe3e8). No major bugs were fixed this month. Overall impact: reduces confusion for developers, lowers maintenance burden, and aligns documentation and configuration with current plugin architecture. Technologies demonstrated: markdown documentation best practices, change management via explicit commits, repository maintenance and governance of dynamic plugin configurations.
