In December 2024, completed the primary documentation deliverable for ArgoCD-Keycloak integration, focusing on secure client authentication and PKCE workflows to enable seamless SSO using ArgoCD with Keycloak. This work emphasizes security, onboarding efficiency, and clear guidance for operators deploying Keycloak-ArgoCD integrations.

In November 2024, delivered a documentation-focused capability for EnterpriseDB/cloudnative-pg: added Docaposte as an adopter entry in ADOPTERS.md, including company name, contact, and rationale for using CloudNativePG, placed in chronological order to boost visibility and onboarding potential. This change is tracked in the commit 'docs: add Docaposte to ADOPTERS.md (#6145)' (c390c1dccce7ab8b5b817624f42dc3198db2128e). No major bugs fixed this month; effort focused on strengthening customer-facing documentation and adoption signals.
