Apr 1, 2026

April 2026 (2026-04) — Kong/developer.konghq.com delivered OAuth2 authentication for PostgreSQL, enabling SSO and strengthening security for developer workflows. The feature was implemented with a focused commit and supported by a comprehensive docs/config update to reflect the new method. Key documentation improvements include updates to postgresql-oauth.md, added FAQs, and alternative formatting (Mermaid diagrams, Liquid tables) to improve discoverability and accuracy. The work also involved updating access/config references (pghba and related gateway docs) to align with the new OAuth integration. Collaboration included code review responses and AI-assisted tooling, with the primary commit 459018a1dc3cc0b2a077e1030e334068cadd03a1 and multiple doc-oriented refinements.

In February 2026, Kong/developer.konghq.com delivered updated Kafka 4.0 support documentation for 3.10+, including explicit notes on message compression and format customization limitations. No major bugs were fixed this month. Impact: clearer guidance for Kafka 4.0 adoption, reducing misconfigurations and support queries, enabling faster onboarding for developers. Technologies/skills demonstrated: documentation authoring, change-tracking with commit 41f3f736826c1ab46a5988ae80395917c77dfcd1 (#4012), and alignment of docs with code changes.

February 2025: Delivered a configurable ACAO header option in the CORS plugin for Kong/kong, enabling skipping the Access-Control-Allow-Origin header when Origin is absent. This preserves backward-compatible behavior while reducing unnecessary headers in Origin-less requests, improving privacy and bandwidth efficiency for affected deployments. Implemented as a feature commit 87e9a7619acc324e04b1b60214be5f9ce2c0c6ec (feat(cors): add an option to skip return ACAO when no origin in request (#14155)).

January 2025 monthly summary for Kong/kong: Focused on expanding test coverage in clustering for the Correlation-ID plugin. Delivered RPC synchronization testing across clustering configurations, covering both synchronous and asynchronous RPC modes, with rpc_sync set to 'on'. Adjusted test setup to validate correct database initialization and plugin loading in clustered environments. This work increases reliability of distributed deployments and provides CI-ready validation for clustered operation of correlation-id.

December 2024 monthly summary for Kong/kong focused on stability and reliability in RPC-synced deployments. Delivered a bug fix improving data plane readiness reporting to correctly signal 'ready' status after configuration across RPC synchronization scenarios. Implemented targeted tests and conditional logic to cover varying RPC sync configurations, with a clustering test ensuring readiness visibility remains correct during topology changes. The work reduces false negatives in readiness signals and enhances deployment safety.
