August 2025 monthly summary for Effect-TS/effect: Focused on improving reliability of header processing in proxied environments by refactoring xForwardedHeaders middleware to consistently use x-forwarded-for for determining client IP and updating the host header only when x-forwarded-host is present. This streamlines proxy handling, enhances analytics accuracy, and reduces header-related anomalies. Commit c60956e18fe20841d39d0127c8c488af657ab936 implements the change, aligning with proxy reliability improvements (issue #5311).
