In July 2025, nats.docs delivered a documentation improvement for the HeadersOnly configuration by moving it from a pull-specific section into the general configuration area and clarifying applicability to both push and pull consumers. This enhances usability, reduces potential misconfigurations, and supports faster onboarding and fewer support queries. The change is backed by commit 7e5f141bd75eb3c3926906cfd117ce7f1927a734 (#852). No major bugs were recorded for this repo this month.
