+## 5.7.7
+**`(chore):`** Reduce verbose logging during OpenAPI parsing by moving individual example
+validation warnings to debug level. The per-API example validation summary
+is still shown at warn level.
+
+
+**`(fix):`** Improve logging when APIs are skipped during docs generation. Skipped APIs
+now log at error level (instead of warn) with the API name and a clear
+reason. Repetitive per-endpoint frontmatter warnings are aggregated into
+a single summary line per API.
