+
+This is an automatically created issue which contains information about the version status of the documentations available on DevDocs. The results of this report can be used by maintainers when updating outdated documentations.
+
+Maintainers can close this issue when all documentations are up-to-date. This issue is automatically closed when the next report is created.
+

+

+- #{up_to_date_results.length} that #{up_to_date_results.length == 1 ? 'is' : 'are'} up-to-date (patch updates are ignored)
