The latest 1.4.2 update of the Pantheon MU Plugin is now available. This update fixes a bug in the pantheon_cache_default_max_age filter added in 1.4.0 where the filtered value was not being used in the cache control headers. This bug was found by Brian Perondi and surfaced in our Community Slack Workspace. We appreciate the report and the fix will be available with the next WordPress release. Composer-based WordPress installs can get the update right away by running composer update.
