ITS has posted a patch-level release to address a small regression in the 2.19.0 release in which the .drush-lock-update file was removed from the five contrib modules updated in the 2.19.0 release.
This could have resulted in modules that are part of the UT Drupal Kit distribution accidentally being updated if a developer runs the drush pm-update or drush up commands.
If you had not already downloaded or applied the 2.19.0 update, you will now see the 2.19.1 update available in your Pantheon dashboard or the ServiceNow download page.
HOW TO UPDATE THE UT DRUPAL KIT
Complete instructions and download links for updating a UT Drupal Kit site are available on the documentation wiki. Pantheon site dashboards that use the UT Drupal Kit distribution should see the upstream updates available now; see the Pantheon documentation for more information on applying upstream updates.
Please review the changelog thoroughly, and always make backups of your code, files, and database before proceeding with an update!
