# CiviCRM: Evaluate a release candidate ## Check the build Navigate to http://download.civicrm.org/latest and verify that the RC has a release with a suitable timestamp. (If the RC is missing, inspect the records for https://test.civicrm.org/job/CiviCRM-Publish/) ## Create the hydra In case there have been significant changes in the CMS integrations, in distmaker, or in the installer, you should double-check that the tarballs and installers still work as expected. If you have a system with `civibuild`, then you can use the related command `civihydra` to spin up empty sites and download the tarballs. For example: ``` civihydra create https://download.civicrm.org/latest/civicrm-RC-drupal.tar.gz civihydra create https://download.civicrm.org/latest/civicrm-RC-wordpress.zip civihydra create https://download.civicrm.org/latest/civicrm-RC-joomla.zip civihydra create https://download.civicrm.org/latest/civicrm-RC-backdrop.tar.gz # civihydra create https://download.civicrm.org/latest/civicrm-RC-drupal6.tar.gz ``` or build all of them in one command: ``` civihydra create https://download.civicrm.org/latest/civicrm-RC-drupal.tar.gz https://download.civicrm.org/latest/civicrm-RC-wordpress.zip https://download.civicrm.org/latest/civicrm-RC-joomla.zip https://download.civicrm.org/latest/civicrm-RC-backdrop.tar.gz ``` The `civihydra` command will print out instructions to complete each installation manually. If you missed the instructions, display them again by running `civihydra show`. ## WIP We should be defining more processes to evaluate RCs.
