Release Overview

Changes That May Impact Your Site the Most

  • File Editor Size Limit. The file editor will now only open files that are smaller than a configurable size limit. You can configure the maximum file size that can be opened by setting the OOD_FILE_EDITOR_MAX_SIZE environment variable. The default is 12 MB.
  • Passenger and Metrics Collection. Passenger has been patched for reduced metrics collection due to efficiency impacts found by CSC - IT Center for Science. Previously, all PUNs paused every 5 seconds to collect data. This duration is now configurable through OOD_OVERRIDE_PASSENGER_ANALYTICS_COLLECTION_SLEEP_TIME_SECONDS, which defaults to 30 seconds. Additionally, each PUN operates on its own timer, improving overall system performance. Centers can revert to the previous behavior (synchronizing every 5 seconds) by defining the environment variable OOD_OVERRIDE_PASSENGER_ANALYTICS_COLLECTION_RESTORE_UPSTREAM_BEHAVIOR. Any defined value, even an empty string or false, is interpreted as true.

Added

  • Passenger Telemetry. Passenger telemetry has been disabled by default. If needed, you can re-enable it by setting the passenger_disable_anonymous_telemetry configuration to off in nginx_stage.yml.
  • Encrypted Password Fields. password_field form widgets are now encrypted when stored, enhancing security.

Fixed

  • Job Composer Fix. The Job Composer now correctly handles erroneous input when creating templates, fixing issue #3426.
  • Dashboard Logging Fix. The dashboard’s configuration class now uses $stderr.puts instead of Rails.logger.warn for error logging, as Rails was unavailable in this context, which caused errors.
