v2025-02-18

New behavior

early_data_advanced. Allows query string parameters in early, or 0-RTT data.

Updates

image-manager. Added new options.

  • cloud​_wrapper​_enabled. Enables Cache+ to improve cache retention and performance. When enabled, Image and Video Manager stores derivatives in Cloud Wrapper.
  • cloud​_wrapper​_rollout​_start. Allows Cloud Wrapper to fetch from that cache for 30 days when a cache miss occurs before sending the request to the origin. Note that if using Image and Video Manager, the objects may already be in cache.
  • cloud​_wrapper​_url​_path. With cloud​_wrapper​_enabled set to true, specifies paths for which Image and Video Manager will store derivatives in Cloud Wrapper. You can use wildcards for each specified path, where ? matches a single character and * matches zero or more characters. Leaving this field empty means all Image and Video Manager derivative traffic will be stored in Cloud Wrapper.
