Swarm Storage has significantly increased the efficiency of refreshing cluster hardware and retiring whole chassis. The processes for retiring volumes and cleaning up over-replication have been are optimized. (SWAR-7765)
For implementations that deliver content directly over the web, Swarm Storage now provides cluster settings for restricting which headers are returned for GET and HEAD responses, using either a whitelist or blacklist approach. Filtering the response headers best serves those needing to conserve bandwidth (eliminating as many bytes as possible when serving content) and those needing enhanced security (to reveal as little as possible about the content and its context). (SWAR-7695)
