A new section «crt-store» has been added to the configuration for setting up the storage and usage of TLS certificates. Unlike the previously available configuration option crt-list, in crt-store the certificate storage is separate from its use in the frontend, allowing each component of the certificate (files with certificates, keys, and OCSP data) to have an individually specified storage location.\n

A new configuration directive «guid» has been added, which can be used in the «frontend», «backend», and «listen» sections. This directive ties a unique identifier to these sections, enabling the associated statistics to be retained after a restart (the Stats page state will not be reset). A new command «dump stats-file» has been added for saving statistics to a file, and a new configuration directive «stats-file» has been added for reading from a file after a restart.\n
