+ *) mod_md: update to version 2.6.5
+ - New directive `MDInitialDelay`, controlling how longer to wait after
+ a server restart before checking certificates for renewal.
+ [Michael Kaufmann]
+ - Hardening: when build with OpenSSL older than 1.0.2 or old libressl
+ versions, the parsing of ASN.1 time strings did not do a length check.
+ - Hardening: when reading back OCSP responses stored in the local JSON
+ store, missing 'valid' key led to uninitialized values, resulting in
+ wrong refresh behaviour.
