+- The default value of the SSL "CipherList" variable has been changed to
+  "HIGH:!aNULL:@STRENGTH:!SSLv3" (OpenSSL) and "SECURE128:-VERS-SSL3.0"
+  (GnuTLS) to disable the old SSLv3 protocol by default.
+  To enable connections of clients still requiring the weak SSLv3 protocol,
+  the "CipherList" must be set to its old value (not recommended!), which
+  was "HIGH:!aNULL:@STRENGTH" (OpenSSL) and "SECURE128" (GnuTLS), see below.

 Differences to version 20.x
 
 - Starting with ngIRCd 21, the ciphers used by SSL are configurable and

 - When adding GLINE's or KLINE's to ngIRCd 21 (or newer), all clients matching
   the new mask will be KILL'ed. This was not the case with earlier versions
