+=head1 BUGS
+
+The B<SSL_ERROR_SYSCALL> with B<errno> value of 0 indicates unexpected EOF from
+the peer. This will be properly reported as B<SSL_ERROR_SSL> with reason
+code B<SSL_R_UNEXPECTED_EOF_WHILE_READING> in the OpenSSL 3.0 release because
+it is truly a TLS protocol error to terminate the connection without
+a SSL_shutdown().
+
+The issue is kept unfixed in OpenSSL 1.1.1 releases because many applications
+which choose to ignore this protocol error depend on the existing way of
+reporting the error.
