that might affect a running system.

+-----------------
+
+ * The value of $tls_peerdn is now print-escaped when written to the spool file
+ in a -tls_peerdn line, and unescaped when read back in. We received reports
+ of values with embedded newlines, which caused spool file corruption.
+
+ If you have a corrupt spool file and you wish to recover the contents after
+ upgrading, then lock the message, replace the new-lines that should be part
+ of the -tls_peerdn line with the two-character sequence \n and then unlock
+ the message. No tool has been provided as we believe this is a rare
+ occurence.
+
+ * With OpenSSL 1.0.1+, Exim now supports TLS 1.1 and TLS 1.2. If built
+ against 1.0.1a then you will get a warning message and the
+ "openssl_options" value will not parse "no_tlsv1_1": the value changes
+ incompatibly between 1.0.1a and 1.0.1b, because the value chosen for 1.0.1a
+ is infelicitous. We advise avoiding 1.0.1a.
+
+ "openssl_options" gains "no_tlsv1_1", "no_tlsv1_2" and "no_compression".
+
+ * Ldap lookups returning multi-valued attributes now separate the attributes
+ with only a comma, not a comma-space sequence. Also, an actual comma within
+ a returned attribute is doubled. This makes it possible to parse the
+ attribute as a comma-separated list. Note the distinction from multiple
+ attributes being returned, where each one is a name=value pair.
