that might affect a running system.
+Exim version 4.78
+-----------------
+
+ * The value of $tls_peerdn is now print-escaped when written to the spool file
+ in a -tls_peerdn line, and unescaped when read back in. We received reports
+ of values with embedded newlines, which caused spool file corruption.
+
+ If you have a corrupt spool file and you wish to recover the contents after
+ upgrading, then lock the message, replace the new-lines that should be part
+ of the -tls_peerdn line with the two-character sequence \n and then unlock
+ the message. No tool has been provided as we believe this is a rare
+ occurence.
+
+ * With OpenSSL 1.0.1+, Exim now supports TLS 1.1 and TLS 1.2. If built
+ against 1.0.1a then you will get a warning message and the
+ "openssl_options" value will not parse "no_tlsv1_1": the value changes
+ incompatibly between 1.0.1a and 1.0.1b, because the value chosen for 1.0.1a
+ is infelicitous. We advise avoiding 1.0.1a.
+
+ "openssl_options" gains "no_tlsv1_1", "no_tlsv1_2" and "no_compression".
+
+
+
+Exim version 4.77
+-----------------
+
+ * GnuTLS will now attempt to use TLS 1.2 and TLS 1.1 before TLS 1.0 and SSL3,
+ if supported by your GnuTLS library. Use the existing
+ "gnutls_require_protocols" option to downgrade this if that will be a
+ problem. Prior to this release, supported values were "TLS1" and "SSL3",
+ so you should be able to update configuration prior to update.
+
+ * The match_<type>{string1}{string2} expansion conditions no longer subject
+ string2 to string expansion, unless Exim was built with the new
+ "EXPAND_LISTMATCH_RHS" option. Too many people have inadvertently created
+ insecure configurations that way. If you need the functionality and turn on
+ that build option, please let the developers know, and know why, so we can
+ try to provide a safer mechanism for you.
+
+ The match{}{} expansion condition (for regular expressions) is NOT affected.
+ For match_<type>{s1}{s2}, all list functionality is unchanged. The only
+ change is that a '$' appearing in s2 will not trigger expansion, but instead
+ will be treated as a literal $ sign; the effect is very similar to having
+ wrapped s2 with \N...\N. If s2 contains a named list and the list definition
+ uses $expansions then those _will_ be processed as normal. It is only the
+ point at which s2 is read where expansion is inhibited.
+
+ If you are trying to test if two email addresses are equal, use eqi{s1}{s2}.
+ If you are testing if the address in s1 occurs in the list of items given
+ in s2, either use the new inlisti{s1}{s2} condition (added in 4.77) or use
+ the pre-existing forany{s2}{eqi{$item}{s1}} condition.
+

Exim version 4.74
-----------------
* Exim will no longer accept a configuration file owned by the Exim
run-time user, unless that account is explicitly the value in
CONFIGURE_OWNER, which we discourage. Exim now checks to ensure that
- files are not writable by other accounts.
+ files are not writeable by other accounts.
* The ALT_CONFIG_ROOT_ONLY build option is no longer optional and is forced
on; the Exim user can, by default, no longer use -C/-D and retain privilege.
2. Up to version 4.69, Exim came with an embedded version of the PCRE library.
As of 4.70, this is no longer the case. To compile Exim, you will need PCRE
-installed. Most OS distributions have ready-made library and develoment
+installed. Most OS distributions have ready-made library and development
packages.
