 Change log file for Exim from version 4.21
 -------------------------------------------

     since this list is usually IP addresses). A host name is now passed as
     "[x.x.x.x]".
 
+24. Changed the calls that set up the SIGCHLD handler in the daemon to use the
+    code that specifies a non-restarting handler (typically sigaction() in
+    modern systems) in an attempt to fix a rare and obscure crash bug.
+
+25. Narrowed the window for a race in the daemon that could cause it to ignore
+    SIGCHLD signals. This is not a major problem, because they are used only to
+    wake it up if nothing else does.
+
+26. A malformed maildirsize file could cause Exim to calculate negative values
+    for the mailbox size or file count. Odd effects could occur as a result.
+    The maildirsize information is now recalculated if the size or filecount
+    end up negative.
+
+27. Added HAVE_SYS_STATVFS_H to the os.h file for Linux, as it has had this
+    support for a long time. Removed HAVE_SYS_VFS_H.
+
+28. Installed the latest version of exipick from John Jetmore.
+
+29. In an address list, if the pattern was not a regular expression, an empty
+    subject address (from a bounce message) matched only if the pattern was an
+    empty string. Non-empty patterns were not even tested. This was the wrong
+    because it is perfectly reasonable to use an empty address as part of a
+    database query. An empty address is now tested by patterns that are
+    lookups. However, all the other forms of pattern expect the subject to
+    contain a local part and a domain, and therefore, for them, an empty
+    address still always fails if the pattern is not itself empty.
+
+30. Exim went into a mad DNS loop when attempting to do a callout where the
+    host was specified on an smtp transport, and looking it up yielded more
+    than one IP address.
+
+31. Re-factored the code for checking spool and log partition space into a
+    function that finds that data and another that does the check. The former
+    is then used to implement four new variables: $spool_space, $log_space,
+    $spool_inodes, and $log_inodes.
+
+32. The RFC2047 encoding function was originally intended for short strings
+    such as real names; it was not keeping to the 75-character limit for
+    encoded words that the RFC imposes. It now respects the limit, and
+    generates multiple encoded words if necessary. To be on the safe side, I
+    have increased the buffer size for the ${rfc2047: expansion operator from
+    1024 to 2048 bytes.
+
+33. It is now permitted to omit both strings after an "if" condition; if the
+    condition is true, the result is "true". As before, when the second string
+    is omitted, a false condition yields an empty string. This makes it less
+    cumbersome to write custom ACL and router conditions.
+
+34. Failure to deliver a bounce message always caused it to be frozen, even if
+    there was an errors_to setting on the router. The errors_to setting is now
+    respected.
+
+35. If an IPv6 address is given for -bh or -bhc, it is now converted to the
+    canonical form (fully expanded) before being placed in
+    $sender_host_address.
+
+36. The table in the code that translates DNS record types into text (T_A to
+    "A" for instance) was missing entries for NS and CNAME. It is just possible
+    that this could have caused confusion if both these types were looked up
+    for the same domain, because the text type is used as part of Exim's
+    per-process caching. But the chance of anyone hitting this buglet seems
+    very small.
+
+37. The dnsdb lookup has a new type, "zns", which walks up the domain tree
+    until it finds some nameserver records. It should be used with care.
