+Exim version 4.61
+-----------------
+
+1. The default number of ACL variables of each type has been increased to 20,
+and it's possible to compile Exim with more. You can safely upgrade to this
+release if you already have messages on the queue with saved ACL variable
+values. However, if you downgrade from this release with messages on the queue,
+any saved ACL values they may have will be lost.
+
+2. The default value for rfc1413_query_timeout has been changed from 30s to 5s.
+
+
+Exim version 4.54
+-----------------
+
+There was a problem with 4.52/TF/02 in that a "name=" option on control=
+submission terminated at the next slash, thereby not allowing for slashes in
+the name. This has been changed so that "name=" takes the rest of the string as
+its data. It must therefore be the last option.
+
+
+Version 4.53
+------------
+
+If you are using the experimental Domain Keys support, you must upgrade to
+at least libdomainkeys 0.67 in order to run this release of Exim.
+
+
+Version 4.51
+------------
+
+1. The format in which GnuTLS parameters are cached (in the file gnutls-params
+in the spool directory) has been changed. The new format can also be generated
+externally, so it is now possible to update the values from outside Exim. This
+has been implemented in an upwards, BUT NOT downwards, compatible manner.
+Upgrading should be seamless: when Exim finds that it cannot understand an
+existing cache file, it generates new parameters and writes them to the cache
+in the new format. If, however, you downgrade from 4.51 to a previous release,
+you MUST delete the gnutls-params file in the spool directory, because the
+older Exim will not recognize the new format.
+
+2. When doing a callout as part of verifying an address, Exim was not paying
+attention to any local part prefix or suffix that was matched by the router
+that accepted the address. It now behaves in the same way as it does for
+delivery: the affixes are removed from the local part unless
+rcpt_include_affixes is set on the transport. If you have a configuration that
+uses prefixes or suffixes on addresses that could be used for callouts, and you
+want the affixes to be retained, you must make sure that rcpt_include_affixes
+is set on the transport.
+
+3. Bounce and delay warning messages no longer contain details of delivery
+errors, except for explicit messages (e.g. generated by :fail:) and SMTP
+responses from remote hosts.
+

 Version 4.50
 ------------
 
-The exicyclog script has been updated to use three-digit numbers in rotated log 
-files if the maximum number to keep is greater than 99. If you are already 
-keeping more than 99, there will be an incompatible change when you upgrade. 
-You will probably want to rename your old log files to the new form before 
-running the new exicyclog. The following script, by Mick Swisher, can do this 
-for you:
-
-# Begin conversion
-# Rename all the old files by adding additional leading zeros.
-count=99
-while [ $count -gt 0 ]; do
-if [ $count -lt 100 ]; then newt=0$count; oldt=$count; fi
-if [ $count -lt 10 ]; then newt=00$count; oldt=0$count; fi
-if [ -f $mainlog.$oldt ]; then
-  $mv $mainlog.$oldt $mainlog.$newt
-elif [ -f $mainlog.$oldt.$suffix ]; then
-  $mv $mainlog.$oldt.$suffix $mainlog.$newt.$suffix
-fi
-if [ -f $rejectlog.$oldt ]; then
-  $mv $rejectlog.$oldt $rejectlog.$newt
-elif [ -f $rejectlog.$oldt.$suffix ]; then
-  $mv $rejectlog.$oldt.$suffix $rejectlog.$newt.$suffix
-fi
-count=`expr $count - 1`
