This document contains detailed information about incompatibilities that might
be encountered when upgrading from one release of Exim to another. The
that might affect a running system.
+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`
-done
