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 ------------ @@ -35,27 +90,7 @@ 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.
