Previously one was only + written if there were rewrite rules. + +JH/16 Two-phase queue runs are now reported in the daemon startup log line and + in exiwhat output. + +JH/17 Bug 3064: Fix combination of "-q -R ". Introduction of + the multiple-queue-runners facility for 4.97 broke this, giving only a + one-time run of the queue. + +JH/18 Bug 3068: Log a warning for use of deprecated syntax in query-style + lookups. + +JH/19 Fix TLS startup. When the last expansion done before the initiation of a + TLS session resulted in a forced-fail, a misleading error was logged for + the expansino of tls_certificates. This would affect the common case of + that option being set (main-section options) but not having any variable + parts. It could also potentially affect tls_privatekeys. The underlyding + coding errors go back to 4.90 but were only exposed in 4.97. + +JH/20 Bug 3047: A recent (somewhere between 10.34 and 10.42) version of the + pcre2 library starting allocating 20kB rather than 112 bytes per match + call, which broke the 2GB total limitation on Exim's memory management + when a user had over 104207 messages stored and the appendfile + maildir_quota_directory_regex option is in use. Release the allocated + memory every thosand files to avoid this. + The same issue arises with the ACL regex condition, which is applied + to every line of a received message. + +JH/21 Bug 3059: Fix crash in smtp transport. When running for a message for + which all recipients had been handled (itself an issue) a null-pointer + deref was done on trying to write a retry record. Fix that by counting + the outstanding recipients before trying to transmit the message. + The situation arose for a second MX try within a transport run, when the + first had perm-rejected a recipient (the only one for the connection, in + the case seen) during pipelining, and then closed the TCP connection. + The transport classified that as an I/O error, leaving the message + outstanding but having marked up the recipient as dealt-with. It then + tried another MX because of the I/O error. Fix this by converting the + message-level status to ok if there was a close but all recipients were + dealt with. Thanks to Wolfgand Breyha for debug runs. + +JH/22 The ESMTP_LIMITS facility (RFC 9422) is promoted from experimental status + and is now controlled by the build-time option DISABLE_ESMTP_LIMITS. + +JH/23 Bug 3066: Avoid leaking lookup database credentials to log. + +JH/24 Bug 3081: Fix a delivery process crash. When the router "errors_to" + option specified a fixed address, later rewriting on that address would + trip on the configuration data being readonly. Instead of modifying + in-place, copy data. Found and fixed by Peter Benie. + +JH/25 Bug 3079: Fix crash in dbmnz. When a key was present for zero-length + data a null pointer was followed. Find and testcase by Sebastian Bugge. + +JH/26 Fix encoding for an AUTH parameter on a MAIL FROM command. Previously + decimal 127 chars were not encoded, and lowercase hex was used for + encoded values. Outstanding since at least 1999. + +JH/27 Fix crash in logging. When a message with a large number of recipients + had been received, and logging of recipients is enabled, the buffer used + for logging could reach limit. A read using a null pointer would then + be done, resulting in a crash of the receiving process before an SMTP + ACK for the message was returned to the sending system. Duplicate + messages were created as a result. + Find and debug help by Mateusz Krawczyk + +JH/28 Bug 3086: Fix exinext for ipv6. Change the format of keys in the retry + DB, wrapping transport record bare-ip "host names" and ipv6 + "host addresses" in square-brackets.
