+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.

+
+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.  This makes the parsing that
+      exinext does more reliable.
+
+JH/29 Bug 3087: Fix SRS encode.  A zero-length quoted element in the local-part
+      would cause a crash.
