Exim version 4.98
-----------------
+JH/01 Use fewer forks & execs for sending many messages to a single host.
+ By passing back more info from the transport to the delivery process,
+ we can loop there. A two-phase queue run will benefit, particularly for
+ mailinglist and smarthost cases.
+
+JH/02 Add transaction support for hintsdbs. The providers supported are tdb and
+ sqlite. Transactions are used for the wait-transport and retry DBs.
+ They imply locking internal to the DB. We no longer need a separate
+ lockfile, can keep the DB handle open for extended periods, yet
+ potentially benefit from concurrency on non-conflicting record uses.
+
+JH/03 With dkim_verify_minimal, avoid calling the DKIM ACL after the first
+ good verify.
+
+JH/04 Remove the docs and support scripts dealing with conversion of Exim
+ version 3 installations.
+
+JH/05 Fix hintsdb support for dbmjz when compiled using sqlite3. Previously
+ the backend support assumed keys would be simple C strings, but dbmjz
+ uses keys with embedded NUL bytes. The builtin hintsdb use is unaffected,
+ but installations using dbmjz will need to rebuild those DBs.
+
+JH/06 Bug 1141: When operating a continued-connection transport, verify that
+ the interface option, if specified, evaluates to match the connection.
+ Previously, a queued message for the same host was sent without checking.
+
+JH/07 Bug 3106: Fix coding in SPA authenticator. A macro argument was not
+ properly parenthesized, resulting in a logic error. While the simple
+ fix was provided by Andrew Aitchison, the over-large code block resulting
+ from this macro made me want to replace it with a real function so more
+ extensive rework becamse needed.
+
+JH/08 The output of "exim -bV" now includes lookup types built as dynamic-load
+ modules.

JH/01 Support list of dkim results in the dkim_status ACL condition, making
it more usable in the data ACL.
loggging reception and sending the SMTP ack. Previously we only flushed
the stdio buffer so there was still the possibility of a disk error.

there is only one) the terminating newline was part of the logged
information.

JH/17 Bug 3064: Fix combination of "-q<period> -R <recipients>". Introduction of
- the multiple-queue-runners facility for 4.97 broking this, giving only
- a one-time run of the queue.
+ 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 vriable
+ 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.
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. 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.
+
+JH/30 Bug 3029: Avoid feeding Resent-From: to DMARC.
+
+JH/31 Bug 3027: For -bh / -bhc tests change to using the compressed form of
+ ipv6 addresses for the sender. Previously the uncompressed form was used,
+ and if used in textual form this would result in behavior difference
+ versus non-bh.
+
+JH/32 Bug 3096: MAIL before HELO/EHLO, where required by hosts_require_helo, is
+ now classed as a protocol error and subject to smtp_max_synprot_errors.
+
+JH/33 Bug 2994: A subdir dsearch lookup should permit a directory name that starts
+ ".." and has following characters.
+
+JH/34 Fix delivery ordering for 2-phase queue run combined with
+ queue_run_in_order.
+
+JH/35 Bug 3099: fix parsing of MIME filename= split over multiple paramemters.
+ Previously the $mime_filename variable would have an incorrect value.
+ While in the code, extend coverage to name= which previously was only
+ supported for single parameters, despite also filling in $mime_filename.
