affect Exim's operation, with an unchanged configuration file. For new
options, and new features, see the NewStuff file next to this ChangeLog.
+Exim version 4.95
+-----------------
+
+JH/01 Move the wait-for-next-tick (needed for unique messmage IDs) from
+ after reception to before a subsequent reception. This should
+ mean slightly faster delivery, and also confirmation of reception
+ to senders.
+
+JH/02 Move from using the pcre library to pcre2. The former is no longer
+ being developed or supported (by the original developer).
+
+JH/03 Constification work in the filters module required a major version
+ bump for the local-scan API. Specifically, the "headers_charset"
+ global which is visible via the API is now const and may therefore
+ not be modified by local-scan code.
+
+JH/04 Fix ClamAV TCP use under FreeBSD. Previously the OS-specific shim for
+ sendfile() didi not account for the way the ClamAV driver code called it.

Exim version 4.95
-----------------
JH/07 Bug 2597: Fix a resource leak. Using a lookup in obtaining a value for
smtp_accept_max_per_host allocated resources which were not released
when the limit was exceeded. This eventually crashed the daemon. Fix
- by adding a relase action in that path.
+ by adding a release action in that path.
JH/08 Bug 2598: Fix verify ACL condition. The options for the condition are
expanded; previously using tainted values was rejected. Fix by using

suspended/resumed. The Linux CLOCK_MONOTONIC does not account for time
- spent suspended, ignoring the Posix definition. Previously we assumed
+ spent suspended, ignoring the POSIX definition. Previously we assumed
it did and a constant offset from real time could be used as a correction.
Change to using the same clock source for the start-of-message and the
post-message next-tick-wait. Also change to using CLOCK_BOOTTIME if it
JH/17 Bug 2295: Fix DKIM signing to always semicolon-terminate. Although the
RFC says it is optional some validators care. The missing char was not
- intended but triggered by a line-wrap alignement. Discovery and fix by
+ intended but triggered by a line-wrap alignment. Discovery and fix by
Guillaume Outters, hacked on by JH.
JH/18 Bug 2617: Fix a taint trap in parse_fix_phrase(). Previously when the
name being quoted was tainted a trap would be taken. Fix by using
- dynamicaly created buffers. The routine could have been called by a
+ dynamically created buffers. The routine could have been called by a
rewrite with the "h" flag, by using the "-F" command-line option, or
by using a "name=" option on a control=submission ACL modifier.
JH/30 Bug 2677: fix matching of long addresses. Since 4.93 a limit of 256 was
applied. This resulted, if any header-line rewrite rules were configured,
- in a panic-log trigerrable by sending a message with a long address in
- a header. Fix by increaing the arbitrary limit to larger than a single

+ a header. Fix by increasing the arbitrary limit to larger than a single
(dewrapped) 5322 header line maximum size.
JH/31 The ESMTP option name advertised for the SUPPORT_EARLY_PIPE build option
is changed from X_PIPE_CONNECT to PIPE_CONNECT. This is in line with
RFC 6648 which deprecates X- options in protocols as a general practice.
Changeover between the implementations is handled by the mechanisms

+ already coded.
JH/32 Bug 2599: fix delay of delivery to a local address where there is also
a remote which uses callout/hold. Previously the local was queued.
JH/38 When logging an AUTH failure, as server, do not include sensitive
information. Previously, the credentials would be included if given
- as part of the AUTH command line and an ACL denied authentidcation.
+ as part of the AUTH command line and an ACL denied authentication.
JH/39 Bug 2691: fix $local_part_data. When the matching list element
referred to a file, bad data was returned. This likely also affected
transport executions. This also mean that the log lines for the
messages can show the proxy information.

+JH/50 Bug 2672: QT elements in log lines, unless disabled, now exclude the
receive time. With modern systems the difference is significant.
The historical behaviour can be restored by disabling (a new) log_selector
"queue_time_exclusive".

- content) were specifically tested for. Now, also cover epxansions

+ content) were specifically tested for. Now, also cover expansions
+ resulting in ACL names and inline ACL content.
JH/52 Fix ${ip6norm:} operator. Previously, any trailing line text was dropped,
making it unusable in complex expressions.
This affects 1.4.1-1 on Fedora 33 (1.3.2-3 is functional); and has
been reported on other platforms.
+JH/55 TLS: as server, reject connections with ALPN indicating non-smtp use.
+
+JH/56 Make the majority of info read from config files readonly, for defence-in-
+ depth against exploits. Suggestion by Qualys.
+ Not supported on Solaris 10.
+
+JH/57 Fix control=fakreject for a custom message containing tainted data.
+ Previously this resulted in a log complaint, due to a re-expansion present
+ since fakereject was originally introduced.
+
+JH/58 GnuTLS: Fix certextract expansion. If a second modifier after a tag
+ modifier was given, a loop resulted.
+
+JH/59 DKIM: Fix small-message verification under TLS with chunking. If a
+ pipelined SMTP command followed the BDAT LAST then it would be
+ incorrectly treated as part of the message body, causing a verification
+ fail.
+
+JH/60 Bug 2805: Fix logging of domain-literals in Message_ID: headers. They
+ require looser validation rules than those for 821-level addresses,
+ which only permit IP addresses.
