-Change log file for Exim from version 4.21
-------------------------------------------
 This document describes *changes* to previous versions, that might
 affect Exim's operation, with an unchanged configuration file.  For new
 options, and new features, see the NewStuff file next to this ChangeLog.

       an attempt to use a TLS library read routine dereffed a nul pointer,
       causing a segfault.
 
+JH/35 Bug 2409: filter out-of-spec chars from callout response before using
+      them in our smtp response.
+
+JH/36 Have the general router option retry_use_local_part default to true when
+      any of the restrictive preconditions are set (to anything).  Previously it
+      was only for check_local user.  The change removes one item of manual
+      configuration which is required for proper retries when a remote router
+      handles a subset of addresses for a domain.
+
+JH/37 Appendfile: when evaluating quota use (non-quota_size_regex) take the file
+      link count into consideration.
+
+HS/04 Fix handling of very log lines in -H files. If a -<key> <value> line
+      caused the extension of big_buffer, the following lines were ignored.
+
+JH/38 Bug 1395: Teach the DNS negative-cache about TTL value from the SOA in
+      accordance with RFC 2308.  Previously there was no expiry, so a longlived
+      receive process (eg. due to ACL delays) versus a short SOA value could
+      surprise.
+
+HS/05 Handle trailing backslash gracefully. (CVE-2019-15846)
+
+JH/39 Promote DMARC support to mainline.
+
+JH/40 Bug 2452: Add a References: header to DSNs.
+
+JH/41 With GnuTLS 3.6.0 (and later) do not attempt to manage Diffie-Hellman
+      parameters.  The relevant library call is documented as "Deprecated: This
+      function is unnecessary and discouraged on GnuTLS 3.6.0 or later. Since
+      3.6.0, DH parameters are negotiated following RFC7919."
+
+HS/06 Change the default of dnssec_request_domains to "*"
+
+JH/42 Bug 2545: Fix CHUNKING for all RCPT commands rejected.  Previously we
+      carried on and emitted a BDAT command, even when PIPELINING was not
+      active.
+
+JH/43 Bug 2465: Fix taint-handling in dsearch lookup.  Previously a nontainted
+      buffer was used for the filename, resulting in a trap when tainted
+      arguments (eg. $domain) were used.
+
+JH/44 With OpenSSL 1.1.1 (onwards) disable renegotiation for TLS1.2 and below;
+      recommended to avoid a possible server-load attack.  The feature can be
+      re-enabled via the openssl_options main cofiguration option.
+
+JH/45 local_scan API: documented the current smtp_printf() call. This changed
+      for version 4.90 - adding a "more data" boolean to the arguments.
+      Bumped the ABI version number also, this having been missed previously;
+      release versions 4.90 to 4.92.3 inclusive were effectively broken in
+      respect of usage of smtp_printf() by either local_scan code or libraries
+      accessed via the ${dlfunc } expansion item.  Both will need coding
+      adjustment for any calls to smtp_printf() to match the new function
+      signature; a FALSE value for the new argument is always safe.
+
+JH/46 FreeBSD: fix use of the sendfile() syscall.  The shim was not updating
+      the file-offset (which the Linux syscall does, and exim expects); this
+      resulted in an indefinite loop.
+
+JH/47 ARC: fix crash in signing, triggered when a configuration error failed
+      to do ARC verification.  The Authentication-Results: header line added
+      by the configuration then had no ARC item.
