This file contains descriptions of new features that have been added to Exim.

+Version 4.90
+------------
+
+ 1. PKG_CONFIG_PATH can now be set in Local/Makefile;
+ wildcards will be expanded, values are collapsed.
+
+ 2. The ${readsocket } expansion now takes an option to not shutdown the
+ connection after sending the query string. The default remains to do so.
+
+ 3. An smtp transport option "hosts_noproxy_tls" to control whether multiple
+ deliveries on a single TCP connection can maintain a TLS connection
+ open. By default disabled for all hosts, doing so saves the cost of
+ making new TLS sessions, at the cost of having to proxy the data via
+ another process. Logging is also affected.
+
+ 4. A malware connection type for the FPSCAND protocol.
+
+ 5. An option for recipient verify callouts to hold the connection open for
+ further recipients and for delivery.
+
+ 6. The reproducible build $SOURCE_DATE_EPOCH environment variable is now
+ supported.
+
+ 7. Optionally, an alternate format for spool data-files which matches the
+ wire format - meaning more efficient reception and transmission (at the
+ cost of difficulty with standard Unix tools). Only used for messages
+ received using the ESMTP CHUNKING option, and when a new main-section
+ option "spool_wireformat" (false by default) is set.
+
+ 8. New main configuration option "commandline_checks_require_admin" to
+ restrict who can use various introspection options.
+
+
+Version 4.89
+------------
+
+ 1. Allow relative config file names for ".include"
+
+ 2. A main-section config option "debug_store" to control the checks on
+ variable locations during store-reset. Normally false but can be enabled
+ when a memory corrution issue is suspected on a production system.
+
+
Version 4.88
------------
10. Feature macros, generated from compile options. All start with "_HAVE_"
and go on with some roughly recognisable name. Driver macros, for
- router, transport and authentication drivers; names starting with "_DRVR_".
+ router, transport and authentication drivers; names starting with "_DRIVER_".
Option macros, for each configuration-file option; all start with "_OPT_".
Use the "-bP macros" command-line option to see what is present.
12. OCSP stapling is now supported by default.
13. If built with the EXPERIMENTAL_DSN feature enabled, Exim will output
- Delivery Status Notification messages in MIME format, and negociate
+ Delivery Status Notification messages in MIME format, and negotiate
DSN features per RFC 3461.
ignored.
7. New cutthrough routing feature. Requested by a "control = cutthrough_delivery"
- ACL modifier; works for single-recipient mails which are recieved on and
+ ACL modifier; works for single-recipient mails which are received on and
deliverable via SMTP. Using the connection made for a recipient verify,
if requested before the verify, or a new one made for the purpose while
the inbound connection is still active. The bulk of the mail item is copied
direct from the inbound socket to the outbound (as well as the spool file).
When the source notifies the end of data, the data acceptance by the destination
- is negociated before the acceptance is sent to the source. If the destination
+ is negotiated before the acceptance is sent to the source. If the destination
does not accept the mail item, for example due to content-scanning, the item
is not accepted from the source and therefore there is no need to generate
a bounce mail. This is of benefit when providing a secondary-MX service.
The downside is that delays are under the control of the ultimate destination
system not your own.
- The Recieved-by: header on items delivered by cutthrough is generated
+ The Received-by: header on items delivered by cutthrough is generated
early in reception rather than at the end; this will affect any timestamp
included. The log line showing delivery is recorded before that showing
reception; it uses a new ">>" tag instead of "=>".
provided to the authentication method which failed. It is available
for use in subsequent ACL processing (typically quit or notquit ACLs).
