+
+
+Exim version 4.89
+-------------------
+
+JH/01 Bug 1922: Support IDNA2008. This has slightly different conversion rules
+ than -2003 did; needs libidn2 in addition to libidn.
+
+JH/02 The path option on a pipe transport is now expanded before use.
+
+PP/01 GitHub PR 50: Do not call ldap_start_tls_s on ldapi:// connections.
+ Patch provided by "Björn", documentation fix added too.
+
+JH/03 Bug 2003: fix Proxy Protocol v2 handling: the address size field was
+ missing a wire-to-host endian conversion.
+
+JH/04 Bug 2004: fix CHUNKING in non-PIPELINEING mode. Chunk data following
+ close after a BDAT command line could be taken as a following command,
+ giving a synch failure. Fix by only checking for synch immediately
+ before acknowledging the chunk.
+
+PP/02 GitHub PR 52: many spelling fixes, which include fixing parsing of
+ no_require_dnssec option and creation of _HAVE_TRANSPORT_APPEND_MAILDIR
+ macro. Patches provided by Josh Soref.
+
+JH/05 Bug 2017: Fix DKIM verification in -bh test mode. The data feed into
+ the dkim code may be unix-mode line endings rather than smtp wire-format
+ CRLF, so prepend a CR to any bare LF.
+
+JH/06 Rationalise the coding for callout smtp conversations and transport ones.
+ As a side-benfit, callouts can now use PIPELINING hence fewer round-trips.
