-------------------------------------------

+Exim version 4.83
+-----------------
+
+TF/01 Correctly close the server side of TLS when forking for delivery.
+
+ When a message was received over SMTP with TLS, Exim failed to clear up
+ the incoming connection properly after forking off the child process to
+ deliver the message. In some situations the subsequent outgoing
+ delivery connection happened to have the same fd number as the incoming
+ connection previously had. Exim would try to use TLS and fail, logging
+ a "Bad file descriptor" error.
+
+TF/02 Portability fix for building lookup modules on Solaris when the xpg4
+ utilities have not been installed.
+
+JH/01 Fix memory-handling in use of acl as a conditional; avoid free of
+ temporary space as the ACL may create new global variables.
+
+TL/01 LDAP support uses per connection or global context settings, depending
+ upon the detected version of the libraries at build time.
+
+TL/02 Experimental Proxy Protocol support: allows a proxied SMTP connection
+ to extract and use the src ip:port in logging and expansions as if it
+ were a direct connection from the outside internet.
+
+JH/02 Add ${listextract {number}{list}{success}{fail}}.
+
+TL/03 Bugzilla 1433: Fix DMARC SEGV with specific From header contents.
+ Properly escape header and check for NULL return.
