+PH/09 Quota values can be followed by G as well as K and M.
+
+PH/10 $message_linecount is a new variable that contains the total number of
+      lines in the header and body of the message. Compare $body_linecount,
+      which is the count for the body only. During the DATA and
+      content-scanning ACLs, $message_linecount contains the number of lines
+      received. Before delivery happens (that is, before filters, routers, and
+      transports run) the count is increased to include the Received: header
+      line that Exim standardly adds, and also any other header lines that are
+      added by ACLs. The blank line that separates the message header from the
+      body is not counted. Here is an example of the use of this variable in a
+      DATA ACL:
+
+        deny message   = Too many lines in message header
+             condition = \
+               ${if <{250}{${eval: $message_linecount - $body_linecount}}}
+
+      In the MAIL and RCPT ACLs, the value is zero because at that stage the
+      message has not yet been received.
+
+PH/11 In a ${run expansion, the variable $value (which contains the standard
+      output) is now also usable in the "else" string.
+
+PH/12 In a pipe transport, although a timeout while waiting for the pipe
+      process to complete was treated as a delivery failure, a timeout while
+      writing the message to the pipe was logged, but erroneously treated as a
+      successful delivery. Such timeouts include transport filter timeouts. For
+      consistency with the overall process timeout, these timeouts are now
+      treated as errors, giving rise to delivery failures by default. However,
+      there is now a new Boolean option for the pipe transport called
+      timeout_defer, which, if set TRUE, converts the failures into defers for
+      both kinds of timeout. A transport filter timeout is now identified in
+      the log output.
