+-----------------
+
+Various length limits have been applied to Exim's parsing of its command-line.
+These are all set to be at least as long as any valid input, so we do not believe
+that any real use-cases have been affected by this.
+
+The names of various drivers (authenticators, routers, transports, ...) have
+always been limited to 64 characters, but before this release the names were
+silently truncated, inviting problems.  Now the length limit should be enforced.
+If this affects you, then please rename to use shorter names.
+
+The default maximum number of recipients of a single email has changed from
+"unlimited" (ie: as much as CPU and memory will allow, until something breaks
+badly) to 50,000.  You can raise or lower this as you see fit, but we strongly
+caution against using zero/unlimited.

+Attempting to remove, in router or transport, a header name that ends with
+an asterisk (which is a standards-legal name) will now result in all headers
+named starting with the string before the asterisk being removed.  We recommend
+staying away from such names, if they are private ones (and in case of future
+enhancements, alao header names that look like REs).
