that might affect a running system.
+Exim version 4.95
+-----------------
+
+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.
+
+
+Exim version 4.94
+-----------------
+
+Some Transports now refuse to use tainted data in constructing their delivery
+location; this WILL BREAK configurations which are not updated accordingly.
+In particular: any Transport use of $local_part which has been relying upon
+check_local_user far away in the Router to make it safe, should be updated to
+replace $local_part with $local_part_data.
+
+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).
+
+
+Exim version 4.93
+-----------------
+
+For a detailed list of changes that might affect Exim's operation with
+an unchanged configuration, please see the doc/ChangeLog file.
+
+Build:
+
+ * SUPPORT_DMARC replaces EXPERIMENTAL_DMARC
+
+ * DISABLE_TLS replaces SUPPORT_TLS
+
+ * Bump the version for the local_scan API.
+
+Runtime:
+
+ * smtp transport option hosts_try_fastopen defaults to "*".
+
+ * DNSSec is requested (not required) for all queries. (This seemes to
+ ask for trouble if your resolver is a systemd-resolved.)
+
+ * Generic router option retry_use_local_part defaults to "true" under specific
+ pre-conditions.
+
+ * Introduce a tainting mechanism for values read from untrusted sources.
+
+ * Use longer file names for temporary spool files (this avoids
+ name conflicts with spool on a shared file system).
+
+ * Use dsn_from main config option (was ignored previously).
+
+
+Exim version 4.92
+-----------------
+
+ * Exim used to manually follow CNAME chains, to a limited depth. In this
+ day-and-age we expect the resolver to be doing this for us, so the loop
+ is limited to one retry unless the (new) config option dns_cname_loops
+ is changed.
+
+Exim version 4.91
+-----------------
+
+ * DANE and SPF have been promoted from Experimental to Supported status, thus
+ the options to enable them in Local/Makefile have been renamed.
+ See current src/EDITME for full details, including changes in dependencies,
+ but loosely: replace EXPERIMENTAL_SPF with SUPPORT_SPF and replace
+ EXPERIMENTAL_DANE with SUPPORT_DANE.
+
+ * Ancient ClamAV stream support, long deprecated by ClamAV, has been removed;
+ if you were building with WITH_OLD_CLAMAV_STREAM enabled then your problems
+ have marginally increased.
+
+ * A number of logging changes; if relying upon the previous DKIM additional
+ log-line, explicit log_selector configuration is needed to keep it.
+
+ * Other incompatible changes in EXPERIMENTAL_* features, read NewStuff and
+ ChangeLog carefully if relying upon an experimental feature such as DMARC.
+ Note that this includes changes to SPF as it was promoted into Supported.

2. Up to version 4.69, Exim came with an embedded version of the PCRE library.
As of 4.70, this is no longer the case. To compile Exim, you will need PCRE
