+Exim version 4.52
+-----------------
+
+TF/01 Added support for Client SMTP Authorization. See NewStuff for details.
+
+PH/01 When a transport filter timed out in a pipe delivery, and the pipe
+ command itself ended in error, the underlying message about the transport
+ filter timeout was being overwritten with the pipe command error. Now the
+ underlying error message should be appended to the second error message.
+
+TK/01 Fix poll() being unavailable on Mac OSX 10.2.
+
+PH/02 Reduce the amount of output that "make" produces by default. Full output
+ can still be requested.
+
+PH/03 The warning log line about a condition test deferring for a "warn" verb
+ was being output only once per connection, rather than after each
+ occurrence (because it was using the same function as for successful
+ "warn" verbs). This seems wrong, so I have changed it.
+
+TF/02 Two buglets in acl.c which caused Exim to read a few bytes of memory that
+ it should not have, which might have caused a crash in the right
+ circumstances, but probably never did.
+
+PH/04 Installed a modified version of Tony Finch's patch to make submission
+ mode fix the return path as well as the Sender: header line, and to
+ add a /name= option so that you can make the user's friendly name appear
+ in the header line.
+
+TF/03 Added the control = fakedefer ACL modifier.
+
+TF/04 Added the ratelimit ACL condition. See NewStuff for details. Thanks to
+ Mark Lowes for thorough testing.
+
+TK/02 Rewrote SPF support to work with libspf2 versions >1.2.0.
+
+TK/03 Merged latest SRS patch from Miles Wilton.
+
+PH/05 There's a shambles in IRIX6 - it defines EX_OK in unistd.h which conflicts
+ with the definition in sysexits.h (which is #included earlier).
+ Fortunately, Exim does not actually use EX_OK. The code used to try to
+ preserve the sysexits.h value, by assumimg that macro definitions were
+ scanned for macro replacements. I have been disabused of this notion,
+ so now the code just undefines EX_OK before #including unistd.h.
+
+PH/06 There is a timeout for writing blocks of data, set by, e.g. data_timeout
+ in the smtp transport. When a block could not be written in a single
+ write() function, the timeout was being re-applied to each part-write.
+ This seems wrong - if the receiver was accepting one byte at a time it
+ would take for ever. The timeout is now adjusted when this happens. It
+ doesn't have to be particularly precise.
+
+TK/04 Added simple SPF lookup method in EXPERIMENTAL_SPF. See NewStuff for
+ details. Thanks to Chris Webb <chris@arachsys.com> for the patch!
+
+PH/07 Added "fullpostmaster" verify option, which does a check to <postmaster>
+ without a domain if the check to <postmaster@domain> fails.
+
+SC/01 Eximstats: added -xls and the ability to specify output files
+ (patch written by Frank Heydlauf).
+
+SC/02 Eximstats: use FileHandles for outputing results.
+
+SC/03 Eximstats: allow any combination of xls, txt, and html output.
+
+SC/04 Eximstats: fixed display of large numbers with -nvr option
+
+SC/05 Eximstats: fixed merging of reports with empty tables.
+
+SC/06 Eximstats: added the -include_original_destination flag
+
+SC/07 Eximstats: removed tabs and trailing whitespace.
+
+TK/05 Malware: Improve on aveserver error handling. Patch from Alex Miller.
+
+TK/06 MBOX spool code: Add real "From " MBOX separator line
+ so the .eml file is really in mbox format (even though
+ most programs do not really care). Patch from Alex Miller.
+
+TK/07 MBOX spool code: Add X-Envelope-From: and X-Envelope-To: headers.
+ The latter is generated from $received_to and is only set if the
+ message has one envelope recipient. SA can use these headers,
+ obviously out-of-the-box. Patch from Alex Miller.
+
+PH/08 The ${def test on a variable was returning false if the variable's
+ value was "0", contrary to what the specification has always said!
+ The result should be true unless the variable is empty.
+
+PH/09 The syntax error of a character other than { following "${if
+ def:variable_name" (after optional whitespace) was not being diagnosed.
+ An expansion such as ${if def:sender_ident:{xxx}{yyy}} in which an
+ accidental colon was present, for example, could give incorrect results.
+
+PH/10 Tidied the code in a number of places where the st_size field of a stat()
+ result is used (not including appendfile, where other changes are about
+ to be made).
+
+PH/11 Upgraded appendfile so that quotas larger than 2G are now supported.
+ This involved changing a lot of size variables from int to off_t. It
+ should work with maildirs and everything.
+
+TK/08 Apply fix provided by Michael Haardt to prevent deadlock in case of
+ spamd dying while we are connected to it.
+
+TF/05 Fixed a ${extract error message typo reported by Jeremy Harris
+ <jgh@wizmail.org>
+
+PH/12 Applied Alex Kiernan's patch for the API change for the error callback
+ function for BDB 4.3.
+
+PH/13 Changed auto_thaw such that it does not apply to bounce messages.
+
+PH/14 Imported PCRE 6.0; this was more than just a trivial operation because
+ the sources for PCRE have been re-arranged and more files are now
+ involved.
+
+PH/15 The code I had for printing potentially long long variables in PH/11
+ above was not the best (it lost precision). The length of off_t variables
+ is now inspected at build time, and an appropriate printing format (%ld
+ or %lld) is chosen and #defined by OFF_T_FMT. We also define LONGLONG_T
+ to be "long long int" or "long int". This is needed for the internal
+ formatting function string_vformat().
+
+PH/16 Applied Matthew Newton's patch to exicyclog: "If log_file_path is set in
+ the configuration file to be ":syslog", then the script "guesses" where
+ the logs files are, rather than using the compiled in default. In our
+ case the guess is not the same as the compiled default, so the script
+ suddenly stopped working when I started to use syslog. The patch checks
+ to see if log_file_path is "". If so, it attempts to read it from exim
+ with no configuration file to get the compiled in version, before it
+ falls back to the previous guessing code."
+
+TK/09 Added "prvs" and "prvscheck" expansion items. These help a lot with
+ implementing BATV in an Exim configuration. See NewStuff for the gory
+ details.
+
+PH/17 Applied Michael Haardt's patch for HP-UX, affecting only the os.h and
+ Makefile that are specific to HP-UX.
+
+PH/18 If the "use_postmaster" option was set for a recipient callout together
+ with the "random" option, the postmaster address was used as the MAIL
+ FROM address for the random test, but not for the subsequent recipient
+ test. It is now used for both.
+
+PH/19 Applied Michael Haardt's patch to update Sieve to RFC3028bis. "The
+ patch removes a few documentation additions to RFC 3028, because the
+ latest draft now contains them. It adds the new en;ascii-case comparator
+ and a new error check for 8bit text in MIME parts. Comparator and
+ require names are now matched exactly. I enabled the subaddress
+ extension, but it is not well tested yet (read: it works for me)."
+
+PH/20 Added macros for time_t as for off_t (see PH/15 above) and used them to
+ rework some of the code of TK/09 above to avoid the hardwired use of
+ "%lld" and "long long". Replaced the call to snprintf() with a call to
+ string_vformat().
+
+PH/21 Added another message to those in 4.51/PH/42, namely "All relevant MX
+ records point to non-existent hosts".
+
+PH/22 Fixed some oversights/typos causing bugs when Exim is compiled with
+ experimental DomainKeys support:
+
+ (1) The filter variables $n0-$n9 and $sn0-$sn9 were broken.
+ (2) On an error such as an illegally used "control", the wrong name for
+ the control was given.
+
+ These problems did NOT occur unless DomainKeys support was compiled.
