+2005-12-16 Stable Version 1.0.4 released
+----------------------------------------
+2005-12-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	Replaced static counter used when generating the default Message-Id
+	header with getpid() to minimise the risk of 2 processes generating
+	the same Message-Id.  If the platform provides gettimeofday() this is
+	used to further reduce the possibility of collision.
+	Thanks to Dmitry Maksyoma <dmaks@esphion.com> for spotting this and
+	suggesting the fix.
+
+      * Makefile.am */Makefile.am
+	Replace CFLAGS with AM_CFLAGS to silence warning from automake.
+	
+      * Makefile.am COPYING COPYING.LIB
+	Fixed the names of the files with the GPL and LGPL.  It seems
+	the LGPL version of COPYING got zapped by autoconf at some time
+	in the past.
+
+2005-08-29	Brian Stafford	<brian@stafford.uklinux.net>
+      * acinclude.m4
+	Fix underquoted definition of ACX_WHICH_GETHOSTBYNAME_R.  Thanks
+	to Matthias Andree <matthias.andree@gmx.de>.
+
+2005-07-25	Brian Stafford	<brian@stafford.uklinux.net>
+      * errors.c
+	Added #ifdefs for some of the EAI_ constants used by getaddrinfo()
+	which are not defined by OSX.
+	Thanks to Thomas Deselaers <deselaers@gmail.com>
+
+2005-07-21	Brian Stafford	<brian@stafford.uklinux.net>
+      * acinclude.m4
+	Fix cross compiling issue when detecting snprintf as suggested by
+	Chris Richards <Chris.Richards@red-m.com>
+
+2005-07-02	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-api.c
+	Plug memory leaks in smtp_destroy_session() and smtp_set_server().
+	Thanks to Bas ten Berge <sam.ten.berge@hccnet.nl> for report and patch.
+	Also reported by Heikki Lindholm <heikki.lindholm@ipnetworks.fi>
+
+2005-02-03 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+	exts was set with the wrong flag (DSN) when checking if CHUNKING
+	is a required extension.
+
+2004-07-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-tls.c
+	Applied OpenSSL patch from Pawel Salek when checking subjectAltName.
+
+2004-04-20 Stable Version 1.0.3 released
+----------------------------------------
+2004-04-20 	Brian Stafford	<brian@stafford.uklinux.net>
+      * memrchr.c configure.in
+	Added memrchr() implementation for systems that don't have one.
+
+      * smtp-tls.c
+	Applied patches from Pawel Salek to check subjectAltName for
+	wildcarded domain name when validating server certificate.
+
+
+2004-01-06 Stable Version 1.0.2 released
+--------------------------------------
+2003-12-01 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-tls.c examples/mail-file.c
+	Applied patch from Pawel Salek.
+
+      * smtp-tls.c
+        Fixed typo in check_file() which prevented it from doing quite
+	the right thing.
+	The domain name check for the server certificate is now implemented
+	using the wildcard match described in RFC 2818.
+	Check_file() and check_directory() return different values for
+	unusable vs absent files.
+
+2003-09-12 Stable Version 1.0.1 released
+--------------------------------------
+2003-09-11 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-auth.c smtp-bdat.c smtp-etrn.c smtp-tls.c
+	More thoroughly check return value from read_smtp_response().
+
+      * libesmtp.h errors.c
+        Added new "Client error" error code.  This is just a cop-out,
+        used when an API called by libesmtp fails.
+
+      * base64.c
+	Make conversions immune to NULL source data,
+
+      * examples/mail-file.c
+	Cleaned up some compiler warnings
+
+2003-09-02 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.[hc]
+	Added a few extra sio_ calls.  Not actually used in libESMTP though.
+
+2003-07-29 	Brian Stafford	<brian@stafford.uklinux.net>
+      * concatenate.c errors.c getaddrinfo.c headers.c htable.c
+      * protocol.c siobuf.c
+	Don't perform zero length operations using the memxxx() functions.
+	This may avoid segfaults on some platforms or libraries.
+
+      * siobuf.c
+        Improved handling of flushes in sio_write() particularly in the
+        case where data would exactly fill remaining space in the buffer.
+
+2003-07-27 	Brian Stafford	<brian@stafford.uklinux.net>
+      * rfc2822date.c
+	Correct leap year compensation for January and February in
+	libesmtp_mktime().
+
+2003-07-27 	Brian Stafford	<brian@stafford.uklinux.net>
+      * examples/Makefile
+	Changed compiler flags from -ansi to -std=c99 and added -W
+
+2003-03-04 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	Eliminated bug where find_header() could pass -1 to the length
+	argument of memchr() causing a core dump on some architectures.
+
+2003-02-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp-private.h protocol.c smtp-bdat.c
+	M$ Exchange does not accept a chunk size of 0 in BDAT 0 LAST as
+	explicitly permitted by RFC 3030, *sigh*.  Hackish workaround
+	implemented.
+
+2003-01-27 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in Makefile.am
+	Added DIST_SUBDIRS macro to make sure tarball gets built properly.
+	This one slipped past 'make distcheck' last time for some reason
+	but then autoconf & friends are totally inscruitable.
+
+      * ntlm/ntlmdes.c
+        OpenSSL 0.9.7 changes some typedefs.  Changed to suit, should
+        still be compatible with previous OpenSSL versions.
+
+2002-11-09 Stable Version 1.0 released
+--------------------------------------
+2002-11-09 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+      	All version 1.0 features enabled by default.
+	--enable-isoc now sets -std=c99 instead of -ansi
+
+      * headers.c
+	Added missing check for NULL pointer in destroy_header_table.
+	Reversed order of freeing header structures and hash table to
+	avoid referencing freed memory. (Wally Yau)
+
+2002-06-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-etrn.c
+	Compilation fails with `./configure --enable-more-warnings=picky
+	--disable-etrn'.  Added missing __attribute__ ((unused)) markers
+	to offending function arguments to avoid this.
+
+2002-06-24 Version 1.0rc1 released
+----------------------------------
+2002-06-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in Makefile.am protocol.c protocol-states.h
+      * smtp-api.c smtp-bdat.c libesmtp.h libesmtp-private.h
+        Added experimental support for the SMTP CHUNKING extension.
+
+      * configure.in
+	Enable non-standard AUTH= response by default.
+
+2002-05-31 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c libesmtp.h libesmtp-private.h
+      	Added API call to permit protocol timeouts to be set.
+
+      * ntlm/ntlmstruct.c
+        Replaced use of byteswap.h and bswap_{16,32} with locally defined
+        functions.
+
+2002-04-24 Version 0.8.12 released
+----------------------------------
+2002-03-14 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	Setting Hdr_PROHIBIT did not work properly.  Thanks to Ronald
+	F. Guilmette for pointing this out.
+
+2002-03-13 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c libesmtp.h configure.in
+      	Revoked deprecated status from smtp_option_require_all_recipients
+      	and remove the corresponding --enable-require-all-recipients
+      	parameter to configure.
+
+2002-03-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp.h libesmtp-private.h protocol.c smtp-tls.c
+      	RFC 2487 is obsoleted by RFC 3207.  Updated references.
+
+      * protocol.c
+      	The check for required STARTTLS was omitted when processing the
+      	HELO command.  If a server did not implement EHLO the session
+      	would proceed instead of quitting.  Check added and the event
+      	callback added to report the missing extension to the
+      	application.
+
+2002-03-06 Version 0.8.11 released
+----------------------------------
+
+2002-03-04 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+        Fix buffer overflow problem in read_smtp_response.  This
+        overflow could be exploited by a malicious SMTP server to
+        overwrite the stack and hence a carefully crafted response could
+        cause arbitrary code to be executed.  Also took the opportunity
+        to add a related check for a potential DoS attack which makes
+        use of excessively long SMTP responses.  Thanks to Colin Phipps
+        for detecting this.
+
+      * concatenate.[ch]
+        New function cat_shrink to shrink-wrap the allocated buffer.
+
+      * libesmtp.h errors.c
+        New unterminated response error code and description.
+
+      * ntlm/ntlmstruct.c configure.in crammd5/md5.h
+        stdint.h does not yet seem to be widely available causing
+        compilation to fail on some platforms.  Changed uint{16,32}_t to
+        unsigned{16,32}_t, detect correct sizes with autoconf and added
+        typedefs in ntlmstruct.c.  Changed detection types from int to
+        unsigned int in configure.in and made corresponding changes in
+        crammd5/md5.h.  Thanks to Ronald F. Guilmette for spotting this.
+
+
+2002-02-12 	Brian Stafford	<brian@stafford.uklinux.net>
+      * strcasecmp.c strncasecmp.c
+      	These now return the correct sign of result for differing strings.
+
+2002-01-30 Version 0.8.10p1 released
+------------------------------------
+
+2002-01-29 	Brian Stafford	<brian@stafford.uklinux.net>
+      * ntlm/Makefile.am
+	Added ntlm.h to list of sources.  This omission stopped 0.8.10
+	form building.
+
+2002-01-29 Version 0.8.10 released
+----------------------------------
+
+2002-01-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * various files
+	Copyright messages now show the correct year.
+	Minor tweaks to kill warnings when compiling with
+	--enable-more-warnings=picky.  In a few cases this meant adding
+	a few casts which superficially look unnecessary.  In other
+	cases this meant adding a number of #undefs to get a vanilla
+	ISOC environment.
+
+      * missing.h
+      	Added missing.h which has declarations for Posix/SUS functions
+      	which may be missing from system libraries on some platforms.
+
+      * snprintf.c configure.in
+        Detect broken or missing snprintf() implementations and replace
+        if necessary.  N.B. the replacement snprintf.c is taken from the
+        libmutt distro and it too, is broken.  However, it *does*
+        correctly truncate and \0 terminate output which is too long to
+        fit in the buffer and that is the behaviour I rely on.
+
+      * strdup.c
+	Added strdup() for systems which don't have it.
+
+      * examples/mail-file.c
+      	Check for errors when smtp_start_session returns.  Fixed
+      	authinteract so that responses are not accidentally overwritten.
+
+2002-01-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * htable.c configure.in strndup.c
+      	Altered code to avoid the use of strndup.  strndup.c is removed
+      	from the distribution.
+
+2002-01-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * ntlm/* configure.in
+	Added NTLM auhentication module.
+
+2002-01-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * concatenate.c errors.c siobuf.c
+      	Check return value from snprintf.
+
+2002-01-03 Version 0.8.9 released
+---------------------------------
+
+2002-01-02 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+      	Added -lsocket to list of libraries searched for getaddrinfo().
+
+2001-12-29 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c configure.in
+	Added hack for stupid SMTP servers that advertise AUTH using
+	non-standard syntax from an internet draft that never made it
+	into RFC 2554.	Because this feature is non-standard, it must
+	be explicitly enabled when configuring.
+	rsp_{helo,ehlo}() now reset the auth mechanism list before
+	processing the result.	Previously this was done only when AUTH
+	was advertised.
+
+      * smtp-auth.c
+	set_auth_mechanisms no longer resets the mechanism list
+	before processing.  Added a test to avoid duplicates in the
+	mechanism list.  select_auth_mechanism now guarantees to select
+	the *first* usable mechanism.  The net effect of these changes
+	is that multiple calls to set_auth_mechanisms accumulate.
+
+      * auth-client.c
+        Rearranged code in auth_set_mechanisms and load_client_plugin
+        avoiding the need to repeat the test for plugin acceptability.
+
+2001-12-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+	Compiling with picky warnings turned on was broken.  Also,
+	recent glibc versions seem to have decided that strcasecmp and
+	a few other functions are GNU extensions causing compiles to
+	fail because of missing declarations.  Naturally, autoconf does
+	not detect this.  Added a _GNU_SOURCE define to fix this on
+	potentially affected systems.  No, I don't like it either.
+
+      * strcasecmp.c strncasecmp.c strndup.c
+	Added these functions in case some systems don't provide them.
+
+2001-12-21 	Brian Stafford	<brian@stafford.uklinux.net>
+      * htable.[ch]
+      	h_insert now returns a void pointer to the data instead of a
+      	struct h_node eliminating the need for the h_dptr macro and
+      	for code using hash tables to maintain two pointers instead
+      	of one.
+
+      * headers.c
+	Updated to use the simpler hash table interface.
+
+2001-12-10 	Brian Stafford	<brian@stafford.uklinux.net>
+      * auth-client.c
+	Use dlsym and friends directly on platforms that have it.
+
+      * configure.in Makefile.am
+        Detect dlsym, fall back to using libltdl for other platforms.
+        libltdl is no longer distributed significantly reducing tarball
+        size.
+
+2001-12-10 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+        A missing comma caused the test for getipnodebyname to fail on
+        systems which provide it.
+
+2001-12-06 Version 0.8.8 released
+---------------------------------
+
+2001-11-30 	Brian Stafford	<brian@stafford.uklinux.net>
+      * crammd5/md5.h
+      	The len parameter of md5_update differed in type between
+      	prototype and definition, preventing compilation if size_t
+      	is not an unsigned int.
+
+2001-11-29 	Brian Stafford	<brian@stafford.uklinux.net>
+      * crammd5/*.[ch]
+      	Moved include of config.h from hmacmd5.h to hmacmd5.c.  Make
+      	sure sys/types.h is included since size_t is used.
+
+      * configure.in
+      	Added some extra nonsense for systems which redefine
+      	getaddrinfo to something else in netdb.h
+
+2001-11-27 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in errors.c
+	Add test for broken strerror_r on OSF-1.
+
+2001-11-12 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+	Updated the tests for pthreads.  Should now supply the correct
+	compiler flags on more systems.
+
+2001-11-07 Version 0.8.7 released
+---------------------------------
+
+2001-11-05 	Brian Stafford	<brian@stafford.uklinux.net>
+      * errors.h libesmtp.h
+	Improve handling of error codes from getaddrinfo.  Delay mapping
+	of codes to make debugging easier.  libesmtp.h defines new error
+	codes for the relevant EAI_XXX codes from getaddrinfo.
+	smtp_strerror will use gai_strerror if appropriate.
+
+2001-10-31 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+	Added test for sun platforms and define __EXTENSIONS__ so that
+	sun's netdb.h will declare the getaddrinfo stuff. (James McPherson)
+
+      * crammd5/md5.[ch]
+	Type sanity: change u_intXX_t to uintXX_t.  Also changed the
+	argument for the buffer and length to void * and size_t
+	respectively in md5_update.  Buffer for md5_final is now
+	unsigned char.
+
+2001-10-17 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	Fixed a core dump bug which strikes when existing headers in a
+	message are substituted.
+	
+      * Makefile.am
+	Reinstated libesmtp.spec into tarballs.
+
+2001-08-17 Version 0.8.6 released
+---------------------------------
+
+2001-10-17 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp-config.in
+	Corrected output for --cflags.  Added --numeric-version to make it
+	simpler for configure scripts to compare version numbers.
+
+      * configure.in libesmtp-spec.in
+      	Merged changes from Cristophe Lambin.  Spec file now creates
+      	libesmtp and libesmtp-devel packages.  If OpenSSL is used
+      	spec file will have openssl dependencies added.
+
+      * Makefile.am
+	Make sure libesmtp.spec and config.h do not make their way into
+	tarballs.  These confused the build on some platforms.
+
+2001-10-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+      	Added --with-openssl[=DIR] option, removed --enable-starttls.
+      	OpenSSL dependent features are now enabled or disabled en masse
+      	using --with-openssl.
+
+      * crammd5/md5.[ch] crammd5/Makefile.am
+	Added public domain MD5 implementation to crammd5 module.  This
+	enables the CRAM-MD5 mechanism to be built, even if OpenSSL is
+	not available.
+
+      * smtp-tls.c
+      	Applied patch from James McPherson correcting __attribute to
+      	__attribute__
+
+2001-08-05 Version 0.8.5 released
+---------------------------------
+
+2001-10-05 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp.spec.in
+      	Make sure libesmtp-config gets installed!
+
+      * configure.in
+	Removed STARTTLS's experimental status.  The code works and just
+	needs debugging.  Certificate management is basic but usable.
+      	Set defines for strict iso/posix/xopen in headers only when
+      	--enable-isoc is in force.  This helps avoid disabling the
+      	tm_gmtoff member in the BSD struct tm unnecessarily.
+
+      * siobuf.[ch]
+	sio_read/write use void buffers rather than char.
+
+2001-09-28 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-tls.c
+        Use the event callback to report STARTTLS in use if the security
+        level was OK.
+
+      * rfc2822date.c
+	Provide a function to portably calculate the timezone offset
+	when struct tm does not provide tm_gmtoff.
+
+      * configure.in
+      	Don't bother to check for gmtime[_r] since it isn't used any more.
+
+2001-09-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	Make sure set_to accepts NULL for the mailbox value.  Added set_cc
+	which is same as set_to except it fails with a NULL mailbox.
+
+      * Most files.
+        Changed references to RFC 821/822 to RFC 2821/2822 respectively.
+
+2001-09-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+	RFC 2822 requires only the originator and date headers to
+	be present in a message.  In particular, the presence of the To:
+	header is no longer required.  RFC 2822's restriction that
+	headers may not appear multiple times in a messge is enforced
+	respecting certain special exceptions.
+
+      * examples/mail-file.c
+        Added API call to make sure a To: header is generated if not
+        in the message.
+
+2001-09-14 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in acinclude.m4 acconfig.h
+	Reverted to configure.in, reinstated acconfig.h and added
+	some compatibility stuff to acinclude.m4.  All this to try
+	and be compatible with autoconf 2.5 *and* 2.13.  I really
+	hate autoconf.
+
+2001-09-05 	Brian Stafford	<brian@stafford.uklinux.net>
+      * getaddrinfo.c
+	Check if NO_ADDRESS is defined and different to NO_DATA
+
+2001-08-27 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-tls.c
+      	Move some detail of selecting STARTTLS to smtp-tls.c
+
+      * smtp-tls.c
+	Changed STARTTLS policy for Starttls_ENABLED.  If a server offers
+	STARTTLS, then it must be used and all security requirements must
+	be met.  If STARTTLS is not offered the session continues in
+	cleartext.  Previously, Starttls_ENABLED permitted a session to
+	continue with possibly compromised security.
+
+2001-08-22 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-tls.c libesmtp.h
+        More certificate management.  Added TLS event reporting.
+
+      * smtp-auth.c
+      	Fixed behaviour for zero length responses to server challenges.
+
+      * base64.c
+	Zero length passwords caused an assertion failure in
+	base64_encode.  base64_decode did not correctly strip blanks
+	from strings not terminated by \0.  Neither did it correctly
+	handle zero length strings.
+
+2001-08-21 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-tls.c libesmtp.h
+      	Added preliminary code for client certificate management.
+
+      * siobuf.[ch]
+	Changed sio_set_tlsclient_ctx to sio_set_tlsclient_ssl.  This
+	makes things slightly more flexible for supplying different
+	client certificates according to the remote host.
+
+2001-08-20 	Brian Stafford	<brian@stafford.uklinux.net>
+      * message-source.c
+	Fixed memory leak in msg_source_destroy. (Pawel Salek)
+
+2001-08-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.ac Makefile.am
+      	Change from using LIBOBJS to LTLIBOBJS.  This prevents the
+      	wrong objects from being linked by libtool when building
+      	dynamic libraries.  Added code to configure.ac to correctly
+      	set LTLIBOBJS and LTALLOCA.
+
+      * smtp-api.c protocol.c errors.c libesmtp-private.h configure.ac
+        Code now exclusively uses getaddrinfo.  Removed #ifdef code for
+	gethostbyname.  Added conditionals for using alternative lwres
+	library distributed with recent versions of bind.  Delete
+	--enable-gethostbyname option.  Add --enable-emulate-getaddrinfo.
+
+2001-08-14 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c
+	Remove unnecessary socket include files.
+
+      * getaddrinfo.[ch]
+	Added emulation of the RFC 2553 getaddrinfo resolver interface
+	for systems that don't have it.
+
+2001-08-13 Version 0.8.4 released
+---------------------------------
+
+2001-08-13 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+      	Completely ignore TLS extension if TLS is already in use.
+
+      * smtp-tls.c
+      	Fix wrong comparison when initialising OpenSSL mutexes.  Record
+      	the fact that TLS is in use.  Change a numeric constant to its
+      	symbolic equivalent.
+
+      * crammd5/client-crammd5.c
+        Correct a typo which prevented the hmac computation being
+        correctly rendered in hexadecimal.
+
+      * examples/mail-file.c
+      	Added --tls and --require-tls options and supporting code.
+
+2001-07-31 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.ac
+        Make plugin directory consistent with RPM.
+
+      * libesmtp.spec
+      	Applied patch from Pawel Salek to run ldconfig after installing.
+
+2001-07-30 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c configure.ac
+	Check for uname and use it in preference to gethostname which
+	is not Posix.
+
+2001-07-19 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.ac
+      	Check for the presence of the OpenSSL headers as well as
+      	the libraries.  Remove --enable-callbacks option.
+
+      * smtp-api.c libesmtp.h
+        Added smtp_version API call.
+
+      * message-callbacks.c
+      	Removed callbacks which did \n -> CRLF translation.
+
+      * examples/mail-file.c
+        Use libESMTP provided callback unless the --crlf option is
+        supplied.
+
+2001-07-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c
+      	Only include netinet/in.h if it is actually needed.
+
+2001-07-06 Version 0.8.3 released
+---------------------------------
+
+2001-07-06 	Brian Stafford	<brian@stafford.uklinux.net>
+      * examples/mail-file.c
+        Made --help more helpful.  Undocumented --no-crlf now renamed
+        to --crlf and documented.  When prompting for authentication
+        now reads /dev/tty instead of stdin.
+
+      * configure.ac
+        Check for -lsocket.
+
+      * protocol.c siobuf.c
+        Zero errno before calling certain functions.  Normally the value
+        of errno is only tested if the preceeding system call or function
+        wrapping the system call failed.  However, in a few cases, the
+        functions are called in a loop and the value of errno might
+        be tested after a successful return.  This meant that a test
+        on the value of errno might yield an invalid result, sometimes
+        causing the connection to the server to be incorrectly dropped.
+        Unfortunately this effect depended on the amount of data buffering
+        provided by the server!
+
+2001-06-29 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c et al.
+	Added support for sendmail specific XUSR extension.  This informs
+	sendmail the message is a user submission instead of relay,
+	so it makes sense to issue the command.  Whether it actually
+	does anything ...
+
+      * siobuf.c
+	Fixed return from poll in raw_read and raw_write so that EINTR
+	is correctly handled.
+
+2001-06-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * auth-client.c
+	Fixed a signed/unsigned comparison that stops compilation
+	when using -Werror.
+
+2001-06-26 Version 0.8.2 released
+---------------------------------
+
+2001-06-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c siobuf.c
+      	Resolved a problem related to blocking/non-blocking polling
+      	for server events.  This could lead to deadlock with certain
+      	servers.
+
+2001-06-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.ac  most C sources
+      	Added --disable-isoc option.  When using gcc, -ansi -pedantic
+      	are now specified by default since the code compiles without
+      	warnings when using both flags.
+      	Added --enable-debug option to control DEBUG and NDEBUG
+      	definitions.  Assert macros used to check arguments to
+      	most internal functions.
+
+2001-06-23 	Brian Stafford	<brian@stafford.uklinux.net>
+      * message-source.c
+	msg_gets now checks for both \r and \n when searching for line
+	endings.
+
+      * errors.c
+	API function now includes ommitted the arguments check.
+
+2001-06-22 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c configure.ac
+	Now uses RFC 2553 / Posix protocol independent getaddrinfo where
+	possible instead of gethostbyname family of resolver functions.
+
+      * gethostbyname.c configure.ac
+      	Added ability to use getipnodebyname and corresponding test
+      	for configure.
+
+2001-06-18 	Brian Stafford	<brian@stafford.uklinux.net>
+      * auth-client.c
+        More thorough argument checking on the auth_xxx APIs.
+	Added some missing malloc return value checking.
+	When loading a plugin, make sure it provides a response()
+	function.
+
+      * smtp-auth.c
+	Added some missing malloc return value checking.
+
+      * various sources
+	Changed some 'int' types to 'size_t'
+
+      * message-source.c
+      	In msg_gets, an inconsistent pointer could cause a segfault
+      	after a realloc which moved the original memory block.
+      	Increased sizes of malloc/realloc so that RFC 2821 maximium
+      	line length will not cause realloc.
+	Added missing malloc/realloc return value checking.
+
+      * protocol.c
+	If an error occurs while copying the message to the SMTP
+	server drop the connection without terminating the message.
+
+2001-06-15 Version 0.8.1 released
+---------------------------------
+
+2001-06-13 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+        is now configure.ac to suit autoconf 2.5
+	Eliminated some redundant stuff concerned with libtool.
+	Now uses AC_HELP_STRING macro where appropriate.
+	Now use standard AC_FUNC_STRERROR_R macro.
+	Improved checking for time.h and sys/time.h.
+
+      * libesmtp-config.in
+	If libltdl was installed, the list of libraries was set to the
+	wrong thing.
+
+      * errors.c
+        Only use strerror_r if it actually works.
+
+      * rfc822date.c
+      	Try sys/time for struct tm just in case!
+
+2001-06-12 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+      	Now checks -lnsl when seraching for gethostbyname_r.
+      	Only print a warning if strerror_r is not found.
+      	Chose much more picky compiler warnings when using gcc - this
+      	has knock on effects through many files.  Compiles should now
+      	be much cleaner on more platforms.
+
+      * siobuf.h
+        Gcc will now check sio_printf()'s argument types against the
+        format string.
+
+      * headers.c
+	Eliminated a variable which was set but not used.
+	The as yet unimplemented smtp_set_resent_headers API will
+	succeed if `onoff' is zero.
+
+      * protocol.c
+	Eliminated variables which were set but not used.
+	Fixed an uninitialised variable bug which might strike if the
+	EHLO command received a 5xx status code.  This is likely with
+	older servers and may result in libESMTP dropping the connection
+	instead of trying HELO.
+	Fixed an uninitialised variable bug which could cause the protocol
+	to QUIT inadvertently after processing the response to EHLO.
+
+      * errors.c
+        Rewrote handling of the thread specific data.
+
+2001-06-12 Version 0.8.0 released
+---------------------------------
+
+2001-06-11 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c
+	DELIVERBY extension done - still to test.
+
+2001-06-09 	Brian Stafford	<brian@stafford.uklinux.net>
+      * message-callbacks.c libesmtp.h
+        Added standard callback functions for reading messages. libesmtp.h
+        provides macros to simplify using them.
+
+2001-06-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * message-source.c
+	Changed the declaration of the message callback to make it clearer
+	that the first argument in fact points to internal state allocated
+	by the callback.  Strings returned to code reading the message
+	are now const char *.
+
+2001-05-31 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-api.c protocol.c configure,in
+	Had another go at the smtp_require_all_recipients() API hack.
+	The original implementation hoped the SMTP server would report
+	failure on receiving a zero length message but this isn't
+	reliable.  This API must be explicitly enabled by ./configure.
+
+2001-05-28 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-auth.c
+        Make sure the client won't attempt to authenticate when already
+        authenticated.  This could happen if having authenticated and
+        enables a security layer, the server offers AUTH again.
+
+      * smtp-tls.c
+        Make sure the client won't attempt to negotiate TLS when already
+        using TLS.  Also don't use TLS if already authenticated.
+
+      * siobuf.c
+      	Make the code for non-blocking sockets + OpenSSL more robust.
+
+      * errors.c
+	Added default case for set_herrno().
+
+2001-05-25 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-auth.c
+      	On authentication failure the same mechanism was selected again
+      	instead of moving on to the next one.  This caused an infinite
+      	loop of failing AUTH exchanges.
+
+2001-05-24 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp.spec.in
+      	Changed "-a 0" option in %setup macro to "-T -b 0"
+
+      * configure.in
+	Removed -Werror from --enable-more-warnings=yes as this can be
+	bothersome for punters.  Added --enable-more-warnings=picky to
+	stop gcc from using internal prototypes for builtin functions;
+	also turns on -Werror.
+
+      * protocol.c
+	free_ghbnctx() was called twice if connect() failed, potentially
+	causing a SIGSEGV.  This bug was introduced with support for
+	gethostbyname_r.
+
+2001-05-23 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in
+	Incremented library version and reset the age.  This is important
+	because the event callback semantics have changed.
+	Detect IPv6 sockaddr structure in <netinet/in.h>.
+
+      * protocol.c
+      	Added 8BITMIME support.  New API call smtp_8bitmime_set_body().
+      	Report extensions after final set is known.  STARTTLS or AUTH
+      	can change the set of extensions advertised by the server.
+        Typo meant the RET=FULL/HDRS parameter was printed as
+        SIZE=FULL/HDRS in MAIL FROM: (D'oh!)
+
+      * errors.c
+	Changed prototype for smtp_strerror() to allow use of strerror_r.
+
+2001-05-22 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c
+        Fixed calls to encode/decode callbacks and added explanation of
+        their semantics.  This eliminates potential for a buffer
+        overflow bug when decoding expands data read from the socket.
+
+      * libesmtp.spec.in
+	Fixed inconsistency between package name and tarball.
+	Use the bz2 version of the tarball as the source.
+
+      * Makefile.am
+      	Added libesmtp.spec to extra distribution files.
+
+      * gethostbyname.c
+	Added missing #include <string.h> (gcc builtin prototypes
+	again - grumble....)
+
+2001-05-21 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c
+      	Restructuring of reading/writing and polling to permit use
+      	of non-blocking IO.
+
+      * protocol.c
+	Revised protocol outer loop makes sure the protocol engine reads
+	data as soon as it becomes available and defers buffer flushes
+	until after pending data from the SMTP server has been read.  In
+	conjunction with non-blocking output this avoids a potential
+	deadlock described in RFC 2920 when PIPELINING is in use.
+
+2001-05-20 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-etrn.c
+	Added experimental support for the ETRN extension.
+
+      * protocol.c smtp-api.c
+      	Check for failure to create a message source and added code
+      	to actually destroy it thus plugging a memory leak.
+      	More thorough checking of some API function arguments.
+
+      * siobuf.c
+	Added sio_mark().  When the write buffer is flushed data written
+	beyond the mark is retained and the mark is deleted.
+
+      * protocol.c
+	Added new event types for flagging required extensions not
+	available or reporting extensions that provide information to
+	the application.
+	Command boundaries are marked in the write buffer.  This
+	prevents partial commands being sent to the SMTP server.
+
+2001-05-18 Version 0.7.1 released
+---------------------------------
+
+2001-05-18 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+      	Added AF_INET6 support.
+
+2001-05-17 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c gethostbyname.[ch] configure.in acinclude.m4
+	gethostbyname_r() now in its own file which provides a consistent
+	interface.  configure selects which version of the function to
+	compile for when building threaded code.
+
+      * configure.in auth-client.h libesmtp-config.in libesmtp.spec.in
+      	Directory for installing authentication plugins is now
+      	configurable.
+
+2001-05-15 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp.spec.in
+	Added to simplify building RPM packages.
+
+2001-05-14 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-api.c
+      	Check that all messages have a callback to read the message
+      	headers and body.
+
+      * tokens.c
+	Check buffer length in read_atom().
+	Use of <ctype.h> eliminated.
+
+      * headers.c
+        init_header_table() checks for NULL pointers to avoid potential
+        SIGSEGVs.
+
+2001-05-13 	Brian Stafford	<brian@stafford.uklinux.net>
+      * rfc822date.c configure.in
+	Use localtime_r() or gmtime_r() when building a thread safe
+	library.
+
+      * concatenate.[ch]
+      	Fixed incorrect shortfall caclulation in concatenate()
+      	potentially leading to buffer overrun.
+      	Generally tidied up code.
+
+      * auth-client.c
+      	auth_response() fails if (*context->client->init)() fails.
+
+      * base64.c
+	b64_encode() now checks the destination buffer length.
+
+2001-05-11 	Brian Stafford	<brian@stafford.uklinux.net>
+      * libesmtp-config.in Makefile.am
+      	Added config script to simplify compiling and linking.
+
+      * protocol.c configure.in
+      	Use gethostbyname_r() when building a thread safe library.
+
+2001-05-09 	Brian Stafford	<brian@stafford.uklinux.net>
+      * Makefile.am configure.in
+	libltdl is now part of the tarball and is installed if not
+	already present.
+
+      * protocol.c
+      	do_session() will now make use of all the addresses returned
+      	by gethostbyname().  This allows the DNS admin for the domain
+      	to specify a number of MTAs which handle mail submission.
+	Failures trying to connect or when processing the greeting or
+	a response to the EHLO/HELO commands will cause a fallback server
+	to be tried.  The name server will round robin the responses
+	balancing the load among the servers.
+      	When reading the server greeting accept only 220 otherwise the
+      	connection may have been made to a non-SMTP service.
+
+2001-05-06 Version 0.7.0 released
+---------------------------------
+
+2001-05-06 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+	session->auth_mechanisms was incorrectly freed in do_session().
+	This should have been done using destroy_auth_mechanisms().
+	Moved initialisation of the session variables to the start
+	of do_session().  This allows checks for some error conditions
+	to be done before attempting to connect to the SMTP server.
+	Updated code to select messages and recipients.  This is to
+	permit calling smtp_start_session() more than once on a given
+	session.  Second and subsequent calls should only deliver to
+	recipients not successful in a previous SMTP session.  Removed
+	a few FIXME comments that no longer apply.
+
+      * smtp-api.c
+        smtp_recipient_reset_status() clears the 'complete' flag so that
+        the recipient will be retried on a subsequent smtp_start_session().
+        Added a new API smtp_recipient_check_complete().  This is true if
+        a subsequent call to smtp_start_session() would *not* attempt to
+        post the message to this recipient.
+        smtp_destroy_session() now frees memory allocated for remote
+        server hostname.
+
+      * protocol.c libesmtp-private.h smtp-api.c
+        Renamed 'sent' in smtp_recipient_t structure to 'complete'.
+        Not all completed recipients might have been sent.
+
+      * protocol.c headers.c smtp-api.c
+        Only call gethostname() once and save the result.  Also added
+        new API smtp_set_hostname() to allow the application to change
+        the default.
+
+2001-05-03 	Brian Stafford	<brian@stafford.uklinux.net>
+      * crammd5/Makefile.am crammd5/hmacmd5.[ch]
+      	Renamed files to avoid name conflict with Cyrus SASL
+      	include/ directory.
+
+      * base64.c message-source.c
+	Added missing #include <string.h>, egcs-2.91.66 didn't
+	spot the missing prototypes.
+
+      * examples/mail-file.c
+        Ignore SIGPIPE.  Means the application isn't killed accidentally
+        when something times out during the protocol session.
+
+2001-05-02 	Brian Stafford	<brian@stafford.uklinux.net>
+      * sasl-tls.c protocol.c
+      	Added experimental support for STARTTLS
+
+2001-04-31 	Brian Stafford	<brian@stafford.uklinux.net>
+      * cram-md5/Makefile.am
+	hmac-md5.h was missing from the list of sources and hence was
+	not in the tarball.
+
+2001-04-29 Version 0.6.1 released
+--------------------------------
+
+2001-04-30 	Brian Stafford	<brian@stafford.uklinux.net>
+      * auth-client.c
+	Fixed incorrect SSF comparison for authentication modules
+	that were already loaded.
+
+2001-04-29 Version 0.6a released
+--------------------------------
+
+2001-04-28 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in smtp-api.c example/mail-file.c
+	Corrected inconsistently named API from smtp_set_auth_context()
+	to smtp_auth_set_context().
+
+2001-04-25 Version 0.6 released
+--------------------------------
+
+2001-04-25 	Brian Stafford	<brian@stafford.uklinux.net>
+      * configure.in Makefile.am */Makefile.am
+	Added detection of MD5 routines in OpenSSL, to enable
+	the CRAM-MD5 SASL mechanism.
+
+2001-04-25 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+	Corrected parsing bug in parse_status_triplet().
+
+2001-04-16 	Brian Stafford	<brian@stafford.uklinux.net>
+      * api.h
+	Added new header file.  This currently contains macros
+	to aid argument checking for API functions.
+
+      * libesmtp.h
+	Changed name of API function argument check macro.
+
+      * most files
+      	Wrapped #include <config.h> with #ifdef HAVE_CONFIG_H
+
+2001-04-11 	Brian Stafford	<brian@stafford.uklinux.net>
+      * rfc822date.c
+	Make sure the absolute value of minutes is used when
+      	formatting the date.
+
+      * protocol.c
+	Fixed potential segfault when DATA fails before transferring
+	a message.
+
+      * smtp-auth.c
+        Support for client authentication plugins now working.
+
+      * protocol.c
+	Support for SMTP AUTH extension.
+
+2001-04-05 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-auth.c
+	Removed 'want_enhanced' argument from read_smtp_response()
+	since it was unnecessary.
+	Added preliminary support for SMTP AUTH extension.
+
+2001-04-04 	Brian Stafford	<brian@stafford.uklinux.net>
+      * Many files
+	Changes to accomodate stricter error checking options
+	to gcc.
+
+2001-04-03 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c protocol.c
+	Changed CONFIG_TLS to USE_TLS (not that it matters yet)
+	Changed HAVE_LIBSASL to USE_SASL
+	Mostly for consistency with autoconf convention.
+
+      * configure.in
+	Checks for pthreads and SASL.
+
+2001-03-21 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-api.c
+      	Fixed up some missing error reporting.
+
+2001-03-15 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+      	Now sets timeouts reccommended in RFC 1123 when waiting for
+      	server responses.
+
+      * errors.c libesmtp.h
+      	Changed prefix from ES_ to SMTP_ERR_.  Edits to other files
+      	to accommodate the change.
+
+2001-03-14 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c libesmtp.h
+        Added first lot of event monitoring callbacks.  Simplified the
+        declaration for the callback function.  The callback is called
+        with different arguments depending on the actual event.
+
+2001-03-09 	Brian Stafford	<brian@stafford.uklinux.net>
+      * tokens.c tokens.h protocol.c
+	Added const to a few things that should have had it.  Fixed a
+	corresponding declaration in protocol.c.
+
+      * smtp-auth.c
+      	Basis of the implementation of the SMTP AUTH command.  This is
+      	not complete or tested yet, pending the decision about how to
+      	best implement SASL.
+
+      * siobuf.c siobuf.h
+      	Added callback functions which encode or decode data just before
+      	writing or after reading data between the buffers and the
+      	socket.  This is for use by SASL security layers.
+
+2001-03-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * concatenate.c concatenate.h
+	Added minimum_length parameter to cat_{init,reset}().
+
+2001-03-07 	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c siobuf.h protocol.c
+	Allow for seperate read and write file descriptors in
+	sio_attach().  This is for when support for opening a pipe to
+	a program running an SMTP server on its stdin/stdout is added.
+
+      * siobuf.c siobuf.h
+      	Fixed the #ifdef _buffer_h lines to #ifdef _siobuf_h (the perils
+      	of cut and paste editing).
+
+      	Added typedefs for the sio callback functions.
+
+      	Added encoder/decoder callbacks for use with security layer parts
+      	of SASL.  CONFIG_SASL stuff now gone.
+
+2001-03-02 	Brian Stafford	<brian@stafford.uklinux.net>
+      * headers.c
+        Implemented the rest of destroy_header_table().
+
+2001-02-27 Version 0.5 released
+--------------------------------
+
+2001-02-26 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+      	Now issue RSET before MAIL FROM: if a failure response is
+      	received to the DATA command.
+
+      	Fixed possible segfaults when resetting the status in rsp_rest()
+      	and rsp_quit().
+
+      * headers.c
+        Partially implemented destroy_header_table().
+
+      * smtp-api.c
+        Now calls destroy_header_table().
+
+      * htable.c
+	Allow callback in h_destroy() to be NULL.
+
+2001-02-26 Version 0.4 released
+--------------------------------
+
+2001-02-25 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+        Second state for the DATA command now does not transfer the
+        message if there were no valid recipients.
+
+2001-02-22 	Brian Stafford	<brian@stafford.uklinux.net>
+      * smtp-api.c
+        Added APIs to get/set application data in each of the opaque
+        structures.
+
+	Added protocol event callback API but only for a place holder.
+	This will be used by applications which want to monitor the
+	progress of the session and status changes as they happen.
+	This is different from the protocol monitor which dumps the
+	actual data transferred on or close to the wire.
+
+      * headers.c
+      	Added code to handle Sender:
+
+      	Fixed From: printing; continuation lines had no leading whitespace.
+
+      	In smtp_set_header_option() once Hdr_PROHIBIT is set, it cannot
+      	be unset.  Prohibit cannot be set for headers already set.
+
+	Added smtp_set_resent_headers() but only for a place holder.
+
+      * protocol.c
+        Correct parsing of enhanced status codes.  These are only present
+        for 2xx, 4xx and 5xx SMTP status codes.
+
+2001-02-18 Version 0.3 released
+--------------------------------
+
+2001-02-19 	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c smtp-api.c
+        Port number in session structure stored in host byte order
+        instead of network byte order.  This makes the port number easier
+        to read in gdb.
+
+      * protocol.c
+	Removed white space which crept into the MAIL FROM: and RCPT TO:
+	commands.  All the servers tested with to date have accepted
+	this but it wasn't in RFC 821.
+
+      * headers.c
+	Fixed From: and Disposition-Notification-To: headers to allow
+	multiple mailboxes as per RFC 822.
+
+	Corrected syntax for default Message-Id: generation.  This
+	should have been "addr-spec" per RFC 822 but didn't have an @.
+
+      * examples/mail-file.c
+      	Corrected typo that stopped --reverse-path from working.
+
+2001-02-18 Version 0.2 released
+--------------------------------
+      Core libESMTP API now complete.
+
+2001-02-18	Brian Stafford	<brian@stafford.uklinux.net>
+      * examples/mail-file.c
+      	Updated to tweak a few more APIs in libESMTP.
+      	The example now has a very basic Makefile.
+
+2001-02-17	Brian Stafford	<brian@stafford.uklinux.net>
+      * protocol.c
+        Changed use of strchr() to memchr() since strings read by the
+        message callback and header functions are *not* \0 terminated.
+
+      * headers.c
+	Changed beyond all recognition. :-)
+	Declaration of smtp_set_header_option() has changed.
+
+      * New files added to support RFC 822 header processing.
+
+2001-02-08	Brian Stafford	<brian@stafford.uklinux.net>
+      * siobuf.c
+      	Some additional error checking; extra thoroughness checking the
+      	return value of write().
+
+      * siobuf.c
+      * protocol.c
+      	Added the protocol monitor callback mechanism.
+
+      * libesmtp.h
+      * libesmtp-private.h
+      * smtp-api.c
+	Minor changes to the monitor callback declaration and session
+	structure for the protocol monitor.
+
+2001-02-04 Version 0.1a released
+--------------------------------
+
+2001-04-04	Brian Stafford	<brian@stafford.uklinux.net>
+
+      * message-source.c
+        Fixed a bad bug that could cause an infinite loop if a message
+        was not properly terminated with a \n
+
+2001-02-04 Version 0.1 released
+-------------------------------
+
+2001-02-04	Brian Stafford	<brian@stafford.uklinux.net>
+
+      * Initial Release
+
