	* fsm_uas4req.c:
	   rigth names of callbacks.

AM 17/09/01
	* VxWorks:
	 * route.c: method route_init() already exist on VxWorks.
	 * makefile.mai: support for VxWorks.
	 * osip.h: add #include <time.h>
	* remove the unused error management support (err_t)
	* API:
	 * complete the API for parser...
	 * complete the API for fsm...
	* ..... so many changes....

AM 11/09/01
	* example/example_rcfile.c
	  add comments for the use of a sipproxy on VxWorks.
	  remove the unused 'domain' attributes.
	* configure.in
	  add better managements for configure's options:
	     --disable-mt
 	     --enable-pth
	     --disable-pthread
	* fsm/port_fifo.c: 2 implementations
 	  a fifo with semaphore (compiled with -DOSIP_MT)
	  a fifo without semaphore (compiled with -UOSIP_MT)
	  The second implementation does not provide the
	  method 'void *fifo_get(fifo_t*);'. Instead, you
	  must always use 'void *fifo_tryget(fifo_t*);'
	* correct method name
	  freefifo_t() changed to fifo_free()

AM 10/09/01

	* separation has been made between:
  	  * parser     the SIP parser.
	  * fsm        the state machines.
	  * example    architectural design and logic of application.
	  * example_mt architectural design and logic of application.
	    ***src is removed***

	   The new API is flexible enough to create your
	   own architecture design for your application.

	   You can now implement as many architectures you want:
	   * ./example provides a ONE process example architecture.
	   * ./example_mt provides a 1 thread/transaction example architecture,
	     one thread for the timers and one for a UDP listeners.
	* moved-files:
	  plenty...
	* new files
	  in osip: osip.h, list.h, fifo.h, sema.h, thread.h
	* --disable-mt:  remove -DOSIP_MT
	  If you use the command (./configure --disable-mt), you
	  will only be able to use the ./example/
	  If you use the default command, oSIP will be build with 
	  multithreaded support. (-DOSIP_MT)
	* TODO
 	  by now, fifo are implemented with semaphore even in non-multithread
	  design. A replacement will be provided so no library at all will be
	  needed.

AM 04/09/2001

	* re-organisation of the stack:
	  fsm:    contains the finite state machines and
	          optionnal timer facilities.
	  parser: contains the SIP parser and the
	          SIP message and headers accessor API.

	  The new objective is to provide a set of methods
	  independant from the application architecture.
	  Also, the transport layer has been moved towards
	  the application.
	
	  By now, port_sema.c and port_thread.c will be
	  optionnally compiled in oSIP. This may change
	  in next versions. As before, implementors can
	  choose their own implementation of threads and
	  replace the needed methods.
	* macro: TRACE() and DEBUG()
	  those new MACROs removes the printf() and trace()
	  calls to speed the application when compiled
	  with --disable-debug and --disable-trace.
	* trace() -> change prototype.
	  Make use of the __FILE__ and __LINE__ MACROs generated by
	  the compiler.

AM 27/08/2001

	* route.c/record_route.c:
	  new method record_route_2char() wich ALWAYS
	  use brackets which are mandatory for route
	  and record_route headers.
	* test/Makefile.am:
	* example/Makefile.am:
	  add the following line to enable building the package
	  in a saparate directory.
	     INCLUDES = -I$(top_srcdir)
	configure.in: move to 0.6.2 release
	cvs tag rel062

AM 26/08/2001

	* hdr_from.c: from_char(), from_parse()
	   1. when quotes are used for the displayname,
	   the parser now include them in the displayname.
	   This is for interoperability issue with other
	   limited stack.
	   2.  
	        from_params = strchr(url,';');
	    changed to:
	        char *host = strchr(url,'@');
		if (host!=NULL)
	      	  from_params = strchr(host,';');
		else
		  from_params = strchr(url,';');
	* msg_parser.c:
	  Add support for multiple header on the same line.
	   a nasty behavior is that we can't print the message
	   as it was received! This stack only output
	   a message by using multiple lines for multiple fields.
	* msg_parser.c:
	  When LWS are found, \n and \t are replaced by SPACE.
	   Same remark as above...
	* url.c: in url_parse()
	  be sure the host and port part of the url
	  has no SPACEs around.

AM 24/08/2001

	* hdr_header.c:
	  new prototype and new name for msg_getnheader(..., header_t **dest);
	     msg_getfindheader
	  new prototype for msg_getheader(..., header_t **dest)
	  new header_get/set method for name and value
	* msg_read.c: !MEMORY LEAK at the end of msg_2char()!
	  tmp was allocated with malloc()... instead of smalloc()
	  without any  sfree(tmp)...

	* url.c/url.h: extend the accessor API to build and read url.
	* url.c: 2 bugs in url_parse():   :-(
	   ->>> password = next_separator(username+1,':','@');
	   ->>> if (port>headers) port = NULL; /* Bug fixed: 24/08/2001 */

AM 23/08/2001

	* hdr_via.c/udp_send.c: modify msg_getvia(..., viat_t **dest)
	  prototype.
	* hdr_*.c/url.c:
	  * new access methods on url_param_t.
	  * new generic_param_t structure wich replace via_param_t,
	    from_param_t, to_param, content_type_param....
	  * new access methods on generic_param_t
	* hdr_*.c/smsg.h:
	  extend the accessor API (method and MACRO) of the SIP headers.
	configure.in: move to 0.6.1 release
	cvs tag rel061

AM 22/08/2001
	
	* udp_send.c: udp_send() is moved at the beginning
	    of the file and its declaration is removed from
	    trlayer.h (it is not a global method....)
	    getsock() is also moved at the beginning of the file.
	* fsm_uac4inv.c: in uac_i_retransmitack()
	    add a missing call to OnEvent_rcvresp_retransmission()
	    to announce reception of many 200 response.
	* trn_timers.c and timers.h:
	    remove duplicate code between uas/uac timers.
	    Now, only one thread deals with uas/uac transactions
	    new trn_execute(): This new method allow applications
	    to start the timers when they need it without using the
	    provided design.
	    Note that this module can be completely replaced by
	    applications that want to control retransmission on their
	    own.
	* url.c: BUG in next_separator()
	    tmp MAY not be assigned if before_separator==0
	    FIXED
	* smsg.h: remove msg_body_parse(). This is a private
	    method. Also, the file msg_body.c is useless and removed.
	    the method is moved in the msg_parser.c file.
	* msg_write.c remove msg_makereply() from the src/ directory
	    to the example/example_agentlogic.c file. It's more
	    appropriate.
	* hdr_body.c/smsg.h: add msg_getbody()
	* smsg.h: rename all set/get MACRO definitions to
	    msg_set*/msg_get*.
	            remove extra MACRO set/getcontenttype()
	* trn_manager.c: in trn_thread()
	    remove unused variable "i"

AM 21/08/2001

	* in example_logic.c: sip_invite(): remove unused
	    test/initialisation of from and contact.

	    move method declarations from fsm_*.c/sip.h towards this file.
	* new file: osip/timers.h for all timers related declarations.
	    move method declarations from transactionnal_design*.c
	    towards this file.
	* osip/Makefile.am: add timers.h and fsm.h
	* trn_manager.c: call_id_match(), callleg_match(), cseq_match()
	   * return code of from_compare is 0 on success.
	   * basic tests for bad arguments (avoid crashes when called
	       with NULL args).
	* trn_manager.c: in trn_init()
	     * BUG: if trn_init fails, mutex is not unlocked!!!
	* trn_manager.c:
	     * the global mutex is now initiated by a call to 
	       trn_global_init() called from sip_start_design()
	* port.h/port_thread.c/trn_manager.c:
	     * add sthread_join()
	     * add sthread_setpriority() (for VxWorks only)
	     * add sthread_exit()
	* hdr_from.c: in from_compare()
	     * return code is 0 on success.
	     * basic tests for bad arguments (avoid crashes when called
	       with NULL args).
	* udp_send.c:
	    add a connect() before the sendto so the second call to sendto
	    will failed with errno setted to ECONNREFUSED.
	* fsm_uas4req.c: in fsm_load_uas4req()
	    the last transition appears twice...
	* fsm_ua*4*.c: in uac_r_rcv2XX(), uac_r_rcv3456XX(),
	               in uac_i_rcv2XX(), uac_i_rcv3456XX,
	    remove useless test (the fisrt test is always true)
	    and remove the extra code that is never executed.

AM 18/08/2001

	* add optionnal code for LINPHONE from Simon Morlat for linphone0.4.0
	  (UA available at linphone.free.fr)
	  This transport part is likely to be modified a lot. 
	  This is the reason why I did not made it available 
	  in the standard distribution.
	  To use it: compile with -enable-linphone
	* Debug and Trace is now set as default option.
	  use --disable-trace --disable-debug to turn options off

	* cvs tag rel060

AM 17/08/2001
	
	* record-route/route.
	  * modif of sip_t structure, smsg.h, smsgtype.h, msg_cparser.c,

	  * new hdr_route.c file.

AM 14/08/2001
	
	* hdr_from: in from_parse(...)
	  if (displayname>url)
	      displayname = NULL;
	  to support those kinds of url where 
	  the first '"' is after the first '<'
	* trn_manager.c: in callid_match()
	  add support for callid without @ (with callid->host==NULL)
	* Many improvements for the test application:
	 * optional use of a proxy for all request
	 * use the "localip" value (from the config file)
	   which is added in the via header of request.
	 * the from value in the config file must include
	   a tag. (this is mandatory in the RFC)

AM 13/08/2001

	* BUG: message body does not end with an additional CRLF
	  change the parser so that it is able to calculate
	  automaticly the content-length and so that it does
	  not rely on the final CRLFCRLF sequence to find the
	  end of the body. (see rfc2543 section 8)
	* msg_bye.c -> set cseq to cseq+1
	* example_agentlogic.c -> add a contact header in 200
	                          response for INVITE.

	   a transaction is not finished. (This is mainly to
	   correct a behaviour that will occur on local tests)
	   if (transaction->lastrequest!=NULL)  {
     	   CHANGED TO:
	   /* if (transaction->lastrequest!=NULL) { */
	* app.c/example_rcfile.c:

	some modification for VxWorks, (more to come...)

AM 25/07/2001

	* Fixes some missing features of the new parser:
	  * in msg_body_parse: use sep_boundary instead of "--++".
	  * support for empty value in generic-parameter
	* url_param_set(): Add a call to sclrspace()  for generic-parameter.
	
AM 25/07/2001

	* release-0.6.0
	* new SIP parser
	* new MIME support

	The API for the parser is completely new. Each method
	has an err_t parameter which will be used later to
	improve error managements. (Actually, you are just
	aware that an error occurred, you don't know what is
	the type of error.)

	API for parser and sip_t:
	msg_init(sip_t **sip);
	msg_setto(to_t *to, char *string, err_t *err);
	msg_setfrom(from_t *from, char *string, err_t *err);
	msg_setcall_id(call_id_t *ci, char *string, err_t *err);
	...

	API for headers:
	 * example for to_t:
	 int          to_init(to_t **to, err_t *err);
	 void         to_free(to_t *to);
	 int          to_parse(to_t *to, char *hvalue, err_t *err);
	 int          to_2char(to_t *to, char **dest, err_t *err);
	
	The PARSER is now fully compliant and understand
	many features of SIP messages such as escaped characters,
	comments in Via, lws characters....

	What's missing:
	  *  better granularity in error management tasks.
	  *  simple accessor API on messages and its headers.
	  *  Multiple fields on the same line separated by a
	  comma are not supported.

	The library had been adapted to the new parser and
	tested for memory leaks. The ./example/ua application
	seems to be stable. Also, some new tests for headers
	are provided.

	The example application has also been modified to reflect
	changes and I also correct the command line for application.
