0.5.9
=====
  03-Nov-2004:  - Released 0.5.9
  31-Oct-2004:  - fix: A negative response to an INVITE shall stop
                  any associated initiated RTP streams
  24-Oct-2004:  - Default Expires timeout is now configurable.
  23-Oct-2004:  - fix: route_processing.c - when adding my record-route header,
                  the 'lr' parameter was not dynamically allocated memory
                  (possible crash when trying to free is)
                - up to 1000 characters per line in config file (was 120),
                  some typos corrected (by Tero Pelander)
                - fix: various correction in Record-Route processing
  13-Oct-2004:  - utils.c: preparation for chroot() (consider syslog)
  09-Oct-2004:  - included startup script (by Guido Trentalancia)
                - siproxd.spec: create PID and registrations directories
                  and install startup script

0.5.8
=====
  22-Sep-2004:  - Released 0.5.8
  05-Sep-2004:  - Cross-provider calls (e.g. sipphone <-> FWD, with dial
                  prefixes) did not work properly
  04-Sep-2004:  - more on Route headers
  27-Aug-2004:  - preliminary (and reduced) support for Route Headers
  26-Aug-2004:  - more DEBUG output
  22-Aug-2004:  - fix: secure_enviroment - set proper EGID (by Daniel Mueller)
  19-Aug-2004:  - fix: don't crash on missing Contact header during registration
  18-Aug-2004:  - reworked configure.in for FLI4L building
  06-Jul-2004:  - patch from Dan Weber: Open the password file for SIP
		  accounts at startup, so we still have access after
                  chroot()ing. PID filename can be given at command-line.
                - again: using a port number != 5060
  27-Jun-2004:  - fix: in some configurations incoming requests could
                  be sent to a wrong port number.

0.5.7
=====
  24-Jun-2004:  - Released 0.5.7
  18-Jun-2004:  - 2 fixes for using a port number != 5060 (by Miguel Angel)
  13-Jun-2004:  - fix: get_ip_by_host() and buffer allocation for reentrant
                  gethostbyname_r() functions
                - if compiled for fli4l 2.0.x, don't use reentrant
                  gethostbyname_r() - in some cases it fails reproduceably
                  when running under fli4l (however, the same binary
                  does behave properly under an old SUSE libc5 system)
  12-Jun-2004:  - use SIGUSR2 for dmalloc debugging (SIGUSR1 is occupied
                  with old libc5 & threads)
                - reworked calling parameters for passing SIP data
  11-Jun-2004:  - silenced some MSN Messenger provoked WARNings
  29-May-2004:  - "determine next hop" also takes Route header into account
                  (outgoing packets only, incoming can not have a proxy
                  in between siproxd and the client anyway)
  25-May-2004:  - sip_utils.c:sip_del_myvia check for NULL list
  24-May-2004:  - included doc/sample_* to package
  23-May-2004:  - doc/: added configuration example for X-Lite

0.5.6
=====
  20-May-2004:  - Released 0.5.6
                - some cleanup in configure.in
  14-May-2004:  - FAQ update
  16-May-2004:  - INFO/WARN/ERROR are always logged to syslog, even
                  if running in foreground (syslog still can be silenced
                  using the silence_log config option)
  09-May-2004:  - Authentication headers: enquote Realm (linphone)
                - complain about empty values in config file
                - fli4l-uclibc: statically link against libpthread
                  (as it seems to be not included in fli4l distribution)
  02-May-2004:  - better recognition of redirected incoming requests
                  (like INVITES from sipgate.de - SIP URI points to
                  the real wanted target but To: header only points to
                  the initially wanted target before the redirection)
                - compiling on BSD (fwapi.c, custom_fw_module.c)
  11-Apr-2004:  - on termination, stop all active RTP streams
  24-Apr-2004:  - simplified SIP RX & TX routines

0.5.5
=====
  11-Apr-2004:  - Released 0.5.5
   9-Apr-2004:  - SDP body: do rewrite 'o=' (originator) address, too
                - siproxd can be linked to a customer firewall control
                  module (library) that will be called for each RTP
                  stream that is started/stopped.
   8-Apr-2004:  - small FAQ updates
   5-Apr-2004:  - config file: don't complain on lines with only whitespaces
                - fix: Via branch calculation
                - security.c: increased max acceptable line length
                - security.c: prevent libosip2 to die with "out of memory"
                  on some malformed headers
   4-Apr-2004:  - Realtime Scheduling for RTP proxy
   3-Apr-2004:  - fix: SDP 'c=' items in media part
   2-Apr-2004:  - PID file
  31-Mar-2004:  - accessctl.c: text correction in ERROR output
  30-Mar-2004:  - Again '*' Contact header in unREGISTER
                - new: tools/extract_sip.pl 
  26-Mar-2004:  - SDP rewrite: properly handle 'c=' items in session
                  *and* media part of SDP data.
  22-Mar-2004:  - deal with wildcard Contact header for unREGISTER
                - enhanced security tests to survive the PROTOS test
  21-Mar-2004:  - added ./autogen.sh
                - security_check_sip: check existence of mandatory headers
  19-Mar-2004:  - proxy_rewrite_invitation_body: check success of
                  starting RTP relay before rewriting SDP body
                - proxy_rewrite_invitation_body: don't fail on
                  Contact header with no user part.
  18-Mar-2004:  - security_check_sip: CSeq header must be present.

0.5.4
=====
   6-Mar-2004:  - Released 0.5.4
                - Some FAQ updates
  21-Feb-2004:  - Proxy Authorization: enclose strings with quotes
                  and fixed an error that did not let REGISTER
                  requests pass through to a 3rd party registrar.
  17-Feb-2004:  - Documentation spell corrections (patch from Luke Mewburn)
  16-Feb-2004:  - Hack for Grandstream SIP phones and SUBSCRIBE response

0.5.3
=====
  14-Feb-2004:  - Released 0.5.3
                - Removed superfluous backslashes for line continuation
  11-Feb-2004:  - Use same SIP port number for RX & TX (-> support
                  symmetric SIP signalling)
   7-Feb-2004:  - Fix for local-UA to local-UA RTP proxying, symmetric
                  RTP was not working.
                - logging routines now use a MUTEX to be thread safe.
                - RTP proxy: fixed a bug that could lead to a deadlock
                  on very rapid HOLD/unHOLD sequences.
   1-Feb-2004:  - Added handling of Max-Forwards header
                - a detected via loop results in an 482 Loop detected
  31-Jan-2004:  - Allow 2 of my vias in header to let 2 UA's sitting
                  behind the same siproxd have conversation together
                  UA1 -->--\   >   /-->--\
                            siproxd       Registrar
                  UA2 --<--/   <   \--<--/
                - Redone code for evaluation if a received packet
                  is coming from the inbound or outbound network
                - RTP streams are now identified by call_id AND
                  USERNAME of the contact header. This provides
                  support for RTP proxying between 2 UAs sitting on the
                  inbound network. -> Calls between local UAs going via
                  siproxd should now work.
                  UA1 -->--\
                            siproxd 
                  UA2 --<--/ 
                - Rewriting of SUBSCRIBE messages should now work.
                - Removed obsolete prototypes from rtpproxy.h
                - If the RTP stream in one direction is found to be
                  aborted (sendto() failure), also stop the stream
                  for the opposite direction

0.5.2
=====
  31-Jan-2004:  - Released 0.5.2
  30-Jan-2004:  - If RTP proxy is disabled, don't rewrite incomming
                  SDP bodies (patch from Robert H鰃berg)
  29-Jan-2004:  - new doc/RFC3261_compliance.txt and comments in the
                  code that refer to the RFC.
  28-Jan-2004:  - don't die on INVITE requests that include no Contact
                  header - which is legal. (patch from Robert H鰃berg)
                - RTP proxy: don't try to forward empty RTP packets
                - renamed some variables of rtp_proxytable_t to make
                  better sense (changed meaning in fullduplex RTP proxy)
  27-Jan-2004:  - added doc/KNOWN_BUGS
                - better branch parameter calculation (via header),
                  now honors RFC3261 for stateless proxies (section 16.11)
                - SIP request: remove a Route header pointing to myself.
                  This was an issue with Linphone 0.12.1.
                  (patch from Robert H鰃berg).
                - removed IPCHAINS & IPTABLES (netfilter) proxy support
                - RTPPROXY correction: match RTP ports crosswise -
                  use one single port (and socket) on each side (inbound/
                  outbound) to send and receive RTP traffic for every
                  active stream (patch from Christof Meerwald).
  22-Jan-2004:  - ./configure option: --enable-static to build
                  a completely statically linked executable
                - REGISTER honors the expires parameter
                  of the contact header
                - Contact header of REGISTER response must be
                  rewritten back to the local (true) URL
  18-Jan-2004:  - security_check_raw:
                  size check: >= 16 bytes
                - at exit, check registration file to be writable
                - no WARNING if SIP user-agent header is not supplied.
                - Call logging: distinguish between In & Out
                - include branch parameter for via headers

0.5.1
=====
  22-Dec-2003:  - Released 0.5.1
  21-Dec-2003:  - possibility to log call establishment
  17-Dec-2003:  - full duplex RTP proxy (many thanks to Chris Ross for
                  his work on this). Up to now, only the RTP *Relay*
                  has been tested (it works with KPhone, BudgeTone)
                - fix: SIP phones that allocate a random port for
                  incomming SIP traffic should now work (like BudgeTone)
                - fix: some SIP phones do change the RTP port number
                  during a session (like KPhone during HOLD/unHOLD)
                - textual corrections
  15-Dec-2003:  - use only even port numbers for RTP traffic
  05-Dec-2003:  - some changes & enhancements inspired by Chris Ross:
                  * 183 Trying *may* contain SDP data
                  * compare_url: now does compare the scheme,
                    if a host is not resolveable, hostnames will be
                    compared as strings
  04-Dec-2003:  - have registrations persistent across restarts of
                  the daemon ('registration_file' config option)
  29-Nov-2003:  - some documentation & FAQ updates

0.5.0
=====
  26-Nov-2003:  - released 0.5.0
                - included preliminary support for IPTABLES (netfiler)
                  based systems.
  24-Nov-2003:  - some fixes in sockbind() (FreeBSD) by Jeremy Shaw
  23-Nov-2003:  - got the gethostbyname() failure problem solved.
                  (the resolver needs a shared lib that was tried
                  to load AFTER chrooting...)
  22-Nov-2003:  - utils.c: use gethostbyname_r() in favor of
                  gethostbyname - if available (siproxd uses threads!)
                - some small items & cleanup
  19-Nov-2003:  - Integrated a patch from Chris Ross:
                  * have siproxd compile on Solaris and BSD/OS (more to come)
                  * ./configure option --with-libosip-prefix
                  * properly handle getopt_long()/getopt()
  18-Nov-2003:  - readconfig.c: include sysconfdir to the list of locations
                  where siproxd will search for its config file
  14-Nov-2003:  - rtpproxy.c: sys/types.h needed for *BSD
                - tested: siproxd builds on FreeBSD 4.9
   2-Nov-2003:  - rtpproxy bugfix: On repetitive INVITES, the UDP media
                  port could end up as -1 in the rewritten packet.
   1-Nov-2003:  - siproxd can use another outbound proxy (chaining)
                - Linux 2.4.x: siproxd with RTP relay could hang
                  on termination (Thread termination). Fixed.
                  
0.4.2
=====
  31-Oct-2003:  - released 0.4.2
                - Makefile: install siproxd to sbin (was bin)
  24-Oct-2003:  - SPEC file: included config files & more docu
  19-Oct-2003:  - included compiling support for DMALLOC debugging
