0.7.0
=====
  19-Jan-2008:  - Released 0.7.0
  19-Jan-2007:  - Converting to use libosip2-3.x.x
                  This means older libosip2 versions before 3.0.0
                  are no longer supported and will fail to build!

0.6.1
=====
  19-Jan-2008:  - Released 0.6.1
                  This will be the last release supporting libosip2-2.x.x.
                  With 0.7.0, siproxd will switch to the new version 
                  libosip2-3.x.x.
  20-Dec-2007:  - DNS failure cache: do several attempts before blacklisting
  28-Nov-2007:  - Fix: Detach from controlling TTY if daemonized
  22-Nov-2007:  - Working on code that that will allow siproxd to use
                  separate interfaces in its "in front of NAT router" setup.
                  ( UA1[LAN0]--siproxd--LAN1--NAT--Internet--UA2 )
  12-Nov-2007:  - Small changes to compile again under OpenBSD.

0.6.0
=====
  28-Oct-2007:  - Released 0.6.0
  03-Sep-2007:  - keep failed DNS attempts in cache for 10 minutes.
                  This should protect from repeating DNS timeouts
                  caused by broken DNS server (possible DOS)
  16-Aug-2007:  - added comment in siproxd.conf about hosts_allow_sip
  30-Jun-2007:  - some come cleanup in log.c (Bob Beers)
  22-Jun-2007:  - fixed an error in "my via" detection when using the
                  "host_outbound" config directive
  08-Jun-2007:  - Some cleanup in dejitter code
  29-May-2007:  - Deal with PRACK requests (RFC3262)
  25-May-2007:  - Just discovered some patches originating from Debian
                  project - included most of them as they make sense.
                  (Hint: People, if you get fixes, please drop me a note
                  and a .diff - I won't be biting you)
  24-May-2007:  - new feature: can masquerade User-agent header
                - new feature: can add ;rport to my own Via Headers
  13-May-2007:  - deal with locally running UAs on same host (inbound IF side)
  07-May-2007:  - Client-ID in RTP proxy is derived from Client IP address.
                  This should fix an issue with unexpectedly timing-out RTP
                  streams (actually too many RTP streams get started).
  21-Apr-2007:  - Hack to deal with Asterisks broken Alert-Info headers
                  (Asterisk in some setups does include Alert-Info header
                  without '<>'. Note, this is a configuration issue in
                  Asterisk, not an Asterisk bug!)
  19-Feb-2007:  - Increased RTP buffer size
  13-Oct-2006:  - Various fixes due to a code review by Andrew Jones
  05-Oct-2006:  - route_determine_nexthop(): don't remove header
  19-Aug-2006:  - increased DNS cache
  18-Jun-2006:  - included RTCP support and a de-jitter feature
                  (submitted by Hans Carlos Hofmann)

   1-Oct-2005:  - [1278537] Read proxy_auth_pwfile after config file is read
                - [1278591] Proxy-Authenticate header not included in response

  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)

=====
  22-Sep-2004:  - Released 0.5.8
  05-Sep-2004:  - Cross-provider calls (e.g. sipphone <-> FWD, with dial
                  prefixes) did not work properly

  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

  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

  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

                - 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
