-Release Notes for siproxd-0.4.2
+Release Notes for siproxd-0.5.0
 ===============================
 
+As quite some changes have been made now, I decided to make another
+release - even if some new feature are not yet completely ready,
+like IPTABLES (netfilter) support in the RTP proxy.
+However, it includes some important bugfixes and some other goodies.
+
+Major changes since 0.4.2:
+ - Feature: Proxy chaining - siproxd itself may now use an additional
+   outbound proxy. This allows for example to chain serveal siproxd
+   (cross multiple firewalls).
+
+ - Feature: Includes *preliminary* support for IPTABLES (netfilter)
+   based systems. Current restrictions: The executable 'iptables'
+   must reside in /sbin/iptables. Chroot jail not working.
+   Must be run as root, don't let siproxd change the UID.
+   This item is stil under work, it may or may not work for you.
+
+ - Feature: Some changes to have siproxd compile under Solaris.
+   Runtime is not tested yet.
+
+ - Fix: Bugfixes and cleanup for building of FreeBSD
+
+ - Fix: Chroot jail did not work properly and resultet in ERRORs
+   during hostname lookups (gethostbyname)
+
+General Overview:
  - May be used as pure Outbound proxy (registration of local UAs
    to a 3rd party registrar)
  - Fli4l OPT_SIP (still experimental) available, check

 ---------------------------------------------------------------------------
+Q: I have a Gradstream Budgetone-100 SIP phone. The SIP communication
+   seems to work properly (I can register, make and receive calls) but
+   I do not hear any audio. However, transmitting audio works.
+
+A: It has been observed that these SIP phone seems to be delicate there.
+   You should use the IPCHAINS based RTP proxy and your SIP phone must
+   be configured to use random ports. Connect with the web browser to
+   the phone and make sure the 'Use random port' option is enabled.
