+= Release 0.9 =
+
+== New Features and Enhancements ==
+
+Many new features have been implemented on this release.
+
+=== Audio quality improvements ===
+
+This release contains many improvements to stability, latency, and in general quality of audio:
+ * Implementation of Waveform Similarity Based Overlap-Add (WSOLA) algorithm (ticket #497) which provides the base algorithm for buffer expansion/compression and packet loss concealment.
+ * Ticket #438 fixed many problems related to audio impairments:
+   - fixed the click noise produced by splitcomb or conference bridge upon underflow/overflow situation (which normally happens when there is drift in audio device)
+   - much better buffering in splitcomb and conference bridge, with the ability to learn the optimal buffer length and shrinking/extending the buffer as necessary without degrading audio quality too much.
+ * New conference mixing algorithm which does not weaken the signal unlike to old algorithm (ticket #449)
+ * New packet loss concealment for G.711 and GSM codec (ticket #502)
+ * Boost the priority of master port/splitcomb to avoid audio disruption because of CPU usage (ticket #501)
+ * Optimize the delay in the jitter buffer (ticket #505)
+ * Much better stereo support all the way, including support for mixing ports with different channel number in the conference bridge (ticket #504)
+
+
+=== Secure RTP (SRTP) ===
+
+SRTP have been implemented and it is available for all platforms including Symbian and Windows Mobile. The implementation uses [http://srtp.sourceforge.net/srtp.html libsrtp], and SDES is used for the key exchange.
+
+=== G.722 codec ===
+
+The G.722 codec is now included in the standard source distribution and it is available for all platforms.
+
+=== TURN Relay support ===
+
+TURN has been implemented. The implementation is based on [http://tools.ietf.org/html/draft-ietf-behave-turn-07 draft-ietf-behave-turn-07] draft and with the default settings should be compatible with the newly released [http://tools.ietf.org/html/draft-ietf-behave-turn-08 draft-ietf-behave-turn-08] draft.
+
+In addition to integration with ICE all the way up to PJSUA-LIB and pjsua sample application, simple command line TURN client and server implementation samples are provided.
+
+=== ICE enhancements ===
+
+The SDP offer/answer procedures related to ICE have been enhanced and should now comply to the latest [http://tools.ietf.org/html/draft-ietf-mmusic-ice-19 draft-ietf-mmusic-ice-19] draft.
+
+=== IPv6 Support ===
+
+Support for IPv6 has been added in PJLIB, PJSIP, and PJMEDIA libraries. However some features are still missing, such as asynchronous DNS AAAA resolution and IPv6 support in pjsua sample application.
+
+
+
+=== RTCP XR support ===
+
+Support for subset of RTCP XR (RFC 3611) has been implemented (see ticket #513)
+
+=== Improved Windows Mobile sample application ===
+
+A new and more usable sample application !PocketPJ has been provided for !PocketPC/Windows Mobile based platforms.
+
+=== Improved Symbian support ===
+
+Carbide C++ is now supported, and a [wiki:DevelopingSymbianAppWithCarbide tutorial on developing PJSIP application with Carbide C++] is provided. More codecs have been ported to Symbian, including GSM and Speex.
+
+=== !ActiveSocket Framework ===
+
+The new [http://www.pjsip.org/pjlib/docs/html/group__PJ__ACTIVESOCK.htm ActiveSocket] framework in PJLIB provides higher and easier to use abstraction to create asynchronous sockets, utilizing PJLIB's [http://www.pjsip.org/pjlib/docs/html/group__PJ__IOQUEUE.htm ioqueue].
+
+=== More Thorough Tests ===
+
+Last but not least, in addition to existing tests for each library, 100+ automated test scripts have been added to test PJSUA-LIB to test functionality, conformance, and quality of various parts of the library.
