Yate 2.2.0

 This is mainly a maintenance release including stability and
 performance fixes.
 The SIP parser performance was improved 2.5x.
 Fix for 100% CPU load on client when Qt use the glib event loop.
 Support for T.38 terminal mode fax in SIP.

Yate 2.1.0

 An implementation of the Cisco SLT and RUDP protocols allows
 Yate to control both signaling and voice on Cisco 5350 and
 54xx XM universal gateway series.
 Fixes in handling of PSTN circuits over MGCP.

Yate 2.0.0

 A new signaling stack is included providing support for PSTN
 ISDN, SS7 and analog lines. The new MGCP implementation allows
 Yate to control analog trunks or TDM circuits for CCS signaling.
 Clustering is supported by redirecting calls between node servers
 in the cluster and also providing Linux High Availability
 heartbeats to a third party controller.
 The Gtk client was removed and replaced with one based on Qt-4
 that should work better in Windows.

Yate 1.3.0

 This release includes many small improvments and bug fixes.
 Several border conditions in SIP are handled better by default
 and more of the SIP handling is configurable, including support
 for subscribing to mailbox and line status notifications. The
 PBX is able to store and copy any message parameter. Matching
 in the regular expressions module can be performed on function
 result and messages can be renamed or duplicated easily. More
 initial startup time is allowed by the supervisor as well as
 properly reaping all zombie child processes that may be left by
 external scripts. In client the ENTER key now works as expected
 by starting a call and adding to the callto combobox. The event
 window can be used to display debugging information.

Yate 1.2.0

 A Jingle channel suitable for implementing gateways is now
 available together with some STUN support for the RTP data.
 The PBX was improved a lot and quite complex operations can be
 described from the config file. Lots of minor improvments and
 bug fixes were made in the VoIP protocol drivers. Considerable
 improvements of the call forking module allow it to be used for
 special purposes like generating fake early media.
 A bug that could be used to crash a Yate process (but no way to
 take control) over the SIP protocol was fixed.

Yate 1.1.0

 Fax channel was almost entirely rewritten to work with a
 more recent version of spandsp. A tone detector module allows
 detecting fax tones and diverting the call. The database
 module can provide several fallback routes. A few TCP
 sockets are reusable so there is no problem quickly stopping
 and restarting Yate. A minor bug causing temporary noise in
 conference was fixed, also bugs in timestamp generation and
 RTP data splitting. Support for external Python scripts was
 considerably improved. The client got an event log window.

Yate 0.9.0pre3

 Minor improvments and bug fixes in this release. Called
 number is picked from Q.931 of the H.323 calls if it's not
 present as alias. A bug in default handling of SIP audio
 media was fixed. Warnings when compiling with gcc-4 were
 eliminated as well as an obsolete tag in the rpm specfile.
 A workaround for PHP's buggy array_walk was implemented in
 libyate.php

Yate 0.9.0pre2

 Support for the iLBC codec was added in both Linux and 
 Windows. The tone generator can generate DTMF sequences and 
 arbitrary sums or modulation of two sines, allowing  
 generation of inband DTMF. The SIP and H.323 channels  
 attempt harder to accommodate error conditions. It is now 
 possible to initiate a graceful restart from the Remote 
 Manager or by sending signals to the daemon. The engine will 
 wait until all plugins are idle. Some problems compiling   
 with gcc-4 or newer versions of Visual Studio have been fixed.

Yate 0.9.0pre1

 After a long wait Yate-0.9.0 is available. It comprises a lot
 of improvements starting with a fully rewritten engine, a new
 RTP stack, the Windows port, the conference module, the 
 Sangoma E1/T1 cheap cards support for both Windows and Linux.
 This new package also contains YateClient which is a 
 multiprotocol H.323, SIP and IAX VoIP client. It requires GTK
 2.6.8 for Windows and is fully skinnable.
