Key Features

* Alternate sample rates

* Jack detection

* Echo cancellation: WebRTC canceller, automatic gain control, drift compensation

* Virtual Surround module

* Xen Paravirtualised audio sink

* Fixed HURD support

* A2DP decoder quality improvements

Enhancements

* Eider adds a motion-compensated temporal denoiser, which gives higher quality than the older spatial denoiser.
* We've added support for new compilers and platforms, including improved Xcode support, Android x86 NDK build, OS/2 support and SunCC support.
* Input resolution may now be changed without re-initializing the codec.
* The vpxenc application has initial support for producing multiple encodes from the same input in one call.

Performance Improvements

* With Eider, our focus was on decoder speed and realtime encoder speed.

Large realtime encoding speed gains with little quality loss are possible using the on-the-fly bitpacking experiment. Video conferencing-style encodes can be up to 13% faster, depending on resource allocation, with loss in the range of 0.2dB.

* Decoder speed improved 2.5% vs. Duclair.
* Two-pass encoding of slideshow-like material will see significant speed improvements.
* Quality is consistent with Duclair, but saw some useful tweaks:
* Reduced blockiness in easy sections, by penalizing intra modes.
* Improved quality of static sections (like slideshows) with two-pass encoding.
* Improved keyframe sizing with multiple temporal layers.

Many thanks to all who worked on Eider, and welcome to four new contributors:

Noteworthy Changes

There were a few important bugfixes since KDevelop 4.3.0, hence you should update as soon as possible.

Improved C++ support

On machines that already use the recently released GCC 4.7, you need KDevelop 4.3.1 to ensure proper support for many C++ stdlib classes in our language support. This is due to the usage of the new C++11 noexecept keyword in the stdlib header files, which was not supported by KDevelop until now.
Furthermore we managed to resolve a nasty bug in our template support, which so far could freeze our parser when processing specific template code. This means you can finally use the famous Eigen library among others in KDevelop again.

Other Bugfixes

Beside the notable changes above, KDevelop 4.3.1 comes with lots of bug fixes for our PHP and QtHelp documentation plugins, the PHP support and other areas. As usual, we also managed to resolve a few crashes. For the full overview, take a look at the changelog files.

Many thanks as always to the various contributors who made this release possible.

RELEASE HIGHLIGHTS

* Added support for the following GPUs:

GeForce GT 635M
GeForce 610M

* Closed a security vulnerability which made it possible for attackers to reconfigure GPUs to gain access to arbitrary system memory. For further details, see: http://nvidia.custhelp.com/app/answers/detail/a_id/3109

* Fixed a bug that caused DisplayPort devices to occasionally fail to turn back on after the system is resumed from suspend.

* Added a ModeValidation X configuration option token, "AllowNon3DVisionModes", to allow modes that are not optimized for NVIDIA 3D Vision to be validated on 3D Vision monitors.
