Unreal Engine 4.11 - Wwise 2015.1.6

The Wwise Unreal integration is now a plug-in. Please see Migrating from the UE4 Wwise integration source code to the plug-in version for migration notes.
UI-273 Fixed: Create a new uasset type for Auxiliary Busses. This allows to assign an AuxBus to a SoundBank. See AkAuxBus for more information.
UI-280 Fixed: Deprecated "...by name" methods, and replaced then with a string field in the relevant methods. See Migrating "...by name" methods for more information.
UI-309 Fixed: Made the Wwise project path relative to the game folder, instead of relative to the UE4Editor.exe file. See Migrating the Wwise project path for more information.

Unreal Engine 4.10 - Wwise v2015.1.4

UI-265 Fixed: In the AnimNotifies, test the AkComponent's validity before using it. This reduces log spam when using UE with the -nosound option.
UI-270 Fixed: It is now possible to build in non-Unity mode.

Unreal Engine 4.9 - Wwise v2015.1.2

UI-249 Fixed: Avoid crashing when no Audio Playback device is available on Windows.
Added a "Spawn AkComponent at location" Blueprint node. See Spawn Ak Component at Location for more information.
Added support for the Mac Editor.
Added support for the Mac platform.
Added support for the iOS platform.
Added support for the Linux platform.

Unreal Engine 4.8 - Wwise v2015.1

Migrated the UE4.8 integration to Wwise 2015.1
Fixed a crash on Xbox One if the app manifest did not contain a definition for Wwise communication ports.

Unreal Engine 4.8 - Wwise v2014.1.5

UI-206 Fixed: Sounds with an attenuation can now be heard when an animation window is opened.
UI-212 Fixed: Added a "Load Init Bank" Blueprint node.
UI-213 Fixed: Added null checks in Blueprint nodes, preventing crashes.
UI-214 Fixed: No crash when saving an output capture to disk.
UI-215 Fixed: No issue with the Attenuation Scaling Factor of an AkComponent not being set when attached to an actor.
UI-217 Fixed: Made AkReverbVolume's collision settings visible in the details panel.
UI-220 Fixed: Fixed the occlusion fade behaviour for sounds that a spawn occluded.
UI-223 Fixed: The gathering of the max attenuations for AkEvent does not halt when the parsing of one SoundBank fails.
UI-226 Fixed: SoundBank generation is now performed by the 32-bit WwiseCLI.exe when the 64-bit WwiseCLI.exe is missing.
UI-230 Fixed: Now using OnComponentDestroyed instead of FinishDestroy to unregister Wwise Game Objects, which had caused some Game Objects to be registered for too long.
UI-233 Fixed: Added validity checks on actors in the GetGameObjectID function.
UI-234 Fixed: Multiple viewports in the SetListener function are properly handled. This fixes a crash in AkAudioDevice.cpp.
UI-236 Fixed: The Location Type given to the GetAkComponent Blueprint node is properly handled.
UI-239 Fixed: No crash at engine shutdown as a result of the Bank Manager unloading SoundBanks that might already have been destroyed.
Added a "Follow" checkbox to the AnimNotify_AkEvent. Leaving it unchecked will post the AkEvent at a specific location, instead of attaching to the parent.
Added a new AnimNotify: AnimNotify_AkEventByName, allowing to post events using their name as a string.
Added Debugging tools to Blueprints. For more information, see Debug Blueprint Functions

Unreal Engine 4.7 - Wwise v2014.1.3

Added support for the Android platform.
Now including a new demonstration game, based on Epic's First Person Template. For more information, see Sample Game.

UI-188 Fixed: When an AkAmbientSound is about to be destroyed, cancel its event callback to avoid using a destroyed object in the callback.
UI-189 Fixed: Added an attenuation scaling factor to AkComponent, allowing to make each actor's attenuation radius unique.
UI-190 Fixed: Added a new Blueprint node that allows setting the exact list of loaded SoundBanks. For more information, see Load Banks
UI-193 Fixed: Get the UAkAudioEventFactory directly when creating UAkAudioEvents by Drag & Drop.
UI-194 Fixed: Optimized the finding of AkReverbVolumes at a location.
UI-195 Fixed: Added blueprint_actor_posteventbyname, features_blueprintcsoundbanks_loadbyname, and Unload Bank Blueprint nodes.
UI-196 Fixed: Added a configuration parameter for the maximum number of concurrent Reverb Volumes applied on a sound.
UI-201 Fixed: Added an UAkAudioEvent to AkComponent, to bring it in sync with Unreal's AudioComponent. An AkComponent can by added in a Blueprint via drag & drop of a UAkAudioEvent. An actor with an attached AkComponent will also show its attenuation radius in the Editor.
UI-204 Fixed: Added code to unload auto-loaded SoundBanks.
UI-205 Fixed: Don't post events in a world that does not allow audio playback.
UI-208 Fixed: Fixed a potential crash when generating SoundBanks.

Unreal Engine 4.6 - Wwise v2014.1.1

Added Japanese documentation.

July 2014 - Wwise v2013.2.9

Added a SwitchDemo map to the UnrealWwiseDemo sample game, demonstrating the use of switches.
UI-161 Fixed: Removed the duplicate AkComponent created when starting an ambient sound. This prevented the Stop Ambient Sound method from working.

June 2014 - Wwise v2013.2.8

UI-152 Fixed: Add SoundBanks and streamed files to the packaging process.

April 2014 - Wwise v2013.2.7

UI-149 Fixed: Set proper default values for AkReverbVolumes.

Visual Studio 2013 is now used by default. Please refer to the Requirements page for more details.
UI-146 Fixed: Fixed non-unity build compilation errors.
UI-147 Fixed:
- Verify the SoundEngine is initialized in the AkComponent tick function;
- Properly set the collision channel name for AkReverbVolumes;
- Avoid loading banks in a commandlet;
- Removed the automatic bank creation mechanism.
UI-148 Fixed: Use "Get Player Controller" in the RTPCDemo Blueprint to ensure sound keeps playing when transitioning between "Simulate" and "Possess" modes in Editor.

January 2014 - Wwise v2013.2.5

Added an example of AkAnimNotify in ShooterGame. It is located in the FPP_RifleReload animation.
UI-131 Fixed: Spatialized sounds are now audible in the Animation Editor: Added a second listener for the Animation Editor window, and routed game objects created in this window to the new listener. WARNING: This fix changes the AnimNotify_AkEvent Blueprint. If you have made modifications to it, be sure to keep a backup before merging this integration.
UI-134 Fixed: Removed the input flag StopWhenOwnerDestroyed to GetAkComponent. It was unused and could create confusion. Added a SetStopWhenOwnerDestroyed method to the AkComponent.
UI-136 Fixed: Allow Wwise Authoring to communicate with an Xbox One application.
UI-137 Fixed: Make sure a temporary game object (created by "Post Event at Location") is subject to AAkReverbVolumes.
UI-138 Fixed: Prevent the Sound Engine from creating UE errors while running in a commandlet. This is a workaround. Maybe the Sound Engine should not be initialized at all.
UI-139 Fixed: Removed FMath::Abs on Z projection when setting listener position in SoundEngine (Unreal code has been left untouched). This allows upside down listeners.
UI-145 Fixed: Fixed an error in the AkComponent::SetRTPCValue method that prevented RTPCs from being properly applied.

Fixed crash in UAkComponent::PostAkEvent with null event.
Fixed game object position with static actor.

August 2013 - Wwise v2013.2

Fixed confusion between Actor, AkComponent, the Wwise game object and their respective lifespans:

Fixed missing Events and Banks in SoundBank Definition File.
Fixed game object names in Wwise Profiler.
