20/12/21 2.02.05 - Studio API minor release (build 122665)

Features:

- Core API - HTML5 - Added a new FMOD_OUTPUTTYPE called FMOD_OUTPUTTYPE_AUDIOWORKLET, which uses the Web Audio AudioWorkletNode functionality.

Fixes:

- Studio API - Fixed issue where an async instrument would not trigger if its delay interval was greater than its length on the timeline.
- Studio API - Fixed issue where the description of an event retrieved from a start event command would have an invalid handle unless first retrieved via Studio::System::getEvent.
- Studio API - Start Event Command Instrument now gracefully handles the case when the event it is trying to start has not been loaded.
- Studio API - Fixed issue where the scatterer instrument can spawn instruments inconsistently under certain conditions.
- Studio API - Fixed issue where audibility based stealing would not use FMOD_DSP_PARAMETER_OVERALLGAIN::linear_gain_additive in its calculation. For events using the object spatializer or the resonance audio source this would cause the attenuation to be ignored for stealing.
- Studio API - Improved general Studio API performance.
- Studio API - Improved determination of whether a nested event will end, reducing the incorrect cases where it would be stopped immediately.
- Studio API - Fixed Studio::EventInstance::getMinMaxDistance returning -1 before event starts playing.
- Core API - GameCore - Fixed very rare Opus decoding hang.
- Core API - GameCore - Improved convolution reverb XDSP recovery in case of unexpected hardware failure.

09/09/14 1.05.00 - Studio API minor release

Important:

- Studio API - Studio::MixerStrip has been replaced by Studio::Bus and Studio::VCA. The new classes do not have a release method, as their handles remain valid until the bank containing them is unloaded.
- Studio API - Studio::System::getEvent, Studio::System::getBus, Studio::System::getVCA, and Studio::System::getBank now take a string path. Functions that take an ID are now named Studio::System::getEventByID, Studio::System::getBusByID, Studio::System::getVCAByID, and Studio::System::getBankByID.
- Studio API - Studio::EventInstance::release no longer invalidates the handle immediately. The handle remains valid until the event stops and is actually destroyed. In addition, this function now succeeds even if the event will not stop naturally.
- Studio API - Events with sounds triggered by parameters will now stop rather than going idle when all sounds have finished and the timeline cursor has reached the end.
- Core API - The wide string argument of System::getDriverInfo () and System::getRecordDriverInfo() has been removed. These functions now return UTF-8 encoded strings.
- Core API - FMOD_UNICODE flag for System::createSound () and System::createStream () has been removed. These functions now accept UTF-8 encoded file names to load sounds with non-ASCII characters on Windows, PS3, PS4, PS Vita, XBox One, iOS, Android, Mac, Linux, Windows Phone, and Windows Store.
- FSBank API - FSBANK_INIT_UNICODE flag has been removed. All file name structure members and function arguments now accept UTF-8 encoded strings.

- Core API - Android - Reduced latency for devices that support FastMixer, see "Basic Information" section of the docs CHM for details.
- Core API - Added DSP::setWetDryMix so any effect can have generic wet/dry signal level control.
- Core API - Added 3D ChannelGroup support. A ChannelGroup is a 'group bus' and it can now be positioned in 3d space, affecting the mix for buses and channels below it. 3D Cones, geometry etc all work. Use ChannelGroup::setMode (FMOD_3D) to enable a 3D ChannelGroup.

Fixes:

- Studio API - Fixed transitions to the end of a loop region failing to escape the loop.
- Studio API - Fixed sends inside events occasionally having a brief period of full volume when the event is started.
