Compatibility changes
1. Integration change

SDK package change

Since v3.2.0, the following files have been added to the SDK package:

libagora-fdkaac.so: The Fraunhofer FDK AAC dynamic library.
libagora-mpg123.so: The mpg123 dynamic library.
libagora-soundtouch.so: The SoundTouch dynamic library.
If you upgrade the SDK to v3.2.0 or later, ensure that you have copied the above files to the folder where the libagora-rtc-sdk.so file is located.

Spelling correction

This release renames USER_PRIORITY_NORANL to USER_PRIORITY_NORMAL.

2. Cloud proxy

This release optimizes the Agora cloud proxy architecture. If you are already using cloud proxy, to avoid compatibility issues between the new SDK and the old cloud proxy, please contact support@agora.io before upgrading the SDK. See Cloud Proxy.

3. Security and compliance

Agora has passed ISO 27001, ISO 27017, and ISO 27018 international certifications, providing safe and reliable real-time interactive cloud services for users worldwide. See ISO Certificates.

This release supports transport layer encryption by adding TLS (Transport Layer Security) and UDP (User Datagram Protocol) encryption methods.

Transport layer encryption affects the size of the SDK package. For details, see Product Overview.
New features

Set the latency level as ultra low latency to use Interactive Live Streaming Premium.
Set the latency level as low latency to use Interactive Live Streaming Standard.

Improvements
1. Meeting scenario

To improve the audio experience for multi-person meetings, this release adds AUDIO_SCENARIO_MEETING(8) in setAudioProfile.

2. Voice beautifier and audio effects

To improve the usability of the APIs related to voice beautifier and audio effects, this release deprecates setLocalVoiceChanger and setLocalVoiceReverbPreset, and adds the following methods instead:

setVoiceBeautifierPreset: Compared with setLocalVoiceChanger, this method deletes audio effects such as a little boy’s voice and a more spatially resonant voice.
setAudioEffectPreset: Compared with setLocalVoiceReverbPreset, this method adds audio effects such as the 3D voice, the pitch correction, a little boy’s voice and a more spatially resonant voice.
setAudioEffectParameters: This method sets detailed parameters for a specified audio effect. In this release, the supported audio effects are the 3D voice and pitch correction.
3. Interactive streaming delay

This release reduces the latency on the audience's client during an interactive live streaming by about 500 ms.
