-Agora Server Gateway can be deployed on your server to transmit audio and video streams to apps developed with Agora’s Voice and Video SDKs. The Server Gateway SDK enables communication between server and app through Agora’s global network (SD-RTN). Server Gateway can be used as a server-side gateway for media processing such as speech-to-text, for first- and third-party extensions, or can act as gateway service for Agora media services such as Media Push and Media Pull.

+## Version 4.2.30
+
+v4.2.30 was released on February 6, 2024.
+
+### New features
+
+- Multipath network transmission
+
+    This release adds the multipath network transmission feature, which allows simultaneous transmission of audio and video streams over multiple network paths. For example, when you insert two IoT SIM cards in the device, the SDK can transmit audio and video streams through the network of both SIM cards, thereby improving the stability and reliability of audio and video transmission. Contact [email protected] to enable and use this feature.
+
+- Hardware encoding acceleration
+
+    This release supports utilizing NVIDIA GPU hardware acceleration for video encoding, which reduces the power consumption of CPU and improves hardware encoding efficiency and performance. Contact [email protected] to enable and use this feature.
+
+### Improvements
+
+- Audio sending timestamp
+
+    To set the timestamp at which you send the audio data, this release adds the `presentation_ms` parameter in the `sendAudioPcmData` method. In scenarios such as video conferences and remote collaboration, this parameter allows you to achieve audio and video synchronization.
+
+### Bug fixes
+
+This release fixed the following issues:
+
+- App memory growth caused by receiving H.264 video raw data.
+- Garbled data stream when using both string-type user IDs and data stream functions simultaneously.
