• Add IPv6 support in all protocols
• Add BufferAudioSource to stream PCM buffers provided by the user
• Add onStreamingStats callback with byte accurate send queue monitoring (StreamingStatsReport and Throughput) (by @bratta-dk)
• Add getQueueBytesOut to stream clients (by @bratta-dk)
• Add QueueAwareBitrateAdapter, a bitrate adapter driven by the send queue instead of the measured bitrate
• Add BufferPool to reuse buffers in senders and record controllers
• Add Camera2 white balance lock and tap to meter (exposure and white balance) methods (by @bratta-dk)
• Add setCustomRequest and setCustomOnCaptureCompletedCallback to Camera2
• Add FlvMuxerRecordController as record fallback in Camera1Base for API 17 and lower
• Move object filters to Kotlin, unify sprites and fix filters rotation. AndroidViewFilterRender renamed to ViewFilterRender, GifObjectFilterRender to GifFilterRender, ImageObjectFilterRender to ImageFilterRender and TextObjectFilterRender to TextFilterRender
• Refactor SpriteGestureController
• Refactor all video and audio sources and fix leaks
• Change source now fallback to the last source if the new one fails
• Move H264, H265 and AV1 parsers to common and fix SpsH265Parser, Av1Parser, BitBuffer and G711 codec
• Allow set gl debug with a static value
• Refactor gradle and allow compile with Kotlin 2.1
• Fix video timestamp jitter using the frame timestamp instead of the render clock, in the encoder and in FpsLimiter
• Rebase surface PTS on the shared start instead of the first video frame, fixing audio lagging video (by @x270880x)
• Announce the rotated resolution, so portrait streams are not pillarboxed (by @x270880x)
• Prevent a bitrate or stats report failure from stopping the send loop (by @bratta-dk)
• Fix Camera1 fps range calculation
• Fix enableAutoFocus to clear the regions set by tapToFocus
• Properly remove the Camera2 handler on close
• Fix CameraX stop and file sources loop
• Fix BitmapSource fps using a frame interval instead of a fixed sleep
• Fix reloadCodec and prefer color format 19 on low API if possible
• Avoid crash calling getCapabilities in CodecUtil
• Fix BitrateManager reset to also reset the timestamp
• Stop gl after the encoders
• Fix tryClear crash if the SurfaceTexture is already released
• Fix UrlParser and fallback auth in getFullPath
• Add ACCESS_LOCAL_NETWORK permission to the example app, needed to stream to a local network server targeting Android 17+
• Update AGP to 9.3.1, Kotlin to 2.4.10, ktor to 3.5.2 and media3 to 1.11.0
