After more than two years of work, Opus 1.5 is out. It brings many new features that can improve quality and the general audio experience through machine learning, while maintaining fully-compatibility with previous releases. See this release page demonstrating all the new features, including:

- Significant improvement to packet loss robustness using Deep Redundancy (DRED) - Improved packet loss concealment through Deep PLC - Low-bitrate speech quality enhancement down to 6 kb/s wideband - Improved x86 (AVX2) and Arm (Neon) optimizations - Support for 4th and 5th order ambisonics'
