libopus 1.3.1
Apr 12, 2019
This Opus 1.3.1 minor release fixes an issue with the analysis on files with digital silence (all zeros), especially on x87 builds (mostly affects 32-bit builds). It also includes two new features:

A new OPUS_GET_IN_DTX query to know if the encoder is in DTX mode (last frame was either a comfort noise frame or not encoded at all)
A new (and still experimental) CMake-based build system that is eventually meant to replace the VS2015 build system (the autotools one will stay).

All features
