Changes to qaac 2.82:

- Enabled Non-Linear adaptive coding enhancer (NoLACE) when (and only when) decoding opus in MP4 container.
- libopus >= 1.5 built with --enable-osce (which is off by default) is required (binary attached here).
- Unfortunately, ordinary .opus file is supported only via libsndfile, in which case qaac has no direct control over libopus. Hence only MP4 file is supported.

- qaac is a CLI. Check GUI vs CLI: A Comparison of Two Software Interfaces guide.
- See Using qaac without iTunes tutorial.
