Reworked VBR modes with improved audio quality (Full range 24 - 384 kbit/s for Stereo, 16 - 192 kbit/s for Mono, and 96 - 960 kbit/s for 5.1) (details)
Fraunhofer FDK AAC encoder HE-AAC and HE-AAC v2 modes in MPEG-4 ISO BMFF (M4A) now use “Explicit hierarchical signaling” (previously using “Explicit backward compatible signaling” for compatibility with the old AAC-LC-only decoders)
HE-AAC & HE-AAC v2 MPEG-4 ISO BMFF (M4A) gapless now conforms with MPEG-4 Part 24 (ISO/IEC 14496-24) specification
Updated Apple AAC encoder support, can be used from the new iTunes Desktop versions (v12.10.9.3+) and from the iTunes Microsoft Store version
No longer writes obsolete 'replaygain_originator_code' tags to MPEG-4 ISO BMFF (M4A) files
Updated the output formats descriptions list for clearer appearance
