Version history for LAME

Changes from v3.98 Beta 7 to v3.98 Beta 8

LAME now accepts a floating point value in the range [0,...,10[ as VBR quality setting, like -V5.678
Found and fixed some suspicious code in additive masking calculation for VBR-NEW
bug-fix:experimental code was defaulted by accident for VBR-NEW
fix for some endianess problem on big-endian machines

Changes from v3.98 Beta 6 to v3.98 Beta 7

libmp3lame API: allow frontends to separately retrieve LAME/Xing and ID3 data, because the old library automatism makes it impossible to make fully buffered encodes.
libmp3lame API: added some experimental unicode ID3 tagging code.
frontends: write itself final ID3 tags and LAME/Xing header frame
lame_enc.dll: writes itself final LAME/Xing header frame
Latest changes to the new VBR psymodel:
uses a different spreading function
bug-fix for out-of-bounds array access (program stack corruption possible)

Changes from v3.98 Beta 5 to v3.98 Beta 6

Feature request [ 1811483 ] WAVE_FORMAT_EXTENSIBLE support (PCM)
Fix for some rare scalefactor selection issue the newer vbr code had at low compression levels
Fix for Bugtracker item[ 1813496 ] AIFF parsing bug
Latest changes to the new VBR code:
it now has its own psy model, a derivation from NSPSY.
some more tuning has been done for this new psy model. Many thanks to Horst Albrecht and Myles Thaiss.
the "out-of-bits" strategy is reworked
It was possible, that the "interchannel masking effects feature" was used by the dual-channel-mode for bi-lingual encodings too. It was meant to work on stereo L/R channels only.

Changes from v3.97 to v3.98 Beta 5

Fix for Bugtracker item [1590693] ID3v2 tag not writing
Fix for Bugtracker item [1636267] ID3v2 tags overwritten
Fix for Bugtracker item [1719593] Track numbers > 255 not allowed even with --id3v2-only
Fix for Bugtracker item [1742623] fail(lame --mp3input -m m -b 128 --resample 8 *.mp3 **.mp3)
Fix for Bugtracker item [ 1445175 ] Input being stdin fails in Windows on WAV files
Fixing some memory leak in the 'lame_enc.dll'
Fix for Bugtracker items [1160757, 1160741] --little-endian / --big-endian not working
Fix for Bugtracker item [1746336] Incorrect Bitrate with ABR und --resample, LAME 3.98b4
