A conservative maintenance continuation
The final official stable release in this collection. It preserves output behaviour very close to 3.99.5 in the site tests, while the tested plain Windows build shows a substantial speed regression.
LAME 3.100
- Development focus
- Maintenance, portability, decoder work, and targeted fixes rather than a wholesale VBR redesign.
- Observed character
- Closely related to the 3.99.5 output family, but markedly slower in the site’s tested plain builds.
- Branch significance
- Extending the mature 3.99 family as the final stable release.
