Lame3.98もいつの間にかbeta3

変更点でちょっと意外だったのは-kオプションの廃止です。

Changes in lame frontend switches: -k removed, add lowpass and highpass switches if you need to change them; --short/noshort/allshort - degraded into DEVELOPER ONLY switches normal users shouldn't use them; -X -Z degraded to DEVELOPER ONLY switches, -X is too tough to communicate to end users and -Z isn't used actualy

・・・ま、使うこともほとんどないでしょうし、いいか。
