Nasm 2.0 Release

Nasm 2.0 在11/30 Release 了, 其實11月以來就一直可以看到最後修正的CVS一直上傳, 我是大概知道更新了什麼,不過怪的事nasm網頁老是不寫出Changelog, 總是覺的很怪, 不過這一天再看alt.lang.asm上看到Frank 咧出changelog 了, 所以記錄一下吧.

FWIW, here's the full "CHANGES" for 2.00 (thanks Chuck!):

最主要的改進應該算是x86-64的加入吧, 這樣正是yasm興起的主因, 而我比較在意的SSSE3到SSE5 全面補齊, 不過以目前來看,明年初的45nm 的CPU release 只有到SSE4.1 而已, SSE4.2 與SSE5 支援的感覺上有點是刻意補齊功能與yasm對抗
