btw, Prof. Knuth think compatibility as a very important issue because
he uses plain TeX.
His book usually calculate the page number/cross reference/index
himself (see TeXBook or Concrete Math).
If the line-break algorithm is changed, he should recalculate all the numbers.
With advanced typesetting macros like ConTeXt or LaTeX, document
complication uses serveral passes and the cross-references are always
right. Moreover, If we cannot make it fully compatible (pixel level),
why should we bother about the issue? Modern users won't care about
them (as Macro packages like ConTeXt are changing more rapidly).

Hi,
so, best use a recent version
Well, I switch to the luatex in the current context minimals(0.31.3, I believe). I have a essay (typesetted in ConTeXt using TeXGyre Palatino font) which only have plain text and math formula. I compile the document using MKIV and MKII, and the linebreak results are very different. Maybe that's because MKIV and MKII are different. I will test some plain TeX document later.
