the only things that really changed are

- input encodings, still supported but we assume utf8
- font encodings, font features etc that make for different specifications
- some fuzzy argument handling that made sense 25 years ago but not today
- some low level fatures that were never to be used at the user level
- improvements to mechanism that are now possible
- more was added than removed (and believe me: i'd like to remove some)
- if something fails also keep in mind that maybe it was never supossed 
to work but tex is just rather tolerant

take for instance math: we adapt to possibilities, unicode developments 
etc. but overall interfaces are kept (we eventually dropped $$ mkiv 
because it is hard to get spacing right otherwise, een with some nasty 
tricks)

\head is one of these "best use arguments" and les sknown is that we 
also dropped par delimited \section and such (the head one currently can 
be enabled with \autoparagraphmode4)

the main drive is 'better rendering' and 'less complicated coding'

you use for for instance \bigskip which is never going to guarantee good 
spacing as it doesn't cooperate with \blank and friends (it is sort of 
dangerous to mix what oen sees outside context with context commands 
like like loading that lua module, which actually is in none of the 
manuals)

if one wants to get an idea of coding context documents the 'source sof 
manuals' can show some
