There are several reason for additions and changes. One + is that we need to support \OPENTYPE\ fonts and after more than a decade struggling with the + fact that many fonts are a mix between what the \OPENTYPE\ specification describes (its + accuracy evolved a bit over time) and what traditional \TEX\ fonts do. Think of the role that + italic correction plays in \TEX\ and kerns in \OPENTYPE\ math. + + In \LUATEX\ this has resulted in a way to control various elements of the engine so that one + can adapt to the font. Here even more properties can be controlled. However, in the end we + decided that fonts are too inconsistent and unlikely to be fixed, so in \CONTEXT\ we settled + on a combination of engine control and patching fonts runtime (aka goodie tweaks). This does + actually mean that in principle we can remove most of the code related to italic correction + and simplify kerning, which makes for cleaner code. We can then also ditch many control + options. It could also make some of the resulting constructs les scomplex (this is something + that might happen eventually anyway). + + In addition to this, the machinery below also has opened up atoms, fractions, accents, fences, + radicals and more beyond what \LUATEX\ already added. We have more classes (including user + ones), more spacing and penalty control, positioning features, etc. Most of that is not + described here but in documents that come with \CONTEXT\ and articles in user group journals. + + It is unlikely that users will set up the engine beyond what a macro package provides, which + should be reasonable defaults. Keep in mind that the math machinery has never be part of + discussing extensions to \TEX\ and that the math subengine was never touched. So, while + \CONTEXT\ users sort of expect this upgrade path, this is not true for other macro packages, + especially when they are considered standard and provide standard behaviour. This means that + we can go a bit further in setting up the engine (by options and parametsrs) in ways that + provide better output. This means that even with the same input, the output that \CONTEXT\ + produces will look different and hopefully somewhat better. + + One can of course wonder why we think the rendering can be improved and part of the answer is + in the fact that we have double linked node lists. This means that we can go back and forward + over the result. Another apects is that we have less constraints in memory and processor + capabilities, so we can carry around more information and spend more time on analysing and + calculations. Nodes are way bigger and the font system is more dynamic, which comes at a + price not possible when original \TEX\ showed up.
