upcoming betas

[Hans Hagen]

Hi

We currently have

   mkii : which uses pdftex/xetex
   mkiv : which uses lua(jit)tex 1.10

and next year we will also have

   lmtx : which runs luatex

functionally there is no difference between mkiv and lmtx but there are 
some diferences under the hood. It might also turn out to be a bit more 
efficient (at least this is what experiments here indicate).

The lmtx version is part of a "long term stability" approach and it will 
probably take some time (and esp testing) to reach that goal. When 
experiments work out well, the next context meeting will be showtime.

One of these days I will ask context dev to test this version because 
decisions have to be made on how to roll this out. The reason that I 
mention this development is that in upcoming beta releases one can run 
into (not that dramatic, easy to fix) issues related to reshuffing some 
code. I might also involve users who (I know) runs massive amounts of 
complex documents.

Because there is no functional change there are no consequences for 
daily use of context. However, there can be additional functionality at 
some point. So, from the users perspective lmtx is just mkiv, but in 
some places it will identify itself as lmtx (which is handy for checking).
