Recent betas have introduced a bidi-related problem with register
processing.
In the following example, compilation generates a recoverable error when
register processing has to trim an entry to fit maxwidth. The error is:
luatex warning > node filter: error: ...eXt/tex/texmf-context/tex/context/base/mkiv/typo-dub.lua:496: attempt to index local 'stacktop' (a nil value)
Removing the maxwidth constraint, or setting it to a much wider value,
allows error-free compilation.
Without \setupdirections[bidi=on,method=two] there is no problem, but
without it RTL texts are not handled properly. This is a recent change;
bidi=global worked a few months ago. (I have not tried with LTR text in
a default-RTL document).

Here is a much-closer-to minimal example.
\setupregister [index] [maxwidth=4cm]
\setupdirections [bidi=on,method=two]
\starttext
.\index{Mairzy doats and dozy doats and liddle lamzy divey}
\placeindex
\stoptext
With the \setupdirections line removed, all is well. However, that line
is otherwise required. Setting bidi off around \placeindex is not an
option either, since some index entries require it.

And shorter still, isolating the problem to something in \limitatetext:
\setupdirections [bidi=on,method=two]
\starttext
\limitatetext {Mairzy doats and dozy doats and liddle lamzy divey} {4cm}
\stoptext

Tricky ... i'll catch it but better use method tree then (later this
year i might redo some r2l code)

That allows the compilation to complete, but method=three breaks other
stuff. Try this:
\starttext
\setupdirections [bidi=on,method=three]
\rightaligned{(( How is this?}
\stoptext
(I also see problems with boxes set in the margin where before they were
set centered in the textblock, but cannot construct an example yet.)

small samples will help (after i updated the beta)
