Argh; mea culpa. Thanks for the very quick reply, Hans. It does work "as expected" (albeit deprecated)---Tracking down errors, I was misled by an error immediately following the deprecation warning and associated it with the warning, not the subsequent text.

Thanks,

Revisiting this one---as noted in the thread \, used to work in text mode;
according to the logs it was deprecated and now produces an error
preventing most of my documents from compiling.
Is there solution that restores \, (and friends) for abbreviated spacing in text mode
that doesn't require bulk changes to all of my documents
(and making the source documents hard to type/read)?
I appreciate using the more verbose \thinspace in macros
but the abbreviations have real value in bulk text,
especially when heavily used.
I have many uses throughout my documents where I need a thin space
(such as working with SI units) where it would be very awkward
to use \thinspace everywhere in the source text.
for example, consider a simple example that used to work but no longer does
with the alternatives that I'm aware of:
    32\,MiB--64\,MiB
    32$\,$MiB--64$\,$MiB
    32\thinspace MiB--64\thinspace MiB
The difference in both writeability and readability for these cases is significant
afaikt

\starttext
   test\,test
\stoptext

just works (\unit {32 mebibyte}--\unit {64 mebibyte} also works)
