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.

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) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl -----------------------------------------------------------------
