Hi,
luatex 0.74.0 has problems with an escaped string which used to work in
0.72. Small example (typeset git information, so may only work in
directory under version control):
\starttext
git revision \ctxlua{context(os.resultof("git --no-pager log
--pretty='\%h of \%aD' -1"))} \crlf ConTeXt version: \contextversion]
\stoptext
I get
! LuaTeX error [string "\directlua "]:1: invalid escape sequence near '\%'.
system > tex > error on line 3 in file test.tex: LuaTeX error ...
All best
Thomas
