Indeed, and that is to be expected. LuaTeX 0.74 is a major change in the sense that it uses Lua 5.2 and it's no big deal for context garden users as they can update to the latest. The latest beta runs ok with older luatexs.
One should be careful in just replacing luatex in for instance a tex live tree or frozen copy of a garden tree. As far as I can see the impact of the 5.1 -> 5.2 move is not that large at the code level yet (a few deprecated or renamed core lua functions) apart from a speed gain of some 5-10% on the average. I already did some adaptions to 5.2 as soon as it came out.
Of course using 0.74 in the garden standalone is fine as one updates luatex binaries in sync with context source code.
At the moment it is not exactly fine since LuaTeX hasn't been built for every platform yet (on some it doesn't even compile), so some users get 0.72.0 and some get 0.74.0. If you tell me to do so (or even if not ;), I can roll back to LuaTeX 0.72.0 until all (major) binaries get up to date and until ConTeXt gets fixed. Mojca
