Hi Hans,
Font expansion (hz) seems to be enabled by default with the latest
upload.
If I compile this document locally with ConTeXt "2022.11.18 13:22":
\showframe
% \definefontfeature[default][default][expansion=quality]
    % \usetypescript[modern-base]
    % \setupbodyfont[reset,modern]
    % \setupalign[hz]
\starttext
        Hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello hello hello hello hello hello hello hello hello hello
        hello hello hello.

I get slightly different spacing than I do when I compile the same
document on live.contextgarden.net. If I compile the document with the
lines uncommitted on live.contextgarden.net, I get the same results as I
do on my local installation with the lines commented.
Personally, I think that enabling hz expansion by default is probably a
good thing, but this change will affect a very large number of documents
and you never mentioned it in the announcement email, so I suspect that
it was accidentally added when you added the math hz.
what you observe is likely a side effect of an increase in accuracy 
which gives a bit less drift in the pdf; expansion is turned off (it 
would increase runtime if turned on)
(increased accuracy was indeed a side effect of math but more to get rid 
of an annoyance at extreme resolutions)
