List,
I have one document that after the 2018-11-18 update (beginning with
12-01 and continuing to the current 12-07) has generated hundreds of
spurious missing character messages in the log. A short extract:

There are similar reports for the other fonts used in the document
(Antykwa Torunska is used for heads, EBGaramond with Libertinus fallback
for the body).
I have pared down the files to the following example which demonstrates
the problem. I do not understand now all the features interact to cause
this, but the reports disappear upon removing any (such as the
seemingly-redundant \definebodyfontenvironment or the
\switchtobodyfont[small]).
\enabletrackers
[fonts.missing]
\definebodyfontenvironment
[11pt]
[a=1]
\definefontfallback
[fb:ebgr]
[file:libertinusserif-regular]
[0x204A]
\starttypescript [serif] [ebgaramond]
\definefontsynonym [Serif]
[file:ebgaramond-regular]
[fallbacks=fb:ebgr]
\stoptypescript
\define\Test{¡Missing!}
\setupbodyfont
[ebgaramond,11pt]
\setupbodyfont
[libertinus,11pt]
\starttext
\dorecurse{6}{
\switchtobodyfont[small]
\Test\par}
\stoptext
While the messages appear to be incorrect, there is no apparent problem
associated with them. I do not know if they point to some problem I have
not recognized, or are truly spurious. (And I can eliminate them by
turning off the tracker when I am sure that I have the needed coverage
in the fallbacks.)
Of course, if I am doing something wrong I would like to correct it.
