My modules are not read anymore, allthough Context thinks it does. This must have been the case for some time. I ran a test with an older version which demonstrates that the change in behaviour must have occurred after january second.
Minimal example follows.

Hans van der Meer

Module code in file module-test is:
\writestatus{HVDM}{Module has been read}
\endinput

Test code in file moduletest.tex is:
\usemodule[module-test]
\starttext
module testing look into the log.
\stoptext

In the log I find:

This is LuaTeX, Version beta-0.79.1 (TeX Live 2014/dev) (rev 4972) 
 \write18 enabled.

ConTeXt  ver: 2014.06.05 23:04 MKIV beta  fmt: 2014.6.6  int: english/english

open source     > 2 > 3 > /Users/hansm/tex/test-tex/modules/moduletest.tex
resolvers       > modules > 'module-test' is already loaded          <-- wrongly thinks it is loaded

It says the module is already loaded, but the telltale \writestatus is absent.

Running the same code with an older version of ConTeXt does load the module:

ConTeXt  ver: 2014.01.02 20:05 MKIV current  fmt: 2014.1.2  int: english/english
(/Users/hansm/tex/test-tex/modules/moduletest.tex
resolvers       > modules > 'module-test' is loaded                 <-- loads as it should
(module-test.tex
HVDM            > Module has been read
