+Building C extensions
+---------------------
+
+* The range of possible file names for C extensions has been narrowed.
+ Very rarely used spellings have been suppressed: under POSIX, files
+ named ``xxxmodule.so``, ``xxxmodule.abi3.so`` and
+ ``xxxmodule.cpython-*.so`` are no longer recognized as implementing
+ the ``xxx`` module. If you had been generating such files, you have
+ to switch to the other spellings (i.e., remove the ``module`` string
+ from the file names).
+
+ (implemented in :issue:`14040`.)
