 C<Hash::Util::FieldHash>, by Anno Siegel, has been added. This module
 provides support for I<field hashes>: hashes that maintain an association
 of a reference with a value, in a thread-safe garbage-collected way.
+Such hashes are useful to implement inside-out objects.

+=head2 Sloppy stat on Windows
+
+On Windows, perl's stat() function normally opens the file to determine
+the link count and update attributes that may have been changed through
+hard links. Setting ${^WIN32_SLOPPY_STAT} to a true value speeds up
+stat() by not performing this operation. (Jan Dubois)

+In previous versions, perl would read the file F</dev/urandom> if it

+to exist on Windows, and if it did would probably not contain appropriate
+data, so perl no longer tries to read it on Windows. (Alex Davies)
