Date Modules Changes
2011-05-02 exit The module is removed. It was deprecated
on 2010-03-05. Use 'stdlib' directly instead.
2011-04-27 mgetgroups The 'xgetgroups' function has been split into
a new 'xgetgroups' module.
2011-04-27 save-cwd This module pulls in fewer dependencies by
default; to retain robust handling of directories
with an absolute name longer than PATH_MAX, you
must now explicitly include the 'getcwd' module.
2011-04-19 close-hook This module has been renamed to 'fd-hook' and
generalized.
2011-03-08 regex-quote The last argument is no longer an 'int cflags'
but instead a pointer to a previously constructed
'struct regex_quote_spec'.
