NEWS:
Changes from 5.1.1 to 5.2
-------------------------
The new module zsh/param/private can be loaded to allow the shell
to define parameters that are private to a function scope (i.e. are
not propagated to nested functions called within this function).
The parameter flag ${(P)...} is now more useful when it appears in
a nested expansion. For example,
typeset -A assoc=(one un two deux three trois)
name=assoc
print ${${(P)name}[one]}
now prints "un". In previous versions of the shell the value of the
substitution was fully expanded on return from ${(P)name}, making
associative array subscripting difficult. As a side effect, flags
for formatting appearing in the inner substitution now affect the
substitution of the name (into "assoc" in this case), which is not
normally useful: flags that should apply to the value must be in the
outer substitution.
The GLOB_STAR_SHORT option allows the pattern **/* to be shortened to
just ** if no / follows. so **.c searches recursively for a file whose
name has the suffix ".c".
The effect of the WARN_CREATE_GLOBAL option has been significantly
extended, so expect it to cause additional warning messages about
parameters created globally within function scope.

Incompatibilities between 5.1 and 5.2
-------------------------------------
The behaviour of the parameter flag (P) has changed when it appears
in a nested parameter group, in order to make it more useful in
such cases. A (P) in the outermost parameter group behaves as
before. See NEWS for more.
