Version 5.2 of zsh has been released and is available at
http://www.zsh.org/pub/ with uploads to Sourceforge to follow.

This has a lot of bug fixes and fewer minro [minor] feature additions.
See the README file.

As before, there are .gz and .xz compressed versions.  In addition,
all tar files have detached gpg signatures in .asc files signed with the key

Version
-------

This is version 5.2 of the shell.  This is a stable release.  There are
a few visible improvements since 5.1.1 as well as many bugfixes.  Note
in particular the changs [changes] highlighted under "Incompatibilites
[Incompatibilities] between 5.1 and 5.2" below.  See NEWS for more
information.

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.

CHANGES FROM PREVIOUS VERSIONS OF ZSH
-------------------------------------

Note also the list of incompatibilities in the README file.

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.
