objects since the value of their str() is not part of their API, and can
vary between releases.

Update AccessControl package to deal with various forms of Unicode and add some tests to make sure.  This fixes Collector #1034.

Continuing on #572. manage_DAVget is now used from the WebDAV source port as well as the standard HTTP port.

prefix while using Expat in namespace mode; this violates the "Prefix
Declared" namespace constraint.  Expat 1.95.7 now checks this
constraint properly, so raises an exception.

  with the revived CVS key management system.

     - Workaround for Collector #1081: The 'title' property for objects
       derived from OFS.Folder or PropertyManager can now be
       removed and replaced with a ustring property. This allows the usage
       of non-ISO-8859-1 or ASCII charsets

and replaced with a ustring property

Two new methods have been added to WebDAV resources, "manage_DAVget"
and "listDAVObjects". These are now used by WebDAV instead of the
earlier "manage_FTPget" and "objectValues". This separates the
permissions, and allows WebDAV specific overriding of these methods.

Make 'publisher-profile-file' configuration file setting work.  Note that the environment variable "PROFILE_PUBLISHER" has been banished with this change.  We also change the core of Publish.py to not conditionally define functions in order to have a bit more control over the process.

- rearranged order

     - Collector #951: DateTime(None) is now equal to DateTime()

     - Collector #951: DateTime(None) now raises a proper SyntaxError

       in the Zope Book.

flattenInterfaces now walks recursivly into tuples. Tuples are used if the __implements__ declaration is like (IFoo.__implements__, IBar)

some Zope products.

- Fixed BaseRequest's traversal loop. (Collector #1079)

Fix after namespace issue fix.  Because 'action' always exists in a manage_options entry for an item, its existence in the entry is not a reliable indicator that the entry is not the "View" tab.  Since it was tested for by "has_key", the View tab always pointed back to the current page (manage_workspace).  We fix it here by using "get" instead of "has_key".

Revert feature of never updaing metadata if index is specified in catalog_object.  This broke several applications.  Instead, we provide the catalog_object method (and the Catalog.py's catalogObject method) with an update_metadata keyword argument.  If the update_metadata keyword argument is set false (the default is true), metadata is not updated.
