        2.12.0a2 (2009-04-19)
        ---------------------
        
        Known issues
        ++++++++++++
        
        - Running Zope on Windows is not yet supported in this alpha release.
        More specifically the generated startup scripts need to be adjusted,
        while the code itself should work fine.
        
        - ZODB 3.9.0a12 does not work on Windows with Python 2.6 yet.
        
        - There is no old-style full tarball release that resembles the prior
        releases of Zope at this point.
        
        - easy_install support not fully functional yet.
        
        Restructuring
        +++++++++++++
        
        - If the <permission /> ZCML directive is used to declare a permission that
        does not exist, the permission will now be created automatically, defaulting
        to being granted to the Manager role only. This means it is possible to
        create new permissions using ZCML only. The permission will Permissions that
        already exist will not be changed.
        
        - Using <require set_schema="..." /> or <require set_attributes="..." /> in
        the <class /> directive now emits a warning rather than an error. The
        concept of protecting attribute 'set' does not exist in Zope 2, but it
        should be possible to re-use packages that do declare such protection.
        
        - Updated to Acquisition 2.12.1.
        
        - Updated to DateTime 2.12.0.
        
        - Updated to ZODB 3.9.0a12.
        
        - Removed the `getPackages` wrapper from setup.py which would force all
        versions to an exact requirement. This made it impossible to require
        newer versions of the dependencies. This kind of KGS information needs
        to be expressed in a different way.
        
        - removed `extras_require` section from setup.py (this might possibly
        break legacy code).
        
        Bugs Fixed
        ++++++++++
        
        - Launchpad #348223: optimize catalog query by breaking out early from loop
        over indexes if the result set is already empty.
        
        - Launchpad #344098: in ``skel/etc/zope.conf.ing``, replaced commented-out
        ``read-only-database`` option, which is deprecated, with pointers to the
        appropos sections of ZODB's ``component.xml``.  Updated the description
        of the ``zserver-read-only-mode`` directive to indicate its correct
        semantics (suppressing log / pid / lock files).  Added deprecation to the
        ``read-only-database`` option, which has had no effect since Zope 2.6.
        
        - "Permission tab": correct wrong form parameter for
        the user-permission report
        
        - PageTemplates: Made PreferredCharsetResolver work with new kinds of contexts
        that are not acquisition wrapped.
        
        - Object managers should evaluate to True in a boolean test.
        
        2.12.0a1 (2009-02-26)
        ---------------------
        
        Restructuring
        +++++++++++++
        
        - Switched Products.PageTemplates to directly use zope.i18n.translate and
        removed the GlobalTranslationService hook.
        
        - Removed bridging code from Product.Five for PlacelessTranslationService
        and Localizer. Neither of the two is actually using this anymore.
        
        - Removed the specification of `SOFTWARE_HOME` and `ZOPE_HOME` from the
        standard instance scripts.
        [hannosch]
        
        - Made the specification of `SOFTWARE_HOME` and `ZOPE_HOME` optional. In
        addition `INSTANCE_HOME` is no longer required to run the tests of a
        source checkout of Zope.
        
        - Removed the `test` command from zopectl. The test.py script it was relying
        on does no longer exist.
        
        - Updated to ZODB 3.9.0a11. ZODB-level version support has been
        removed and ZopeUndo now is part of Zope2.
        
        - The Zope2 SVN trunk is now a buildout pulling in all dependencies as
        actual released packages and not SVN externals anymore.
        
        - Make use of the new zope.container and zope.site packages.
        
        - Updated to newer versions of zope packages. Removed long deprecated
        layer and skin ZCML directives.
        
        - Disabled the XML export on the UI level - the export functionality
        however is still available on the Python level.
        
        - No longer show the Help! links in the ZMI, if there is no help
        available. The help system depends on the product registry.
        
        - Updated the quick start page and simplified the standard content.
        The default index_html is now a page template.
        
        - Removed deprecated Draft and Version support from Products.OFSP.
        Also removed version handling from the control panel. Versions are
        no longer supported on the ZODB level.
        
        - Removed left-overs of the deprecated persistent product distribution
        mechanism.
        
        - The persistent product registry is not required for starting Zope
        anymore. `enable-product-installation` can be set to off if you don't
        rely on the functionality provided by the registry.
        
        - ZClasses have been deprecated for two major releases. They have been
        removed in this version of Zope.
        
        - Avoid deprecation warnings for the md5 and sha modules in Python 2.6
        by adding conditional imports for the hashlib module.
        
        - Replaced imports from the 'Globals' module throughout the
        tree with imports from the actual modules;  the 'Globals' module
        was always intended to be an area for shared data, rather than
        a "facade" for imports.  Added zope.deferred.deprecation entries
        to 'Globals' for all symbols / modules previously imported directly.
        
        - Protect against non-existing zope.conf path and products directories.
        This makes it possible to run a Zope instance without a Products or
        lib/python directory.
        
        - Moved exception MountedStorageError from ZODB.POSExceptions
        to Products.TemporaryFolder.mount (now its only client).
        
        - Moved Zope2-specific module, ZODB/Mount.py, to
        Products/TemporaryFolder/mount.py (its only client is
        Products/TemporaryFolder/TemporaryFolder.py).
        
        - Removed spurious import-time dependencies from
        Products/ZODBMountPoint/MountedObject.py.
        
        - Removed Examples.zexp from the skeleton. The TTW shopping cart isn't
        any good example of Zope usage anymore.
        
        - Removed deprecated ZTUtil.Iterator module
        
        - Removed deprecated StructuredText module
        
        - Removed deprecated TAL module
        
        - Removed deprecated modules from Products.PageTemplates.
        
        - Removed deprecated ZCML directives from Five including the whole
        Five.site subpackage.
        
        Features added
        ++++++++++++++
        
        - OFS.ObjectManager now fully implements the zope.container.IContainer
        interface. For the last Zope2 releases it already claimed to implement the
        interface, but didn't actually full-fill the interface contract. This means
        you can start using more commonly used Python idioms to access objects inside
        object managers. Complete dictionary-like access and container methods
        including iteration are now supported. For each class derived from
        ObjectManager you can use for any instance om: `om.keys()` instead of
        `om.objectIds()`, `om.values()` instead of `om.objectValues()`, but also
        `om.items()`, `ob.get('id')`, `ob['id']`, `'id' in om`, `iter(om)`,
        `len(om)`, `om['id'] = object()` instead of `om._setObject('id', object())`
        and `del ob['id']`. Should contained items of the object manager have ids
        equal to any of the new method names, the objects will override the method,
        as expected in Acquisition enabled types. Adding new objects into object
        managers by those new names will no longer work, though. The added methods
        call the already existing methods internally, so if a derived type overwrote
        those, the new interface will provide the same functionality.
        
        - Acquisition has been made aware of `__parent__` pointers. This allows
        direct access to many Zope 3 classes without the need to mixin
        Acquisition base classes for the security to work.
        
        - MailHost: now uses zope.sendmail for delivering the mail. With this
        change MailHost integrates with the Zope transaction system (avoids
        sending dupe emails in case of conflict errors). In addition
        MailHost now provides support for asynchronous mail delivery. The
        'Use queue' configuration option will create a mail queue on the
        filesystem (under 'Queue directory') and start a queue thread that
        checks the queue every three seconds. This decouples the sending of
        mail from its delivery.  In addition MailHosts now supports
        encrypted connections through TLS/SSL.
        
        - SiteErrorLog now includes the entry id in the information copied to
        the event log. This allowes you to correlate a user error report with
        the event log after a restart, or let's you find the REQUEST
        information in the SiteErrorLog when looking at a traceback in the
        event log.
        
        Bugs Fixed
        ++++++++++
        
        - Launchpad #332168: Connection.py: do not expose DB connection strings
        through exceptions
        
        - Specified height/width of icons in ZMI listings so the table doesn't
        jump around while loading.
        
        - After the proper introduction of parent-pointers, it's now
        wrong to acquisition-wrap content providers. We will now use
        the "classic" content provider expression from Zope 3.
        
        - Ported c69896 to Five. This fix makes it possible to provide a
        template using Python, and not have it being set to `None` by
        the viewlet manager directive.
        
        - Made Five.testbrowser compatible with mechanize 0.1.7b.
        
        - Launchpad #280334: Fixed problem with 'timeout'
        argument/attribute missing in testbrowser tests.
        
        - Launchpad #267834: proper separation of HTTP header fields
        using CRLF as requested by RFC 2616.
        
        - Launchpad #257276: fix for possible denial-of-service attack
        in PythonScript when passing an arbitrary module to the encode()
        or decode() of strings.
        
        - Launchpad #257269: 'raise SystemExit' with a PythonScript could shutdown
        a complete Zope instance
        
        - Switch to branch of 'zope.testbrowser' external which suppresses
        over-the-wire tests.
        
        - Launchpad #143902: Fixed App.ImageFile to use a stream iterator to
        output the file. Avoid loading the file content when guessing the
        mimetype and only load the first 1024 bytes of the file when it cannot
        be guessed from the filename.
        
        - Changed PageTemplateFile not to load the file contents on Zope startup
        anymore but on first access instead. This brings them inline with the
        zope.pagetemplate version and speeds up Zope startup.
        
        - Collector #2278: form ':record' objects did not implement enough
        of the mapping protocol.
        
        - "version.txt" file was being written to the wrong place by the
        Makefile, causing Zope to report "unreleased version" even for
        released versions.
        
        - Five.browser.metaconfigure.page didn't protect names from interface
        superclasses (http://www.zope.org/Collectors/Zope/2333)
        
        - DAV: litmus "notowner_modify" tests warn during a MOVE request
        because we returned "412 Precondition Failed" instead of "423
        Locked" when the resource attempting to be moved was itself
        locked.  Fixed by changing Resource.Resource.MOVE to raise the
        correct error.
        
        - DAV: litmus props tests 19: propvalnspace and 20:
        propwformed were failing because Zope did not strip off the
        xmlns: attribute attached to XML property values.  We now strip
        off all attributes that look like xmlns declarations.
        
        - DAV: When a client attempted to unlock a resource with a token
        that the resource hadn't been locked with, in the past we
        returned a 204 response.  This was incorrect.  The "correct"
        behavior is to do what mod_dav does, which is return a '400
        Bad Request' error.  This was caught by litmus
        locks.notowner_lock test #10.  See
        http://lists.w3.org/Archives/Public/w3c-dist-auth/2001JanMar/0099.html
        for further rationale.
        
        - When Zope properties were set via DAV in the "null" namespace
        (xmlns="") a subsequent PROPFIND for the property would cause the
        XML representation for that property to show a namespace of
        xmlns="None".  Fixed within OFS.PropertySheets.dav__propstat.
        
        - integrated theuni's additional test from 2.11 (see r73132)
        
        - Relaxed requirements for context of
        Products.Five.browser.pagetemplatefile.ZopeTwoPageTemplateFile,
        to reduce barriers for testing renderability of views which
        use them.
        (http://www.zope.org/Collectors/Zope/2327)
        
        - PluginIndexes: Fixed 'parseIndexRequest' for false values.
        
        - Collector #2263: 'field2ulines' did not convert empty string
        correctly.
        
        - Collector #2198: Zope 3.3 fix breaks Five 1.5 test_getNextUtility
        
        - Prevent ZPublisher from insering incorrect <base/> tags into the
        headers of plain html files served from Zope3 resource directories.
        
        - Changed the condition checking for setting status of
        HTTPResponse from to account for new-style classes.
        
        - The Wrapper_compare function from tp_compare to tp_richcompare.
        Also another function Wrapper_richcompare is added.
        
        - The doc test has been slightly changed in ZPublisher to get
        the error message extracted correctly.
        
        - The changes made in Acquisition.c in Implicit Acquisition
        comparison made avail to Explicit Acquisition comparison also.
        
        - zopedoctest no longer breaks if the URL contains more than one
        question mark. It broke even when the second question mark was
        correctly quoted.
        
        Other Changes
        +++++++++++++
        
        - Added lib/python/webdav/litmus-results.txt explaining current
        test results from the litmus WebDAV torture test.
        
        - DocumentTemplate.DT_Var.newline_to_br(): Simpler, faster
        implementation.
