Changelog for 1.5.0b1
- ---------------------

- - LP #388380:  removed obsolute STX docs from the package
  directory.

- - Made export / import features for old-school TextIndex (removed
  in Zope 2.12) conditional.

- - Added support for import / export of subscribers from component
  registry.

- - Adapter removal.

- - Fix utility removal so utility is not added when it is missing
  from the local component registry.

- - Fixed component handler to use 'for' not 'for_' in adapter
  directive. To support import of existing profiles 'for_' is
  used as a fallback.

- - Changed testing.py to directly load zope.traversing's ZCML
  instead of going via the Five traversing.zcml BBB shim.

- - Added new feature to the component handler. For factory based
  utilities you can now specify an additional id. All factory
  based utilities will now by default be added to the site
  manager (being an ObjectManager itself) as an object and this
  persistent object is registered as the utility. On removal both
  the registration and the object are removed. The new id
  argument is used to specify the id of the object as set via
  `__name__`. This change makes these utilities introspectable in
  the ZMI and clearly separates the persistent object and utility
  registration aspect.

- - Adjusted TarballImportContext to work with Python 2.6's tarfile
  module.

- - Cleaned up / normalized imports:

  o Don't import from Globals;  instead, use real locations.

  o Make other imports use the actual source module, rather than
  an intermediate (e.g., prefer importing 'ClassSecurityInfo'
  from 'AccessControl.SecurityInfo' rather than from
  'AccessControl').

  o Avoid relative imports, which will break in later versions of
  Python.

- - events: Added 'handleProfileImportedEvent' subscriber.  After a
  full import it updates 'last version for profile'.

- - UpgradeSteps: Improved listUpgradeSteps behavior.  If versions
  and checker are specified for a step, the checker is used as an
  additional restriction.

- - Don't fail when a sub-item cannot be adapted after creation
  when importing a folder.

- - Avoid even an explicit purge of the rolemap if no XML file is
  present in a given context.
  (https://bugs.launchpad.net/zope-cmf/+bug/279294)

- - Component registry import: Add the ability to unregister a
  component by specifying the "remove" attribute inside a utility
  node.  (https://bugs.launchpad.net/zope-cmf/+bug/161728)

- - Property import/export tests: Add testing for non-ASCII
  properties.  (https://bugs.launchpad.net/zope-cmf/+bug/202356)
  (https://bugs.launchpad.net/zope-cmf/+bug/242588)

- - Add 'IChunkedImportContext' interface, allowing RAM-efficient
  chunked reads of large files, and implement for
  'DirectoryImportContext'.
  (https://bugs.launchpad.net/zope-cmf/+bug/259233)

- - Add <genericsetup:upgradeDepends> ZCML tag; defines a
  specialized upgrade step that re-applies one or more import
  steps from a GS profile during an upgrade process

- - Add 'IChunkedExportContext' interface, allowing RAM-efficient
  chunked writes of large files, and implement for
  'DirectoryExportContext'.
  (https://bugs.launchpad.net/zope-cmf/+bug/257365)

- - Provide default for dependencies when processing metadata.xml,
  to avoid a KeyError.
  (https://bugs.launchpad.net/zope-cmf/+bug/255301)

- - Handle utility factories cleanly if zope.component >=3.5.0 is
  used.

- - tool and utils: Removed deprecated code.

- - Update PropertyManagerHelpers to make it possible to remove
  elements from a property by adding a remove="True" attribute to
  the element. This can also be used to reorder elements since
  new elements are always added at the end of the list.

- - Made PropertyManagerHelpers class work for non-PropertyManager
  objects

  o Derived classes can supply a '_PROPERTIES' scehma, which is
  then used to mock up a temporary propertysheet for the object.
  The adapter's methods ('_extractProperties',
  '_purgeProperties', '_initProperties') then run against that
  propertysheet.

- - Added logic to respect the destination of upgrade steps when
  determining their applicability.

- - Enhanced the readability of the upgrades tab on the tool.

- - Changed upgrade logic to set the current version after an
  upgrade to the destination version of the last step run,
  instead of the current profile version.

- - Use the parse_version function from pkg_resources to normalize
  versions before comparing them inside the upgrade code. This
  ensures pre-release versions are handled correctly. Also use
  the normalize code when sorting versions on the tools ZMI
  upgrades page.

- - Fixed the upgrade step directive schema. Description is not
  required.

- - Introduced a new IComponentsHandlerBlacklist interface. You can
  register named utilities for it and provide sequences of
  interfaces which should not be handled by the standard
  components registry adapter. This allows more specialized
  export/import handlers to take full control over the components
  they care about.

- - When loading multiple profiles reload the list of steps to use
  after each import.
