================

- Bug fix to load ZCML for GS when Products.GenericSetup is installed.
[aclark]

================

- Added the GenericSetup import context as an annotation to the transmogrifier.
[elro]

- Added a logger to log the value of a particular key for all items. Handy
when debugging, you can see which path is failing, and good if you want
to show progress in a long import.
[regebro]

- Added a breakpoint section to break on a particular expression, which is
handy for debugging.

================

- Bug fix: the constructor promises to encode paths to ASCII, but failed to
do so. Thanks to gyst for finding the discrepancy.

================

- Allow the CSV source to load its file from a package as well as from an
absolute or relative file path. To load from a package, pass
``package.name:filename.csv`` to the ``filename`` option.
[optilude]

- Add CMF 2.2/Plone 4 compatibility for the content constructor
[optilude]

- Use an explicit provides attribute to register the transmogrifier adapter.
Fixes the "Missing 'provides' attribute" errors when loading with
zope.annotation installed.
[mj]

- Add a required flag to the content constructor, which causes it to raise
a KeyError if the container where to construct the new item doesn't exist.
[regebro]

- Add an optional condition to the manipulator section.

================
