Version CVS

  - ConflictError was swallowed by _delObject. This could break code
    expecting to do cleanups before deletion.

  - Renamed hasObject() to has_key().  hasObject() conflicted with
    another product.

  - You can now visit objects whose names have a trailing space.

Version 1.0

  - BTreeFolder2s now use an icon contributed by Chris Withers.

  - Since recent ZODB releases have caused minor corruption in BTrees,
    there is now a manage_cleanup method for fixing damaged BTrees
    contained in BTreeFolders.

Version 0.5.1

  - Fixed the CMFBTreeFolder constructor.
