Version 6.1

The use of delegates has been tuned down in favor of completion handlers. Some methods have been deprecated and replaced as a result. Others have been improved.

Breaking Changes
Multiple delegate methods have been deprecated. As a result many method names have been changed and others have been completely deprecated. Old methods that have been changed are marked as deprecated using the __deprecated flag and in the documentation.

The uploadLocalOfflineDocumentsWithDelegate method no longer prevents sqlite files from being uploaded - now only hidden files aren't uploaded. The functionality of file conflicts and file conflict handling has also changed.

Other Changes

• The iCloudError delegate method has been replaced with completion blocks. Some completion blocks now contain an NSError parameter which will contain information about any errors that may occur during a file operation.
• A new delegate method has been added to handle file conflicts.
• Three methods have been deprecated in favor of newer methods that provide more information using completion handlers rather than delegates.
• The new method, uploadLocalOfflineDocumentsWithDelegate, has undergone numerous improvements. File conflict handling during upload is now supported - conflicts are automatically delt with. If a conflict cannot be resolved, the new iCloudFileUploadConflictWithCloudFile:andLocalFile: delegate method is called. This method no longer prevents sqlite files from being uploaded - now only hidden files aren't uploaded.
• Major documentation improvements to both the DocSet and the Readme.
