• Custom columns data was erased when setting the file icon. Now custom data is stored in the external file in the data folder, separately for each file. Custom columns implementation is moved to a new Virtual Drive sample.
• Files and folders are now only marked as modified when file content is modified or the folder is moved. The StorageProviderSyncRootInfo.InSyncPolicy is now set to StorageProviderInSyncPolicy.Default in Registrar class in samples.
• New files are now converted to a placeholder only after successful file upload in the sample code.
• File comparison changed in Virtual Drive and User File System samples. Instead of ETag-LastModifiedDate now file hashes are computed.
