v5.6.15918.0-Beta2

• Context menu on MacOS is now supported.
• New shell extension handler classes provided to run handlers in one process with the Engine: ThumbnailProviderHandlerIntegratedBase, CloudFilesContextMenuVerbIntegratedBase and CustomStateHandlerIntegratedBase classes provided. Virtual Drive and WebDAV Drive Samples updated to run shell extension handlers in one process with the main application.
• ZipFilter is provided. Now zip archiver is supported.
• Microsoft Excel and PowerPoint filters improved.
• Filtering refactored. Now both client to server sync and server to client operations are anow filtered in IEngine.FilterAsync() method.
• Microsoft Office / AutoCAD documents editing is now supported in Virtual File System sample and is supported both in remote storage and in user file system in all samples.
• Lock and Unlock commands in Virtual Drive and WebDAV Drive samples did not refresh status icons in the Windows Explorer. This bug is now fixed.
• ProcessAsync() erronously called IFileSystemItem.DeleteAsync()/MoveToAsync() methods before DeleteCompletionAsync()/MoveToCompletionAsync(). As soon as the delete/move operation can be canceled only if the Engine is running, now the DeleteCompletionAsync()/MoveToCompletionAsync() methods are only called from ProcessAsync().
• Incorrect operation type of OperationType.Delete was passed to FilterAsync() on DeleteCompletionsAsync() call. Now the correct OperationType.DeleteCompletion type is passed.
• The Win32Exception 0x80004005 "The cloud file metadata is corrupt and unreadable" may be thrown if the placeholder did not complete saving. This bug is now fixed.
• Create or update failed. DirectoryNotFoundException "The system can not find the path specified." error may be thrown on delete. This bug is now fixed.
• "Get moved item failed" Win32Exception "The cloud operation is invalid" can be thrown during synchronization. This bug is now fixed.
• Dehydration may throw exceptions if called for new files. This bug is now fixed.
