v1.1.3573.0-Beta

• All storage-specific operations in Virtual File System Sample are now performed in UserFileSystemItem.cs, UserFile.cs and UserFolder.cs files in sample code.
• ETag is deleted together with a file in the user file system. Now ETags are stored in external files. ETags moved/renamed or deleted when a file or folder in remote storage is moved/renamed or deleted.
• Save As in MS Office did not work. Save As in MS Office throw "ETags not equal" exception, because ETag is deleted during MS Office transactional save. Now Save As is supported in MS Office applications.
• Excel temp files synchronized to remote storage. Now excel temp files are not synchronized.

v1.0.0.3019-Alpha

• Synchronization service from the user file system to remote storage is implemented in the Virtual File System sample.
• ETags comparison is refactored and fixed in the Virtual File System Sample. Remote storage ETag and user file system ETag are now compared during the user file system to remote storage upload operation.
• Conflicts between the user file system and the remote storage are now properly processed in the Virtual File System Sample. The conflict icon is displayed in the Windows File Manager. A ConflictException is provided by the Engine.
• If the move or rename operation was performed when the Virtual File System sample was not running, the delete-create sequence occurred in the remote storage (potentially deleting file history and attached data). Now move/rename in remote storage is performed when the app starts, during the synchronization process. 
• MS Office documents saving refactored in the Virtual File System sample. ETags and all custom data on MS Office documents during MS Office transactional save are preserved now.
• MS Office lock file (~$file.docx) detection is fixed and refactored in the Virtual File System Sample.
• When a non-empty folder is deleted in the user file system in the Virtual File System sample, the respective folder deletion failed in remote storage. Now, this bug is fixed.

v1.0.0.2562-Alpha

• File System Engine for Windows with on-demand loading, offline files support, download, and upload progress reporting provided.
• Virtual File System Sample in C# provided. The sample simulates remote storage using a folder in the file system and synchronizes files both from the user file system to remote storage and from remote storage to the user file system.
