+This is the WinFsp 2017 Release Candidate 1. It has been tested extensively in a variety of scenarios for stability and correct file system semantics. Some of the more important changes:
 
 - API has been polished and finalized.
+- Extensively tested against multiple test suites including Microsoft's IfsTest.
+- WinFsp I/O Queues (the fundamental WinFsp IPC mechanism) have been improved to work similar to I/O Completion Ports.
+- Opportunistic locks have been implemented.
+- File system statistics have been implemented.
 - Sharing a (disk) file system over the network is supported.
 - Case insensitive file systems are supported.
 - Directories are supported as mount points.

 WinFsp is a set of software components for Windows computers that allows the creation of user mode file systems. In this sense it is similar to FUSE (Filesystem in Userspace), which provides the same functionality on UNIX-like computers.
 
-Some of the benefits and features of using WinFsp are listed below:
+Some of the benefits of using WinFsp are listed below:
 
-* Allows for easy development of file systems in user mode. There are no restrictions on what a process can do in order to implement a file system (other than respond in a timely manner to file system requests).
-* Support for disk and network based file systems.
-* Support for NTFS level security and access control.
-* Support for memory mapped files, cached files and the NT cache manager.
-* Support for file change notifications.
-* Support for file locking.
-* Correct NT semantics with respect to file sharing, file deletion and renaming.
+* Very well-tested and stable. Read about its [Testing Strategy](doc/WinFsp-Testing.asciidoc).
+* Very fast. Read about its [Performance](doc/WinFsp-Performance-Testing.asciidoc).
+* Strives for compatibility with NTFS. Read about its [Compatibility](doc/NTFS-Compatibility.asciidoc ).
+* Easy to understand but comprehensive API. Consult the [API Reference](http://www.secfs.net/winfsp/apiref/).
+* FUSE compatibility layer for native Windows and Cygwin. See [fuse.h](inc/fuse/fuse.h).
+* Signed drivers provided on every release.
+* Available under the GPLv3.

 ## How to Help
 
@@ -60,7 +61,7 @@ I am looking for help in the following areas:
 
 * If you have a file system that runs on FUSE please consider porting it to WinFsp. WinFsp has a native API, but it also has a FUSE (high-level) API.
 * If you are working with a language other than C/C++ (e.g. Delphi, C#, etc.) and you are interested in porting/wrapping WinFsp I would love to hear from you.
-* There are a number of outstanding issues listed in the [GitHub repository](https://github.com/billziss-gh/winfsp/issues) ~~[BitBucket repository](https://bitbucket.org/billziss/winfsp/issues?status=new&status=open)~~. Many of these require knowledge of Windows kernel-mode and an understanding of the internals of WinFsp so they are not for the faint of heart. If you decide to tackle any of those please coordinate with me as I am actively working on that issue list.

+= NTFS Compatibility
+
+WinFsp enables the creation of user mode file systems that behave similar to NTFS or FAT. Generic Windows applications that access files on a WinFsp file system cannot and should not be able to determine that it is not a native Windows file system. However specialized applications that access NTFS or FAT specific extensions (such as Defrag) will not work properly on WinFsp file systems.
+
+== Supported features
+
+WinFsp supports the following NTFS features:
+
+- Query and set volume information.
+- Open, create, close, delete files and directories.
+- Query and set file and directory information.
+- Query and set security information (ACL's).
+- Read and write files.

+== Unsupported features
+
+WinFsp does not support the following NTFS features:
+
+- Hard links. Rather rarely used on Windows. However it might be worthwhile to implement them for WinFsp.
+- Extended attributes. Although popular with POSIX file systems, they are severely hampered and rarely used on Windows. They are also not exposed via the Win32 API.
+- Short file names. Short file names are a relic of the past. WinFsp made a conscious decision not to support them.
+- Paging files. Providing paging file support via a user mode file system is impossible for a number of reasons.
+- Object ID's. Opening files by ID (+FILE_OPEN_BY_FILE_ID+) is not supported.
+- Volume access. Volume handles can be opened and closed, but volumes cannot be read or written. Such an operation makes little sense for most user mode file systems, that do not store information on disks.
+- Sparse files. A user mode file system is free to implement sparse files. However WinFsp does not support any sparse file related FSCTL or information class codes.
+- Compressed files. A user mode file system is free to implement compressed files. However WinFsp does not support any compression related FSCTL or information class codes.
+- Encrypted files. A user mode file system is free to implement encrypted files. However WinFsp does not support any encryption related FSCTL or information class codes.
+- Quotas.
+- The Change Journal.
+- Defragmentation support.
+
+== Incompatibilities
+
+This section lists incompatibilites with NTFS in those features that they both support:
+
+- WinFsp supports case sensitive and case insensitive file systems. However it does not support case sensitive lookups on a case insensitive file system (+SL_CASE_SENSITIVE+).
+- NTFS updates the file size information in the directory entry when a file is cleaned up. WinFsp file systems do not (and probably should not attempt to) replicate this behavior. [Related article: https://blogs.msdn.microsoft.com/oldnewthing/20111226-00/?p=8813]
+- NTFS supports change notifications on streams (these are mostly undocumented). WinFsp supports them as well but it differs from NTFS in that it issues a single notification when a file with streams is deleted; NTFS appears to issue one notification per deleted stream.
+- WinFsp does not support renaming a stream.
+- NTFS allows for enumeration and change notifications of all reparse points by opening a special NTFS-only "directory" that "contains" all reparse points (+\$Extend\$Reparse:$R:$INDEX_ALLOCATION+). WinFsp does not support this feature.

+== Compatibility Testing
+
+WinFsp allows the creation of user mode file systems that exhibit behavior similar to NTFS. This means that Windows applications that use such a file system should not be able to tell the difference between NTFS and the WinFsp-based file system. OTOH specialized applications (such as Defrag) will not work properly on WinFsp file systems.

+WinFsp uses the winfsp-tests, winfstest and ifstest test suites for compatibility testing. These test suites verify that WinFsp and NTFS have very similar behavior. There is a separate document that examines the differences between WinFsp and NTFS in more detail.

 == Fault Tolerance Testing
 
 User mode file systems are normal user mode processes and as such they may fail in a variety of conditions. For example, a user mode file system may trigger an access violation while servicing a file operation. As another example, the developer of a user mode file system may terminate the file system process forcefully from within a debugger.

+- FspCleanupDelete -
 An important function of the Cleanup operation is to complete a delete operation. Deleting
 a file or directory in Windows is a three-stage process where the file is first opened, then
 tested to see if the delete can proceed and if the answer is positive the file is then
 deleted during Cleanup.

+     * <li>FspCleanupDelete -
      * An important function of the Cleanup operation is to complete a delete operation. Deleting
      * a file or directory in Windows is a three-stage process where the file is first opened, then
      * tested to see if the delete can proceed and if the answer is positive the file is then
      * deleted during Cleanup.
      *
+     * When this flag is set, this is the last outstanding cleanup for this particular file node.
+     * </li>
+     * <li>FspCleanupSetAllocationSize -
+     * The NTFS and FAT file systems reset a file's allocation size when they receive the last
+     * outstanding cleanup for a particular file node. User mode file systems that implement
+     * allocation size and wish to duplicate the NTFS and FAT behavior can use this flag.
+     * </li>
+     * <li>
+     * FspCleanupSetArchiveBit -
+     * File systems that support the archive bit should set the file node's archive bit when this
+     * flag is set.
+     * </li>
+     * <li>FspCleanupSetLastAccessTime, FspCleanupSetLastWriteTime, FspCleanupSetChangeTime - File
+     * systems should set the corresponding file time when each one of these flags is set. Note that
+     * updating the last access time is expensive and a file system may choose to not implement it.
