+v1.4B1 (2018.2 B1)::
+
+Changes since v1.3:
+
+* New `Control` file system operation allows sending custom control codes to the file system using the Windows `DeviceIoControl` API.
+
+
+v1.3 (2018.1)::
+
+Changes since v1.2POST1:
+
+* Multiple Launcher changes:
+** New `FspLaunch` API. File systems can be started, stopped, queried and listed using `FspLaunchStart`, `FspLaunchStop`, `FspLaunchGetInfo` and `FspLaunchGetNameList`. The API is available in <winfsp/launch.h>
+** New Launcher registry settings `RunAs` and `WorkDirectory`. `RunAs` allows the laucher to launch a file system process under the service accounts LocalService and NetworkService. `WorkDirectory` can be used to specify the work directory for a newly launched file system process.
+* `FSP_FSCTL_VOLUME_PARAMS::FlushAndPurgeOnCleanup` limits the time that Windows keeps files open after an application has closed them. This purges the cache on the last `CloseHandle`, which is a performance drawback.
+** This is now the default behavior on FUSE. To revert to the previous behavior of keeping files open indefinitely use `-o KeepFileCache`.
+* `FSP_FSCTL_VOLUME_PARAMS` has been extended with fine-grained timeouts: `VolumeInfoTimeout`, `DirInfoTimeout`, `SecurityTimeout`, `StreamInfoTimeout`. Set `FSP_FSCTL_VOLUME_PARAMS::Version == sizeof(FSP_FSCTL_VOLUME_PARAMS)` to access the new fields.
+** New FUSE optons `VolumeInfoTimeout`, `DirInfoTimeout` complement the existing `FileInfoTimeout`.
+* The FSD (File System Driver) and its interaction with the Windows MUP (Multiple UNC Provider) has been changed. In practice this eliminates the delays experienced when right-clicking on a WinFsp-backed network drive in the Windows Explorer. (GitHub issue #87.)
+* The WinFsp network provider is now added first in the provider order list. Previously it was added last. (GitHub PR #131; thanks @felfert.)
+* The WinFsp installer now uses the Wix `Provides` dependency extension to provide a `WinFsp` dependency key. (GitHub PR #129; thanks @felfert.)
+* New FUSE `create_umask` option. (GitHub issue #138.)
+* Fix C++ compilation error for WinFsp-FUSE. (GitHub PR #154; thanks @benrubson.)

+
+
+v1.2POST1 (2017.2; issue #127)::
+
+Changes since v1.1:
+
+- WinFsp-FUSE now supports BSD flags (Windows file attributes) during `getattr` and `fgetattr`. It also adds the `chflags` operation. BSD flags support requires use of the `FSP_FUSE_CAP_STAT_EX` capability and the new `struct fuse_stat_ex` which includes an `st_flags` field. If the preprocessor macro `FSP_FUSE_USE_STAT_EX` is defined before inclusion of `<fuse.h>` then `struct fuse_stat` will also be defined to include the `st_flags` field.
+- WinFsp-FUSE also adds the following OSXFUSE operations: `setcrtime`, `setchgtime`. These can be used to set the creation (birth) time and change (ctime) time of a file.
+- New `GetDirInfoByName` file system operation adds fast queries of directory info by file name rather than pattern [e.g. `FindFirstFileW(L"foobar", FindData)`]. Tests with fsbench showed that such queries are sped up by an order of magnitude when using `GetDirInfoByName` in MEMFS. Case-sensitive FUSE file systems get this optimization for free. The .NET layer also adds `GetDirInfoByName`.
+- New `FspFileSystemOperationProcessId` API adds support for getting the originating process ID (PID) during `Create`, `Open` and `Rename` calls. FUSE file systems can now access `fuse_context::pid`. The .NET layer also adds `GetOperationProcessId`.
+- New command line tool `fsptool` allows command line access to some WinFsp features.
+- The WinFsp launcher now passes the name of the user who launched the file system as a special parameter %U. This is useful to file systems that use the launcher infrastructure, such as SSHFS-Win. [Please note that in earlier betas the user name was passed as parameter %3; the previous method was insecure and is no longer supported.]

-Why is the DLL not installed in the Windows system directories? [@netheril96]::
+Disconnecting (unmapping) a network drive does not work.::
+
+    You may have Dokany installed. Dokany installs its own Network Provider DLL that unfortunately interferes with the WinFsp handling of network drives. The solution is to change your system's Network Provider order and ensure that the WinFsp Network Provider runs before the Dokany one. Instructions on how to change the Network Provider order can be found in this http://blogs.interfacett.com/changing-the-network-provider-order-in-windows-10[article].

+Case-sensitive file systems do not work properly when mounted as a directory.::
+
+    Windows and WinFsp support case-sensitive file systems. These file systems work properly when mounted as a drive. Unfortunately when a file system is mounted as a directory over NTFS, Windows expects it to be case-insensitive and will UPPERCASE many of the file names sent to the file system.
++
+This is an unfortunate but well understood Windows limitation. Case-sensitive file systems should only be mounted as drives.
+
+
+Why is the DLL not installed in the Windows system directories?::
 
     It is true that this would make it convenient to load the DLL, because the Windows loader looks into the Windows system directories when it loads DLL's. However, in the opinion of the WinFsp author, software that does not ship with the OS should not be installing components in the system directories.

 There are a few alternative methods to overcome this problem. WinFsp recommends marking the WinFsp DLL as "delay load" and then using `FspLoad` to dynamically load the DLL during process initialization. For more information see the WinFsp Tutorial.

@@ -49,3 +61,12 @@ With this in mind here are the reasons for the current WinFsp-FUSE behavior:
 - Symmetry with mounting on a drive. On Windows drives are created when the file system comes into existence and deleted when it is gone.
 - Inability to mount over a non-empty directory on Windows. On FUSE/UNIX this is possible, but not on Windows because NTFS disallows the creation of (mountpoint) reparse points on non-empty directories.
 - Most importantly: inability to guarantee that the mount point will cease to exist if the file system crashes. WinFsp attempts to guarantee that all resources used by a file system will get cleaned up. This is certainly true for the kernel-mode FSD, but an attempt is made to do so also in user mode. For this reason, drive symbolic links are marked as temporary and (importantly for our discussion) mount directories are opened with `FILE_FLAG_DELETE_ON_CLOSE`. There is no way to guarantee the removal of a reparse point in the same way.
+
+
+WinFsp-FUSE does not have the ability to support multiple file systems from within the same process. Why?::
+
+    The core WinFsp layer supports multiple file systems in the same process either simultaneously or one after another. However this is not the case with WinFsp-FUSE (i.e. the FUSE layer of WinFsp).
++
+File systems in Windows often need to be run as services. For this reason the WinFsp-FUSE layer provides both file system and Windows service API functionality. This way a WinFsp-FUSE file system can easily become a Windows service. There is a problem: once a Windows process starts acting as a service and then stops being a service, it cannot become a service again.
++
+Having FUSE file systems being able to act as Windows services is valuable. Therefore this is not a limitation that can easily be fixed as FUSE file systems would lose the "free" ability to act as Windows services.

+= Queued Events - Windows kernel events with IOCP scheduling characteristics
+
+In this article I am discussing _Queued Events_. _Queued Events_ are a Windows kernel synchronization mechanism that I invented for https://github.com/billziss-gh/winfsp[WinFsp - FUSE for Windows]. _Queued Events_ behave like kernel Synchronization Events (i.e. Win32 auto-reset events), but provide scheduling characteristics similar to those of I/O Completion Ports.
+
+== The Problem
+
+During the later stages of WinFsp development I decided to do some performance testing to understand its behavior and find opportunities for optimization. I found out that WinFsp performed very well in most tested scenarios, but there was one test that seemed to have bad performance for no particular reason.
+
+I ended up profiling this issue using xperf (included in the https://docs.microsoft.com/en-us/windows-hardware/test/wpt/[Windows Performance Toolkit]), which allows for kernel-level profiling. I spent considerable time looking at the profiling results, but could identify no obvious issue with my code.
+
+After a day or two of doing this and being stumped I finally had a lightbulb moment: what if the issue is not with my code, but with how the OS schedules threads? Sure enough I had xperf trace context switches and found that on good runs the OS would context switch my file system threads relatively rarely; on bad runs the OS would context switch my threads excessively.
+
+After contemplating this issue I realized that this was happening because the OS was trying to schedule my threads in a "fair" manner. Windows in general tries to give every thread a chance to run. This can be counter-productive in server-like programs (such as file systems), where all server threads are equivalent and it is actually better to reuse the same thread (if possible) to avoid context switching and other negative effects.
+
+== The Solution
+
+One way of looking at WinFsp is as an IPC (Inter-Process Communication) mechanism. The Windows kernel packages file system operations (open, close, read, write) as IRP's (I/O Request Packets) which it sends to WinFsp. WinFsp places them in an _I/O Queue_; at a later time the threads in a user mode file system retrieve the IRP's from the _I/O Queue_ and service them.
+
+The _I/O Queue_ had gone through multiple iterations, but at the time I was looking at this issue it was using Windows kernel Synchronization Event's (Win32 auto-reset events) for managing threads. The problem was that a wait on a Synchronization Event would be satisfied in a "fair" manner, thus resulting to excessive context switching and bad performance in some circumstances. I needed to find a way to convince Windows to schedule my threads in an "unfair" manner, giving preference to the same thread as much as possible.
+
+I started considering different schemes where I would associate a different event per thread thus being able to wake up the "correct" thread myself and effectively writing my own mini-scheduler. Luckily I had another lightbulb moment: I/O completion ports already do this better than I would ever be able to!
+
+The kernel portion of an I/O Completion Port is called a https://msdn.microsoft.com/en-us/library/windows/hardware/ff549547(v=vs.85).aspx[KQUEUE]. KQUEUE's are (unfortunately) not directly exposed to user mode, however they are at the core of the user mode I/O Completion Ports. KQUEUE's are the main reason I/O Completion Ports are so fast as they provide the following scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+I briefly considered the idea of building _I/O Queues_ directly on top of KQUEUE's, but soon dismissed this idea because _I/O Queues_ are not simple queues but provide additional services, such as IRP cancelation, IRP expiration, etc.
+
+== Queued Events
+
+In an ideal scenario I wanted to continue using my implementation of _I/O Queues_ which had undergone considerable testing and I knew it worked. But somehow I had to convince the Windows kernel to change the scheduling characteristics of Synchronization Events to mirror those of a KQUEUE.
+
+Then I had lightbulb no 3: _Queued Events_ or how to make a queue behave like a Synchronization Event.
+
+Here is how _Queued Events_ work. A _Queued Event_ consists of a KQUEUE and a spin lock. There is also a single dummy item that can be placed in the KQUEUE.
+
+The KQUEUE is guaranteed to contain either 0 or 1 items. When the KQUEUE contains 0 items the _Queued Event_ is considered non-signaled. When the KQUEUE contains 1 items the _Queued Event_ is considered signaled.

+
+To transition from the non-signaled to the signaled state, we acquire the spin lock and then insert the dummy item in the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549570(v=vs.85).aspx[KeInsertQueue]. To transition from the signaled to the non-signaled state, we simply (wait and) remove the dummy item from the KQUEUE using https://msdn.microsoft.com/en-us/library/windows/hardware/ff549605(v=vs.85).aspx[KeRemoveQueue] (without the use of the spin lock).
+
+----
+EventSet:
+    AcquireSpinLock
+    if (0 == KeReadState())          // if KQUEUE is empty
+        KeInsertQueue(DUMMY);
+    ReleaseSpinLock
+
+EventWait:
+    KeRemoveQueue();                 // (wait and) remove item
+----
+
+First notice that EventSet is serialized by the use of the spin lock. This guarantees that the dummy item can be only inserted ONCE in the KQUEUE and that the only possible signaled state transitions for EventSet are 0->1 and 1->1. This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553253(v=vs.85).aspx[KeSetEvent] works for a Synchronization Event.
+
+Second notice that EventWait is not protected by the spin lock, which means that it can happen at any time including concurrently with EventSet or another EventWait. Notice also that for EventWait the only possible transitions are 1->0 or 0->0 (0->block->0). This is how https://msdn.microsoft.com/en-us/library/windows/hardware/ff553350(v=vs.85).aspx[KeWaitForSingleObject] works for a Synchronization Event.

+endif::env-browser[]
+ifndef::env-browser[image::Queued-Events/transitions.png[]]
+
+We now have to consider what happens when we have one EventSet concurrently with one or more EventWait's:
+
+1. The EventWait(s) happen before https://msdn.microsoft.com/en-us/library/windows/hardware/ff549591(v=vs.85).aspx[KeReadState]. If the KQUEUE has an item one EventWait gets satisfied, otherwise it blocks. In this case KeReadState will read the KQUEUE's state as 0 and KeInsertQueue will insert the dummy item, which will unblock the EventWait.
+2. The EventWait(s) happen after KeReadState, but before KeInsertQueue. If the dummy item was already in the KQUEUE the KeReadState test will fail and KeInsertQueue will not be executed, but EventWait will be satisfied immediately. If the dummy item was not in the KQUEUE the KeReadState will succeed and EventWait will momentarily block until KeInsertQueue releases it.
+3. The EventWait(s) happen after KeInsertQueue. In this case the dummy item in is the KQUEUE already and one EventWait will be satisfied immediately.
+
+NOTE: _Queued Events_ cannot cleanly support an EventClear operation. The obvious choice of using KeRemoveQueue with a 0 timeout is insufficient because it would associate the current thread with the KQUEUE and that is not desirable. KeRundownQueue cannot be used either because it disassociates all threads from the KQUEUE.
+
+The complete implementation of _Queued Events_ within WinFsp can be found here: https://github.com/billziss-gh/winfsp/blob/v1.1/src/sys/driver.h#L655-L795
+
+== Queued Events Scheduling Characteristics
+
+Queued Events encapsulate KQUEUE's and therefore inherit their scheduling characteristics:
+
+- They have a Last-In First-Out (LIFO) wait discipline.
+- They limit the number of threads that can be satisfied concurrently.
+
+These characteristics are desirable because they reduce the number of context switches thus speeding up the WinFsp IPC implementation. Performance testing immediately after the incorporation of _Queued Events_ into WinFsp showed significant performance improvements; profiling with xperf showed that context switches among file system threads were now a relatively rare event!

 One final note regarding security. Notice the `Security` registry value in the example above. This registry value uses SDDL syntax to instruct WinFsp.Launcher to allow Everyone (`WD`) to start (`RP`), stop (`WP`) and get information (`LC`) about the service instance. If the `Security` registry value is missing the default is to allow only LocalSystem and Administrators to control the service instance.

 WinFsp includes a Network Provider that integrates with Windows and can be used to start and stop user mode file systems from the Windows shell. To achieve this the Network Provider (implemented as part of the WinFsp DLL) works closely with the WinFsp.Launcher service.
 
 For example, if a user uses the Windows Explorer to map `\\memfs64\share` to the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to start an instance of the memfs64 service with command line `-i -F NTFS -n 65536 -s 67108864 -u \\memfs64\share -m Z:`. When the user disconnects the `Z:` drive, the Network Provider will instruct the WinFsp.Launcher to stop the previously started instance of the memfs64 service.
+
+== File System Credential Support
+
+Some file systems require credentials in order to allow access and be mounted. Such file systems must add a registry value `Credentials`:
+
+    "Credentials"=dword:00000001
+
+This will instruct the WinFsp Network Provider to request a password from the user prior to starting the file system. This password will then be securely passed to the WinFsp Launcher which in turn will pass it to the user mode file system on its standard input. The user mode file system must respond `OK` if the password is correct and allows access to the user mode file system. Any other response from the user mode file system (including a timeout without a response) is interpreted as an authentication failure.
+
+NOTE: During password entry the user may also choose to "remember" the password in which case it will be saved in the Windows Credential Manager.

-== Compatibility Testing
+== NTFS 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 a tool called fsbench for this purpose. Fsbench is able to test specific scenarios, for example: "how long does it take to delete 1000 files?" Fsbench has been very useful for WinFsp and has helped improve its performance: in one situation it helped identify quadratic behavior with the MEMFS ReadDirectory operation, in another situation it helped fine tune the performance of the WinFsp I/O Queue.
 
+== Backwards Compatibility testing
+
+As the WinFsp API's mature it is important to verify that they remain backwards compatible with existing file system binaries. For this purpose binaries that have been compiled against earlier versions of WinFsp are used to verify that they run correctly against the latest version.
+
+For example, in version v1.2B3 of WinFsp an +FSP_FUSE_CAP_STAT_EX+ FUSE extension was introduced. This can change the layout of +struct fuse_stat+ and is therefore a potentially dangerous change. To test against inadvertent breakage a FUSE file system binary that was compiled against v1.2B2 is regularly used to verify backwards compatibility.
+
 == Code Analysis
 
 WinFsp is regularly run under the Visual Studio's Code Analyzer. Any issues found are examined and if necessary acted upon.
