+# Changelog
+
+
+## v1.11B2 (2022+ARM64 Beta2)
+
+- [NEW] ARM64 support! For details see [WinFsp on ARM64](https://github.com/winfsp/winfsp/wiki/WinFsp-on-ARM64).
+
+- [NEW] A new file system operation has been added to the FUSE API:
+
+    ```C
+    int (*getpath)(const char *path, char *buf, size_t size,
+        struct fuse_file_info *fi);
+    ```
+
+    The `getpath` operation allows a case-insensitive file system to report the correct case of a file path. For example, `getpath` can be used to report that the actual path of a file opened as `/PATH/TO/FILE` is really `/Path/To/File`. This capability is important for some Windows file system scenarios and can sometimes result in a performance improvement.
+
+- [NEW] Many performance improvements:
+
+    - A new `PostDispositionForDirOnly` setting has been added to `FSP_FSCTL_VOLUME_PARAMS`. This allows a file system to declare that it does not want to see `SetInformation/Disposition` requests for files (such requests will still be sent for directories, because a file system is supposed to check if a directory is empty before deletion). This makes file (not directory) deletion faster. This optimization should be safe to enable for most file systems. FUSE file systems get this optimization for free.
+
+    - The FSD now implements "fast I/O" reads and writes. Fast I/O is a technique for doing I/O without using IRP's (I/O Request Packets) and can only work for file systems using the cache manager (`FileInfoTimeout==-1`). This results in significant improvement in read/write scenarios.
+
+    - The FSD per directory cache limit has been increased from 16K to 64K. This should allow for more directory data to be maintained in kernel and reduce round-trips to a user mode file system.
+
+    - The user mode directory buffering mechanism (`FspFileSystemAcquireDirectoryBuffer`) has been improved. The mechanism uses the quick-sort algorithm internally which can exhibit bad performance when sorting already sorted data. The quick-sort algorithm has been improved with the use use of median of three partitioning, which alleviates this problem.
+
+- [NEW] The default value for the registry setting `DistinctPermsForSameOwnerGroup` has been changed from 0 to 1.
+
+- [NEW] New `ntptfs` sample file system. This is a production quality pass through file system and should be used instead of the original `passthrough` file system that was developed for education purposes only.
+
+- [FIX] The WinFsp Network Provider now implements `NPGetUniversalName`. This fixes problems with some apps (e.g. Photos app).
+
+- [BUILD] Product configuration (`MyProductName`, etc.) is done by the file `build.version.props` located in `build\VStudio`. This file was previously named `version.properties`.
+
+
+## v1.11B1 (2022+ARM64 Beta1)
+
+- [NEW] ARM64 support! For details see [WinFsp on ARM64](https://github.com/winfsp/winfsp/wiki/WinFsp-on-ARM64).

+= WinFsp on ARM64
+
+This document summarizes the changes made to WinFsp to support Windows on ARM64. With these changes WinFsp runs natively in the ARM64 environment, while maintaining backwards compatibility.
+
+== Build System
+
+* Visual Studio 2019 or later is required to build WinFsp. Visual Studio 2015 builds are no longer possible because of lack of ARM64 support.
+** The script `tools\gensrc\remove-build-arm64.bat` can be used to remove the ARM64 configuration from the project files. This allows WinFsp to be built with Visual Studio 2015, but without ARM64 support. This is a hack to support AppVeyor builds on Server 2012 images that have only Visual Studio 2015 installed.
+* Build configuration is now done by the file `build.common.props` located in `build\VStudio`.
+* Product configuration (`MyProductName`, etc.) is done by the file `build.version.props` located in `build\VStudio`. This file was previously named `version.properties`.
+* Project files under `build\VStudio` have been updated to support ARM64 builds.
+
+== Include Files
+
+* The macros `FSP_FSCTL_PRODUCT_FULL_REGKEY` and `FSP_FSCTL_PRODUCT_FILE_ARCH` have been added to header file `inc\winfsp\fsctl.h`:
+** `FSP_FSCTL_PRODUCT_FULL_REGKEY`: The full registry path for WinFsp.
+** `FSP_FSCTL_PRODUCT_FILE_ARCH`: The expected computer architecture suffix to use for file names (`a64` for ARM64, `x64` for x64, `x86` for x86).
+
+== File System Driver
+
+* The `IoInitializeTimer`, `IoStartTimer` and `IoStopTimer` DDI's are missing from Windows on ARM64 (https://social.msdn.microsoft.com/Forums/en-US/e1f4dbbd-a3f1-40a4-8f8b-e12a04b1b074/is-iostarttimer-universal[link]). The same functionality is now implemented within WinFsp in file `src\sys\devtimer.c`
+* The FSD (and other WinFsp components) used a number of memory barriers primarily for the purpose of lock-free access of certain variables. Most of these memory barriers have been removed and replaced with "interlocked" loads/stores so that any such accesses would continue to be correct under ARM64, which has weaker consistency guarantees than x86/x64. The new `FspInterlocked*` calls are implemented in `inc/winfsp/fsctl.h` and are used by both kernel and user mode code.
+
+== Samples
+
+* The sample project files have been updated to support ARM64 builds.
+
+== Installer
+
+* The installer has been retrofitted to support native installation on ARM64, x64 and x86 environments.
+* The installer remains a single MSI file that supports all architectures.
+** NOTE: The current technique for detecting OS architecture relies on reading the registry value `PROCESSOR_ARCHITECTURE` from key `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment`. This may be fragile and a better technique may be required.
+* Files are installed in `\Program Files (x86)\WinFsp` on ARM64 and x64 Windows and `\Program Files` on x86 Windows.
+* Registry settings are placed in `HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\WinFsp` on ARM64 and x64 Windows and `HKEY_LOCAL_MACHINE\SOFTWARE\WinFsp` on x86 Windows.
+* Files for all architectures are always installed regardless of OS architecture. For example, all of `winfsp-a64.dll`, `winfsp-x64.dll` and `winfsp-x86.dll` are found in the `bin` subdirectory on ARM64, x64 and x86 Windows.
+* WinFsp supports x86 file systems on x86 Windows, x86 and x64 file systems on x64 Windows and x86, x64 and ARM64 file systems on ARM64 Windows.
+
+== License
+
+* The special exception for FLOSS to GPLv3 has been updated to mention that linking to `winfsp-a64.dll` is also allowed.

+v1.10 (2022)::
+
+Changes since v1.9:
+
+* [NEW] Official Windows 11 support.
+
+* [NEW] Support for `FileDispositionInformationEx` and `FileRenameInformationEx` has been added. Native and .NET file systems must enable this support by setting `SupportsPosixUnlinkRename` in `FSP_FSCTL_VOLUME_PARAMS`. FUSE file systems have this support enabled by default, but they can disable it by using the `-o LegacyUnlinkRename` command line option.
+
+* [NEW] WinFsp now supports rebranding of the build products. This is primarily useful to commercial licensees. See https://github.com/billziss-gh/winfsp/wiki/WinFsp-Rebranding for more information.
+
+* [NEW] WinFsp-FUSE has a new capability `FSP_FUSE_CAP_DELETE_ACCESS`. If this capability is specified WinFsp will call the FUSE `access` method with the WinFsp-specific flag `FSP_FUSE_DELETE_OK` to check whether the deletion should be allowed. This can be used to disallow deletion of files and directories that would normally be allowed under the FUSE/POSIX model.
+
+* [NEW] WinFsp-FUSE has a new method for determining file access in the case where the user's primary SID (Windows Security Identifier) and group SID are the same (for example, this can happen when someone uses a Microsoft account as their primary login).
+** Previously when the user SID and group SID were the same WinFsp-FUSE looked at the UNIX permissions for the owner and the UNIX permissions for the group and used the MOST restrictive permissions, which often resulted in inadvertent "access denied" errors. (For example, if the owner permission was `rw-` and the group permission was `---` the result was `---` and therefore access denied).
+** Going forward this behavior will change. The user and group mode permissions will not be considered together even in the case where the user SID and group SID are the same. This will resolve the access denied errors.
+** However to preserve backward compatibility (there might be some file systems that rely on the old behavior) we will do so in stages. For release v1.10 (2021.1) there is a new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `DistinctPermsForSameOwnerGroup`, which if set to 1 will direct WinFsp-FUSE to use the new behavior. The default value is 0 which directs WinFsp-FUSE to use the old behavior. This default will change in a future release.
+
+* [NEW] A new registry setting under `HKLM\SOFTWARE\WinFsp` (or `HKLM\SOFTWARE\WOW6432Node\WinFsp` on a 64-bit system) called `MountDoNotUseLauncher` has been introduced, which if set to 1 will disable the use of the Launcher during mounting. The default value is 0 which allows the use of the Launcher during mounting in those rare cases when necessary. (In general the Launcher is not necessary for mounting. However when running a file system in the Windows Service context (session 0) under an account that is not LocalSystem (e.g. `NT AUTHORITY\NETWORK SERVICE`), the Launcher is used to create global drives.)
+
+* [NEW] A new sample memfs-fuse file system written in C++ has been added. This file system uses all FUSE2 features offered by WinFsp-FUSE, passes all file system tests (that can be passed by a FUSE2 file system) and will act as the reference WinFsp-FUSE file system going forward.
+
+* [FIX] Fixed a problem with `FspFileSystemReadDirectoryBuffer` and file systems that support pattern matching (like passthrough). (GitHub issue #351.)
+
+* [FIX] File share access when overwriting a file (e.g. when using `TRUNCATE_EXISTING`) is now done in a manner compatible with NTFS (previously there were cases when overwriting a file where behavior diverged from the NTFS one). (See GitHub issue #364.)
+
+* [FIX] The FSD will now report a file's reparse tag in the `EaSize` field of `FILE_FULL_DIR_INFORMATION` and friends. This fixes problems such as `cmd.exe` not recognizing symlinks in a `dir` command. (See GitHub issue #380.)
+
+* [FIX] Fixed a problem in the file system shutdown protocol which resolves an occasional access violation in the user mode file system process. Previously it was possible for a file system to crash when stopping itself using `FspFileSystemStopDispatcher`; this problem has been rectified. (See GitHub issue #369.)
+
+* [FIX] Improved symlink support for FUSE file systems. Notably:
+
+** FUSE file systems now support converting a directory to a symlink reparse point.
+
+** The determination of whether a symlink is a file or directory (necessary because the Windows file system makes this distinction) is now possible for file systems that do not support slashdot (`/.`) queries. (A slashdot query is one like `getattr("/PATH/.")`; such queries are not normally expected to be resolved by FUSE file systems.)
+
+* [FIX] Fixed a problem in the FUSE layer where in some rare circumstances the `release` operation could be called with an uninitialized `path` argument. (See GitHub issue billziss-gh/cgofuse#58 and commit f51bdef53427d1bba688fb6c768792fdc22ffc7b).
+
+* [FIX] Fixed a potential problem when launching file system instances using the Launcher. (See GitHub issue #356.)
+
+* [FIX] The `winfsp.h` header no longer defines `FILE_FULL_EA_INFORMATION` when compiled under mingw. This is because the mingw tool chain already includes a definition of this type. (GitHub PR #371. Thanks @ lemourin.)
