-v1.4 (2019.2)::
+v1.5B2 (2019.3 B2)::
+
+Changes since v1.4:
+
+* [GEN] WinFsp file systems can now be used by WSLinux. Use the command `sudo mount -t drvfs x: /mnt/x` to mount.
+* [GEN] Extended attribute support has been added for all WinFsp API's: native, .NET, FUSE2 and FUSE3.
+* [FSD] Support for kernel-mode file systems on top of WinFsp has been added. See `FspFsextProvider`. This is in preparation for WinFuse - FUSE for Windows and WSLinux.
+* [FSD] FastIO support has been added. FastIO operations are enabled on cache-enabled file systems with the notable exception of `FastIoQueryOpen`, which allows opening files in kernel mode; this operation requires the file system to specify the `FSP_FSCTL_VOLUME_PARAMS::AllowOpenInKernelMode` flag.
+* [DLL] The `FspFileSystemStartDispatcher` default number of threads (`ThreadCount==0`) has been changed. See commit 3902874ac93fe40685d9761f46a96358ba24f24c for more.
+* [FUSE] FUSE has new `-o UserName=DOMAIN\USERNAME` and `-o GroupName=DOMAIN\GROUPNAME` options. These function like the `-o uid=UID` and `-o gid=GID` options, but accept Windows user and groups names.
+* [FUSE] FUSE has new `-o dothidden` option that is used to add the Windows hidden file attribute to files that start with a dot.
+* [FUSE] FUSE has new `-o create_file_umask=nnn` and `-o create_dir_umask=nnn` options that allow for more control than the `-o create_umask=nnn` option.
+* [.NET] The .NET API now supports asynchronous handling of `Read`, `Write` and `ReadDirectory`. (Thanks @dworkin.)
+* [.NET] The .NET API now supports fine-grained timeouts (`VolumeInfoTimeout`, `DirInfoTimeout`, etc).
+* [.NET] The .NET API has new method `FileSystemHost.MountEx` that adds a `ThreadCount` parameter.
+* [LAUNCH] The Launcher can now rewrite path arguments passed to file systems during launching using "Path Transformation Language". See commit a73f1b95592617ac7484e16c2e642573a4d65644 for more.
+* [FIX] Fixes for very large (> 4GiB) files. (Thanks @dworkin.)
+* [FIX] A fix for how FUSE handles the return value from `opendir`. (GitHub issue billziss-gh/sshfs-win#54)
+* [FIX] A fix for an invalid UID to SID mapping on domains with a lot of users. (Thanks @sganis.)
+* [FIX] A fix on the C++ layer. (Thanks @colatkinson.)
+* Other fixes and improvements.
+
+
+v1.5B1 (2019.3 B1)::
+
+Changes since v1.4:
+
+* Extended attribute support has been added for all WinFsp API's: native, .NET, FUSE2 and FUSE3.
+* Initial FastIO support has been added. FastIO operations are enabled on cache-enabled file systems with the notable exception of `FastIoQueryOpen`, which allows opening files in kernel mode; this operation requires the file system to specify the `FSP_FSCTL_VOLUME_PARAMS::AllowOpenInKernelMode` flag.
+* Fixes for very large (> 4GiB) files. (Thanks @dworkin.)
+* A fix for an invalid UID to SID mapping on domains with a lot of users. (Thanks @sganis.)

 In order to build WinFsp you will need the following:

-* Visual Studio 2015
+* Visual Studio 2015 - 2019
 * Windows Driver Kit (WDK) 10
+    - **NOTE**: When using the latest WDK (Windows 10.0.18362.1) with Visual Studio 2015 you may get an error about a missing task `ValidateNTTargetVersion`. The fix is to edit the file `\Program Files (x86)\Windows Kits\10\build\WindowsDriver.Common.targets` and modify the `UsingTask` line for `ValidateNTTargetVersion` as follows:
+        ```
+        <UsingTask TaskName="ValidateNTTargetVersion" AssemblyFile="$(WDKContentRoot)build\bin\Microsoft.DriverKit.Build.Tasks.16.0.dll"/>
+        ```
 * [Wix toolset](http://wixtoolset.org)

 To fully build WinFsp (including the installer) you must use `tools\build.bat`. By default it builds a Release build, but you can choose either the Debug or Release configuration by using the syntax:

+ * Path Transformation Language
+ *
+ * Syntax:
+ *     PERCENT BACKLASH replace-sep *(*sep component) [*sep UNDERSCORE] arg
+ *
+ * Arg:
+ *     The command line argument that a rule is applied on. These are denoted
+ *     by digits [0-9] or a capital letter (A-Z).
+ *
+ * Component:
+ *     A path component denoted by a small letter (a-z). The letter a denotes
+ *     the first path component, the letter b the second path component, etc.
+ *
+ * UNDERSCORE:
+ *     The UNDERSCORE (_) denotes the "rest of the path". This is any path
+ *     left after any path components explicitly mentioned by using small
+ *     letters (a-z).
+ *
+ * Sep:
+ *     A separator symbol that is used to separated components.
+ *     E.g. slash (/), colon (:), etc.
+ *
+ * Replace-sep:
+ *     A separator symbol that replaces the backslash (\) separator in the
+ *     "rest of the path" (UNDERSCORE). E.g. slash (/), colon (:), etc.
+ *
+ *
+ * Examples:
+ *     - %\/b:_1
+ *         - Transforms \rclone\REMOTE\PATH\TO\FILES to REMOTE:PATH/TO/FILES
+ *     - %\/b:/_1
+ *         - Transforms \rclone\REMOTE\PATH\TO\FILES to REMOTE:/PATH/TO/FILES
+ *     - %\/_1
+ *         - Transforms \P1\P2\P3 to /P1/P2/P3
+ *     - %\+_1
+ *         - Transforms \P1\P2\P3 to +P1+P2+P3
+ *     - %\\_1
+ *         - Transforms \P1\P2\P3 to \\P1\\P2\\P3
+ *         (Backslash is doubled up when used as a replacement separator!)

Felix A. Croes	b350dffe6c	Fix 32 bit overflow issue in FspFsvolReadCached. FspFsvolReadCached takes care not to read beyond the end of the file. However, the offset check uses a 32 bit comparison, which fails for files >= 4G. As a result, reads on a large file will skip blocks at offset (filesize % 4G), and those blocks will zero-filled.	2019-03-07 09:45:42 +01:00
