CHANGES SINCE 2017.1

• 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.]
• Important GitHub issues fixed: #96, #97, #103, #107
