- Reimplemented inode store in separate module chansrv_xfs.[hc] - Allowed atimes and mtimes to be written to Windows side - Mapped file user write bit to (inverted) Windows FILE_ATTRIBUTE_READONLY bit - Mapped file user execute bit to Windows FILE_ATTRIBUTE_SYSTEM bit - Implemented improved security for remotely mounted drives - Implemented USB device removal, allowing hot-plug/remove of memory sticks - Fixed pagefile.sys breaking Ubuntu file browser - Fixed write offset bug - Allowed renaming of open files - Improved reported error codes - Fixed various memory leaks - Addressed valgrind errors related to struct fuse_file_info pointers.
