- 02 Mar 2003 21:24
Changes: In this version, a bug which caused a segfault has been fixed. Several GCC 3.2 build problems have been fixed.
- 03 Feb 2003 01:59
Changes: This release adds a DOS file system filter to imitate DOS 8.3 file names, and a shortname file system filter, to imitate Version 7 Unix 14-character file names. It fixes the segfault bug on Debian, and probably other distros as well, and adds intercepts for the truncate system calls.
- 23 Jan 2003 20:43
Changes: Several build problems have been fixed. A problem has been fixed which caused recent versions of GNU find to work incorrectly. The problem which caused the chroot filter to constantly print an error message has been fixed. A statfs(2) intercept has been added, so the df(1) command is happier. The nocase, upcase, downcase, and titlecase file system filters have been added.
