Release Notes: The predetermined limit on catalog size has been removed. XFS is used instead of ext2: the advantage is total inodability and easier calculation of growing amounts, while the disadvantage is the inability to shrink the filesystem. The preemptively huge image approach was discarded in favor of dynamic growing: the number of inodes needed is grossly guessed at addition time and the catalog is grown as needed. mkindex.sh was cleaned up (moving virtualcopy to a inner function, which also improved performance). trxclean.sh was added to clean the mount database.
