- Fix: version number shown in jdupes -v wasn't updated in 1.6.1
- Prevent BTRFS dedupe of more files than the kernel can handle
- Track directories to avoid scanning the same directory twice
The directory tracking feature closes a data loss problem that has been around since the early days of fdupes. With the fix, you can specify the same directory more than once (directly on the command line or indirectly by a collision during recursion) and jdupes will always scan it only once. The original problem was that files could be matched with themselves when any directory was specified twice.
NOTICE: This release contains an array overflow bug. Even though this bug is extremely unlikely to cause data loss, the binaries have been deleted as a precaution. Please use the latest binary release instead.
