* Made --hdd mode the default. * Added an --ssd option to select SSD mode. * Added xxHash as an hash function and made it the default. * --hardlink-is-unique no longer forces --hdd mode. * Support for limiting read buffer allocation during scan. * Allow setting verbosity level directly with -V. * Deprecated the --uniques option, it hasn't been useful. * Deprecated the --nodb option, it goes against the dupd way. * Deprecated the --intblocks option, no longer relevant. * Deprecated the --file-count option, not needed. * Various performance improvements. * Minor stats and reporting cleanup. * Add support for building on FreeBSD. * Although not user-visible (ideally), this release contains substantial code refactoring of several subsystems. Test carefully.
