Release Notes: This release brings a few minor cleanups (messages) and one feature: it now has a mode where the output file/partition/disk is overwritten two (-3) or three (-4) times with random data and finally with zeros. This supports secure data destruction according to German data privacy standards from BSI.
Release Notes: This version includes a plugin interface (that allows analysis or transformation of data prior to being written) an MD5 plugin, the use of posix_fadvise(), and the output of only short usage info on incorrect input parameters.
Release Notes: Refactoring allows for better runtime and build time feature detection, resulting in support for building against Android (NDK) and in fast AVX2 sparse block detection. This version also brings a new option -u/--rmvtrim that removes a written (typically zero-filled) file again after completion and issuing an fstrim operation.
Release Notes: The -p/--preserve option now also copies extended attributes (including ACLs) if there are any. Many checks and test cases have been added to make check. Half-empty blocks are now detected now in sparse detection. If copying with an odd file offset, the odd-sized write will be done first so that further accesses should be better aligned, which should help with performance (and optionally sparse detection).
Release Notes: The main change is a fix for a bug where the last block could have appended zeros if hardbs==softbs (bnc #833765). Beyond that, ARM sparse detection has been sped up a bit (~15%), and the man page has a clarification w.r.t. the meaning of -y. autoconf is now used to detect platform features to help portability.
Release Notes: This release brings some further optimization of the SSE2 sparse block detection (adding 40% performance). There's also code for AVX2, but it's disabled, as it couldn't be tested. There's a test case for the 1.35/1.36 bug now that can be run by make check. ETA and curr.rate have been improved a bit (floating averages), and the --force/-f switch gained the capability to override a non-zero output position for non-seekable ouput files.
