From http://www.garloff.de/kurt/linux/ddrescue/: Latest version is 1.99.4 (2016-08-25) Version 1.99.4 has a couple of fixes on top of 1.99: A memory corruption was resolved when using fmt_int() improperly, which was the case when a list of bad blocks was written out with -b. Thanks to Marc Thomas for reporting and debugging. A segfault with the graph with reverse direction copies was also fixed as well as improved flexibility to compile ddr_crypt plugin with incomplete support for new insns.
not a clean release ... they changed the 1.99 tarball, and the 1.99.4 is a patch on top of the tarball
