Release Notes: Support for SATA SSD TRIM commands was enhanced with the introduction of several arguments. In addition, an experimental script ( is provided which calculates a list of unallocated blocks within a filesystem, and informs the SSD firmware of those blocks. In some cases, this can restore a sluggish SSD to nearly-new speeds again. Furthermore, a workaround to an observed ext4 bug with FIEMAP's "LAST" flag was added, and the "-E" flag was modified to work with modern DVD drives.

New flags "--make-bad-sector", "--repair-sector", and "--read-sector" were added. The "-N" flag was added to get/set max address/HPA. Many other fixes and enhancements were made.
