fstalign-1.3.0
This release includes a new first-pass approximation of the alignment to speedup the real alignment process. The utility will consume more ram than before, but should be much faster in general. The alignment might vary a little from previous alignments.
To disable this pre-processing, once can pass --disable-approx-alignment
on the command line.
