2.1.0

This release adds support for misassembly correction and scaffolding
using linked reads, using Tigmint and ARCS. (Tigmint and
ARCS must be installed separately.) In addition, simultaneous optimization
of s (seed length) and n (min supporting read pairs / Chromium barcodes)
is now supported during scaffolding.

abyss-longseqdist:

• Fix hang on input SAM containing no alignments with MAPQ > 0

abyss-pe:

• New lr parameter. Provide linked reads (i.e. 10x Genomics
  Chromium reads) via this parameter to perform misassembly
  correction and scaffolding using Chromium barcode information.
  Requires Tigmint and ARCS tools to be installed in addition
  to ABySS.
• Fix bug where j (threads) was not being correctly passed to
  to bgzip/pigz
• Fix bug where zsh time/memory profiling was not being used,
  even when zsh was available

abyss-scaffold:

• Simultaneous optimization of n and s using line search
  or grid search [default]

SimpleGraph:

• add options -s and -n to filter paired-end paths by
  seed length and edge weight, respectively
