Version 1.1.1

Changed in this version:

• Set memory limits on markduplicates step, which fixes a memory error for WGS runs of >1.5B reads per sample
• Remove build numbers from conda environment files, as those get retired.
• Fixes conda environment files containing matplotlib
• Per-exon coverage metrics will have slightly lower mean_gq values, as vtools now calculates mean gq over the raw P-values.
