  • Bug fixes:
    • weight2rows:
      • no longer reorders the columns in the result

hutils 1.1.1 Unreleased

  • Change of stable test:
    • The only changes were so that the test proceeds when a required package is present. The tests would never have succeeded in cases where they now skip. Consequently the major version number has not been incremented.

hutils 0.9.0 2017-10-22
