  • Improved the behavior when exporting aligned sequences from Align to Reference Sequence mode.
    (Reported by Lauri Lintott)
  • Made the reference sequence bold when printing an alignment to a reference sequence.
  • Improved Enzymes view so that selecting an enzyme in the name column no longer changes the sequence selection.
  • Improved stability when printing maps with long stretches of N's on macOS.
    (Reported by Ben Low)
  • Enbled import of primers from Clone Manager files that contain vertical tab characters.
    (Reported by André Michaelis)
  • Improved consistency when importing protein sequences from NCBI.
  • Fixed a number of issues with choosing and preserving templates while using cloning, gel, primer, and mutagenesis dialogs.
    (Reported by Yan Lu)
  • Improve scrolling to selected files in collection windows.
  • Updated the Addgene importer to recognize the new database output.
  • Improved multiple sequence alignment consensus accuracy.
  • Improved the import of primer lists copied from Excel.
    (Reported by Greg Shackleford)
  • Ensured that the selection in Sequence view's minimap is always blue when the window is active.
  • Fixed various issues when saving documents to non-native file formats (GenBank, FASTA, etc.).
