    (Reported by Michael Nielsen)
  • Fixed an issue with updating the position of feature cleavage arrows when performing a large insertion or replacement upstream.
    (Reported by Tore Dehli)
  • Ensured robust primer design in various contexts where compatible overhangs must be created.
    (Reported by Wei Guo)
  • Enhanced the import of oligos from Vector NTI database and oligo archives.
    (Requested by Dominique Aubert Skovlund)
  • Improved the consistency of importing full sequences from Addgene.
    (Reported by ChangHee Lee)
  • Fixed an issue where copying and pasting portions of aligned sequences could transfer invalid feature data.
    (Reported by Lianna)
  • Ensured a robust response when opening or pasting FASTA-encoded protein sequences.
    (Reported by Steven Erickson)
  • Tweaked the wording when using Cut, Delete Amino Acids, or Insert Amino Acids in SnapGene Viewer, where the resulting dialog referred to bases instead of amino acids.
  • Improved the painting of full sequence colored ranges or N-stretches in circular maps.
  • Ensured the translation of "None selected" to Japanese in various contexts.
  • Fixed an issue where if you cleared the sequence in the New, Insert, and Replace Bases/Amino Acids dialogs, the length was not reported correctly.
  • Ensured the correct font size for error message in import dialogs on Windows.
  • Ensured proper resetting of controls in the “Choose Alternative Codons” dialog after resetting the codon usage table to "None".
  • Fixed an issue where specifying "Met" in insertions controls in the Add/Edit/Duplicate Primer dialogs would result in "ATG" being listed twice in the list of codons that can be inserted.
  • Corrected the message that appears after clicking the disabled toggle 3-letter codes button when no sequence is loaded.
  • Ensured that the subsidiary controls in the Reverse Translate dialog are disabled when appropriate.

  • Ensured that the name for files opened from web links do not use “%” encoded symbols.
  • Ensured that the "Detect Common Features" checkbox is always visible when using the "New DNA File" and "Insert/Replace Bases" dialogs.
  • Improved stability when Paste or other keyboard shortcuts were quickly tapped multiple times before the Insert/Replace Bases dialog could be shown.
  • Provided consistent use of bold font for disclosable labels in the Letter Codes dialog.
  • Prevented the display of irrelevant messages when clicking disabled buttons in the side toolbar of an empty manipulation dialog.
  • Improved the rendering of pliancy for enzymes, features, and primer names in circular and linear maps.
  • Added missing HTC and ENV (high-throughput cDNA and environmental sampling) Natural DNA sequence class options.
  • Fixed an issue that resulted in the right side of tooltips being clipped slightly.
  • Enhanced anonymous statistics to identify macOS 10.12 as "Sierra”.
  • Prevented the use of invalid characters in filenames on Linux.
  • Improved the disk image background on macOS 10.11 and later.

  • Improved the formatting of negative floating point numbers.
  • Prevented a potential issue with invalid network time stamps.
  • Improved the translation numbering of multi-segment reverse directional features when using the Make Protein command.
  • Closed a loophole that allowed feature translation options to be edited in read-only contexts (manipulation dialogs) by using the Sequence view minimap.
  • Ensured that "Reverse Translate" using degenerate codons works for amino acids with only one codon (e.g., M = ATG).
  • Fixed an issue where TA cloning could fail when using a non-TOPO vector and phosphate groups on either the vector or insert.
  • Corrected a rare glitch where feature names in linear maps could sometimes be drawn on top of each other.
  • Improved stability when closing documents.
  • Improved stability when opening recent documents from the launch dialog.
