You can now directly circularize a selected restriction fragment. When attempting to circularize a PCR product with single 3′ base overhangs, SnapGene now offers to remove those overhangs in order to make circularization possible. Finally, history colors are now generated when circularizing. You can now export Map and History views at various resolutions. Improved support exporting transparent images. When exporting as TIFF, SnapGene now uses LZW compression and transparent TIFF’s are now also supported. When copying a map or history to the clipboard a vector form of the data is now stored on the clipboard so elements can be moved or edited when pasting into programs like Microsoft Office or Adobe Illustrator. Added the full template name to the tooltip shown when mousing over the list in the Simulate Agarose Gel dialog if the name is truncated within the list. When exporting History view to PDF, we now use Portrait instead of Landscape orientation since it usually fits better that way. Improved exporting to GenBank to better conform to the standard and resolve various warnings when converting to EMBL when uploading files to EMBL-EBI. Fixed bugs with visualizing insertions at the numerical origin and replacing the original with the aligned sequence under such circumstances. Fixed a bug where if no attB inserts are to be amplified by PCR, when clicking ‘Choose attB Primers’ SnapGene should pop up a message instead of doing nothing. Improved exporting to SVG. (The bounds of the exported content are not set so scrolling, if necessary, is much improved). Fixed a bug where the default filename when using Save As was sometimes incorrectly set to ‘Untitled’ on Mac OS X 10.9 and later. Fixed a bug where when simulating a manipulation using an open document with unsaved case changes, those changes were not reflected in a resurrected ancestor. Fixed a hang when deleting bases from a single strand from an end that is currently covalently closed while using the Edit DNA Ends dialog. Fixed a bug where when enlarging the Edit DNA Ends dialog, additional space not used entirely for viewing the upstream and downstream ends. Fixed a bug where if a mixture of colored and non-colored features were selected when triggering ‘Features → Feature Color’ no option should be checked by default. Fixed a bug where an error message was shown twice when trying to open a GenBank file that does not contain a nucleotide sequence. Fixed a crash that could occur when importing a GenBank archive that contains on or more empty sequences (aka sequences without nucleotide data). Fixed a bug where if enzymes were off and you opened and then canceled out of the Choose Enzymes dialog SnapGene would offer to turn on showing enzymes. Source.
