- Improved responsiveness when performing or opening a file with an alignment to a reference sequence

- Fixed an issue with renaming folders in collections
- Avoid switching from Map to Sequence view after importing sequences to align to the reference
- Fixed an regression where features in replaced regions were erronously retained during restriction cloning if the insert was the same size
- Fixed an issue with decoding features from GenBank files generated by CHOPCHOP
- Fixed aligning sequences in a multi-sequence FASTA file with a reference
- Fixed an issue with opening supported file types in Miscellaneous Files when viewing a collection
- Fixed a default file name and extension when saving a sequence trace
- Addressed an issue where Sharepoint index conflict files resulted in new file notifications when working with collections
- Improved stability when detecting common features
- Fixed an issue where the selection bar was blank after making a feature in a multiple sequence alignment
- Fixed a crash when attempting to create a custom feature type in SnapGene Viewer
- Fixed an issue that prevented loading non-installed custom feature types that are embedded within a file
- Improved stability with multiple sequence alignments
- Fixed a memory leak when creating, editing, or duplicating features

- Fixed an issue with making RNA sequences from selections in large genomic sequences
- Fixed an issue where unnecessary menus were sometimes shown on the launch dialog
- Fixed various issues where characters right of a period in a agarose gel sequence name was not shown in the fragment list or source control
