Version 0.9.9 of the Signet client has been released. It features importers for pass password databases and CSV files. The CSV import feature can be used to import data into any data type, making it possible to import from a variety of sources that support CSV export.
You can now categorize accounts into groups for organizational purposes. This allows Signet to preserve KeePass's and Pass's database's tree structures. If you imported from a KeePass database using version 0.9.8.1 you may need to take some additional steps to recover the tree structure of imported accounts. Check the release notes for details.
