DEVONtechnologies updated all three editions of (Personal, Pro, and Pro Office) and  to version 2.9.9, adding an option for importing notes and attachments from Apple Notes to the three editions of DEVONthink. When importing data from Apple Notes (which requires OS X 10.11 El Capitan or later), DEVONthink honors the folder structure and preserves the formatting of notes.
The three editions of DEVONthink also get an improved, more responsive experience when editing text in fullscreen mode (eliminating flickers and supporting substitutions), fix a number of PDF-related issues in macOS 10.12 Sierra, enable encrypted PDFs to be unlocked again, add encoding support for messages dragged from Apple Mail, use MultiMarkdown 5 to render Markdown documents, improve handling of many concurrent synchronizations, and fix multiple issues related to scanning. DEVONthink Pro Office improves archiving UNIX mailboxes and speeds up loading messages from Apple Mail, while DEVONnote receives a workaround that makes random crashes caused by macOS Sierra 10.12.2 less likely.
Shortly after this release, DEVONthink was updated to version 2.9.10 to correct a bug that caused synchronizing with Dropbox to fail. DEVONnote required no updating, so it remains at version 2.9.9.
