Version 4.0 of information organizing application Yojimbo has been released by Bare Bones Software, retiring MobileMe support and bringing in a new syncing mechanism. Yojimbo 4.0 now uses the Wasabi syncing service to move data across devices. Additionally, the application now supports full screen mode for the main window, as well as certain item windows.
Yojimbo's database format has changed due to the changing syncin mechanism, with databases being automatically converted to the new format. Older databases will be backed up before they are converted, however. Additionally, there have been a number of fixes and improvements. Yojimbo 4.0 requires OS X 10.8.2 in order to run. You can download Yojimbo as a free trial, or buy it for $30 from the Bare Bones Software site.
