AgileBits has released, enabling 1Password Watchtower by default and clarifying the sync options shown during initial setup. The update also fixes a layout issue where the Trash would float halfway up the sidebar, resolves a bug that prevented the Watchtower database from updating automatically, and eliminates a crash when adding a 1Password.com account by signing in using a Web browser. AgileBits also ensures that those who purchased 1Password via the Volume Purchase Program on the Mac App Store won’t be put into read-only mode.
As of version 6.6, the edition of 1Password is now free to download and works for 30 days in trial mode. After that, it prompts you to subscribe to 1Password — see this AgileBits  for details. ($64.99 new  or free with a $2.99 or $4.99 per month subscription, free update, 47.4 MB, , 10.10+)
