Get it here.
This is the first release built on the new El Capitan operating system. It fixes an issue with video entries on El Capitan along with one about creating an entry from a web site on any OS. Please let me know of any problems you see (especially on El Capitan) using the Report a Bug menu item in the Help menu. Thanks!
(Updated to point to 6.1.7b7, which fixes a crash on launch on OS X 10.10)
