Everything is new. We've re-designed scheduling from the ground up, including more reliable communication, better time zone support, export to Outlook and iCal, backups/alternates, and a new fast mode where ethnio chooses participants for you and invites them to participate automatically. If you use the scheduling feature in ethnio, or have thought about using it, here's the list of everything we've just changed to make it way easier to use and more reliable.
New Responsive Design
This is the new calendar design that shows you open interview spots and potential participants in a much friendlier way. You can bulk add spots with that green plus, and toggle weekends at the top right. The whole page is responsive now, and generally faster.
