Attachments are limited to 5MB.
Favorites are moved to the top of the 1Password menu (above "Show X more items").
This is really, really a disappointing change, one that I hope the users will appeal to change. One of the things I use 1PW for other than passwords is secure document retrieval from my mobile device (instead of using dropbox which is grossly insecure and spideroak which costs a monthly fee). Is there a specific reason why the change was made? Isn't it better to give the user a choice?
