Other than some internal performance fixes, there are two updates in this version:
Quick queue and draft buttons on the “Share” bookmarklet
Prevent the Tumblr dashboard’s endless scroll feature from stalling (and allow you to try again)
#2 is related to this problem with Tumblr’s dashboard endless scroll feature. When it attempts to load the next page of posts, it stops responding if the load takes too long or if the load retrieves a Tumblr error page (tumbeasts) instead of more posts.
