Moved comment thread registration to componentDidUpdate to avoid adding deleted comments
Added CommentThreadStore.deleteComment to register deletion of a comment
New comment ids are now tracked so we can determine if a deleted comment counted towards newCommentCount
Renamed getCommentStats() to getCommentData()
CommentThreadStore.init() now returns the result of getCommentData()
Renamed prevMaxCommentId -> maxCommentId in Item, ListItem and CommentThreadStore output
Display the number of new threads in a ListItem
Fixed a bad export
