Fix all the errors to get our tests green on Rails 5.1. 2017-08-31 00:06:56 -04:00			`class AddUnreadPmIndexToNotifications < ActiveRecord::Migration[4.2]`
FIX: Always ensure notifications are treated as read once clicked UX: improve messaging so notifications list is far more stable PERF: improve performance of notifcation lookup queries - Add feature "SetTransientHeader" that allows shipping info to server in the next Ajax request - remove local storage hack used for notifications - amend lookupStale to return hydrated objects, move logic into store - stop magically clearing various notifications (likes, invitee accepted, group_summary, granted badge) 2016-02-15 03:29:35 -05:00			`def change`
