This is a fairly small release with some important fixes in it:
d8896f24 Fix lazy currentUser (#5862) -- Josh Kuhn
c8981763 Making storeLocally default to true (#579) -- Mardo Del Cid
horizon.currentUser was previously lazy, requiring you to horizon.connect() or do some other query to get results from it. Now when you subscribe to horizon.currentUser().fetch().watch() you'll get what you expect immediately.
v1.1.1 introduced a bug where tokens were no longer stored in localStorage, thanks to @mardo this is now fixed.
If you experience any issues, please let us know on the v1.1.x Known Issues Discourse Topic
