This release includes some great enhancements:
- Improved issue display
- Issue previews
- Dashboard for notifications and issues assigned to you
- Improved label management
- Assignee management
- More supported GitHub URL styles
- Request mocking (should make PRs much easier!)
- Emailing users
- Smarter headers
- Greatly improved/stabilized cache handling

We're now offline-by-default, sorta.  Normally, we will retrieve
GitHub data if it has not been retrieved before.  Successive requests
will always use the cache. Refresh a buffer's GitHub data by giving a
prefix argument to `M-x magit-refresh' (usually bound to `g', so use
`C-u g').  Some sections rebind `g' (like repo status) for
convenience.

Hop in and explore!
