  +### Changed
  +
  +- New method for auth protocol handler detection. This should fix sign in flows for
  +most major web browsers and operating systems with both the native browser installed and
  +not installed.
  +- NOTE: If you're using this version of blockstack.js with an old version of the native
  +browser, the app will (1) open an auth handler in the native browser and (2) also redirect
  +the original tab to browser.blockstack.org.
