4.2.0
^^^^^

Bug Fixes

* Fixes issues with the refresh of "Session" based authentication
  where a previous refresh attempt failing could result in a fallback
  to "Basic" authentication and would silently fail. The client
  library now attempts to re-authenticate.

* Fixes silent failures when a refresh of an authentication
  "Session" fails and was unable to be re-established due to an
  "AccessError". Should this occur, now the "AccessError" exception is
  explicitly raised as opposed to attempting to fall back to "Basic"
  authentication.

* Fixes issues where the "Session" and "Basic" auth interface would
  fallback to "Basic" authentication should a "ConnectionError"
  exception occur while attempting to perform an authentication
  action. "ConnectionError" exceptions are signs of networking
  transport issues, and should be investigated. A "ConnectionError"
  exception is now raised.

* Prevents the combined "Session" and "Basic" authentication support
  from falling back to "Basic" authentication once "Session" based
  authentication has been established. This should be considered a
  potential security issue or an environmental change requiring
  potential client re-initialization. This is exposed as an
  "AccessError" exception. Continued operations against the Sushy
  library will attempt to reauthenticate, if possible.
