Here are the details of that log message:

Changes in version - 2016-12-19
  Tor is the first alpha release in the 0.3.0 development
  series. It...improves the algorithm that
  clients use to choose and maintain their list of guards...

  Below are the changes since

  o Major features (guard selection algorithm):
    - Tor's guard selection algorithm has been redesigned from the
      ground up, to better support unreliable networks and restrictive
      sets of entry nodes, and to better resist guard-capture attacks by
      hostile local networks. Implements proposal 271; closes
      ticket 19877.


This is the description of the "normal" guard context:

  /** Use the normal guard selection algorithm, taking our sample from the
   * complete list of guards in the consensus. */


The message comes from create_initial_guard_context().
