v1.4.1

• Bugfix: Wrong panel positioning when select is at bottom edge of viewport
  due to overridden panel height (350px). The default panel height (256px) will be used
  #63

  Note: the panel height can be changed via css (not recommended, as it leads to issues):

  .mat-select-search-panel {
    ...
    max-height: 350px;
  }

  Thanks to @hadsy for reporting.
