This is a maintenance release of the 7.3.0 version, which is already in use at the University of Zurich. As it includes very important bug fixes, the makers decided to skip the 7.3.0 public version and release 7.3.1 as the current stable release. Most of the bug fixes concern ePortfolio.

Further improvements have tackled the following problems:

• wrong assessment of correct answers of single-choice questions
• display of one question per page and incorrect feedback
• QTI Problem: single-choice questions without a correct answer results in no points (various manifestations)
• QTI Problem: multiple-choice questions without a correct answer cannot be saved, so comments are lost.
