Note some of the significant changes:

  * Python MapScript now only provided for Python 3 (python3-mapscript)
  * PHP MapScript available again (php-mapscript)
  * PHPNG MapScript based on SWIG also available (php-mapscript-ng)
  * Ruby MapScript no longer available (ruby-mapscript)

Kind Regards,
