* extended backwards compatibility mode to allow already fixed bug with
  change actions (see "2008-02-05") for existing levels (especially the
  Zelda and Zelda II levels and other cool stuff by Alan Bond like FMV)
* reactivated workaround to prevent program crashes due to blitting to
  the same SDL surface that apparently only occurs on Windows systems
  (this is no final solution; this problem needs further investigation)
* version number set to 3.2.6.1
* version 3.2.6.0 released
