[Christof Schmitt <cschmitt@users.sourceforge.net>]

Hi,

i just released hamfax 0.8.1 to fix some bugs found in the new Qt4 and hamlib
code:

 * Fix checkable entries in options menu
 * Fix hamlib parameters handling
 * Fix hamlib usage: Set PTT for ALSA and do not open hamlib in receive path

Many thanks to Kamal Mostafa for pointing out these issues, and testing the
fixes.
