Looking at the changelog it looks pretty significant for the new user. Will make it easier.
"- all strcpy and strcat's in ldp-vldp.cpp replaced with safer versions that cannot buffer overflow"
makes daphne more stable.
"- command-line argument size has been increased to 320 characters from 80.
This allows people to run daphne from within many nested directories, or from within directories with long names"
Self explainitory on why this is good.
"- a "-nojoystick" option has been added to prevent daphne from using a joystick if desired"
A plus for some users.
"- parallel port support for win2k/winxp is now built-in (an external program such as directio or allowio is no longer needed)"
Probably the coolest addition
