Hosts: Replace the PHost program. If you want this version behave like the previous one as close as possible, add the following values to pconfig.src. We recommend you to use the defaults, though, to try our new rules.

% PHOST
AlternativeMinesDestroyMines = Yes        # default: No
TowedShipsCooperate          = No         # default: Yes
WrmScanRange                 = 0          # default: 100
EPTrainingScale              = 100        # default: 70
CPEnableEnemies              = No         # default: Yes
CPEnableShow                 = No         # default: Yes
CPEnableRefit                = No         # default: Yes

% PCONTROL
MinesDestroyMines = Skip

Remove the RobotsBuildFighters, RebelsBuildFighters and ColoniesBuildFighters parameters from pconfig.src, and add a matching AllowBuildFighters setting (usual default: No,No,No,No,No,No,No,No,Yes,Yes,Yes).

If you have used the default complete.src or tim-host.src, please check the settings for FighterSweepRate and FighterSweepRange. The files shipped with versions up to 4.0b were bogus. The settings should read FighterSweepRate = 0,0,0,0,0,0,0,0,0,0,20 instead of just 20 - the latter allows fighter-sweep for all players! The same goes for FighterSweepRange.

If you have mentioned the WormholeScan phase in your config file, be aware that this phase was moved.

In case you have re-assigned hull functions, be aware of the changes introduced in 4.0i. For example, ImperialAssault ships do no longer have automatic PlanetImmunity.

The plang4en.hst file is no longer used, you can remove it.

Players: Update the PVCR program. The current version 4.0k(2) plays combat generated by all current PHost versions and all possible configurations.
