then you can remove Time/event.[ch]xx and Include/fg_callback.hxx from
the repository.

non-existant aircraft or have an error in a custom XML file, they'll
get an error report, at least.
system. A chap from Germany called Alexander Kappes (cc'd) got
in touch with me a few weeks ago and has written the start of
Approach control. At the moment tuning in to a valid approach
frequency (Dortmund or East Midlands) should result in vectors to
a spot about 3 miles from the active runway, and a telling off if you
stray too far from the correct course, in the console window. He
seems to know what he's doing so expect this to improve rapidly!!
I've added a rudimentry AI manager and a hardwired Cessna at
KEMT on the runway - I'll remove it before the next release if I don't
have it flying by then. There seems to be an issue with framerate
which drops alarmingly when looking at it - I've a feeling that I've
possibly created several Cessnas on top of each other, but am not
sure.
- implement the standard FGSubsystem interface, for consistency
- eliminate current_autopilot and add get/set_autopilot to FGGlobals,
for consistency
- use private methods rather than static functions for tying

There should be no change in functionality.
is a work in progress and needs severe enhancement before it will be
useful. It provides a UDP data channel that goes both ways between
flightgear and the fdm. It also provides a TCP 'command' channel so
flightgear can 'reliably' send commands to the remote fdm (such as set
starting position, reset on ground, etc.)
subsystem to Flightgear. No more functionality is implemented
than at present (apart from an ATIS bug-fix - station wouldn't
change if the radio was switched directly from one station to
another) but it is much neater than the current hack and should be
easily extendable.
Some cruft is still probably left over in radiostack.[ch]xx such as
the bindings to the comm frequencies but I'll leave removing those
until I'm sure they're not needed there.
Added two new properties:
/environment/temperature-sea-level-degc
/environment/pressure-sea-level-inhg
These are now supported in FGEnvironment as well, though they always
have the same value for now. They need to be hooked up to the FDMs.
different locations, and hitched it into FGGlobals. FGEnvironmentMgr
has taken over as the subsystem, while FGEnvironment is simple the
information that it returns. I've removed current_environment
completely -- everything now uses properties or goes through
FGGlobals. FGGlobals itself has a couple of useful methods:
const FGEnvironment * get_environment ();
const FGEnvironment * get_environment (double lat, double lon, double alt);
The first one returns the environment data for the plane's current
position, while the second returns the environment data for any
arbitrary location. Currently, they both return the same information,
but that will change soon.
properties have been renamed from wind-(north|east|down)-fps to
wind-from-(north|east|down)-fps, and the FDMs modified appropriately.
No other changes should be visible unless FG_OLD_WEATHER is defined.

Akso found and fixed a bug in the simgear that caused the time to go goofy
temporarily while scenery was being loaded.
/sim/freeze/master (implimented)
/sim/freeze/fuel (implimented)
/sim/freeze/position (not implimented)
/sim/freeze/time-of-day (not implimented)
/sim/freeze/master is bound to the 'p' key via keyboard.xml, however,
/sim/freeze/fuel is not bound to anything at the moment so you must
change it via the external property interface, or specify an initial
value on the command line.
function to allow property files as non-option parameters after the
options have finished (and added "--" to terminate options). It's now
possible to do something like
fgfs denver-am.fgd
or even
fgfs at-lax.fgd in-c310.fgd around-sunset.fgd
This works the same way as the --config option, but will be friendlier
for GUIs, where start-up situation files can now be associated easily
with FlightGear.
material-specific logic is now removed from the material library and
encapsulated in the material class itself, and materials are loaded
from $FG_ROOT/materials.xml rather than $FG_ROOT/materials. This also
removes a nasty bug in the old material-loading code that caused a
floating-point exception.
works like this:
1. Parse preferences.xml, which will usually specify a default
aircraft using the /sim/aircraft property.
2. If /sim/aircraft is specified and not empty, parse the properties
in $FG_ROOT/Aircraft/{/sim/aircraft}-set.xml to set up a default
aircraft.
3. During command-line parsing, whenever the --aircraft option appears
set /sim/aircraft appropriately and parse the properties in
$FG_ROOT/Aircraft/{/sim/aircraft}-set.xml. Any --config, --prop, or
--aircraft options afterwards will take precedence.
more intuitive. We switch to an include in the preferences.xml to include
the default model, and then if the user specifies --aircraft=, that is
expanded immediately so portions can be overwritten by subsequent command
line options.
a top level aircraft def file (c172-set.xml)
preferences.xml or --aircraft= or any other property setting mechanism can
be used to set the property "/sim/aircraft". After all options and config
files are parsed, the contents of /sim/aircraft is expanded into a *-set.xml
file and loaded.
fix startup sequence problems where we initialize the FDM before we know
the desired starting altitude.
These changes delay fdm initialization until the local tile has been loaded
and we can do a real intersection and find the true ground elevation.
In order to do this, I depend more on the property manager as glue, rather
than the FGInterface.
There are some glitches still when switching to a new airport or reseting
the sim. I will work on addressing these, but I need to commit the changes
so far to keep in sync with other developers.
meaning of "win_ratio". I've removed win_ratio and added fov_ratio and
aspect_ratio, as it seems both are needed.
n.b. The multi-line changes in fgReshape comprise:
extracting common code,
removing an apparently arbitrary "+1" on the view height,
changing "set_win_ratio" to "set_aspect_ratio".
I've updated the WeatherDatabase to be able to use only the n closest
stations. This can speed up the initalization dramatically.
To take a benefit from that you need:
- http://129.13.102.67/out/flight/current.txt.gz in
FG_ROOT/weather/current.txt.gz
- --prop:/environment/weather/working-type=internet
- --prop:/environment/weather/max-stations=what_ever_you_want
The WeatherCM stuff now publishes its data in the property system.
/environment/weather/wind-north-mps
/environment/weather/wind-east-mps
/environment/weather/wind-up-mps
/environment/weather/temperature-K
/environment/weather/air-pressure-Pa
/environment/weather/vapor-pressure-Pa
/environment/weather/air-density
are the new properties.
