 | WX/NET IS NOW WINDOWS COMPATIBLE! (GUI client only):
Added Windows compatibility for wx/net client. Tested with ActiveState.com's ActivePerl (Tk included). May work with other distributions as well. The
sdadmin script currently does not work correctly under Windows, working to correct.
|
| Changed rainfall rate real-time calculation from static window to an adaptive rate algorithm. The RAINRATEINTEVAL option in wxserver.cfg is deprecated and may be removed.
|
| Integration with The Weather Underground's (www.wunderground.com) personal weather station project added. An upload script template entitled perswxtmpl.pl is included with the distribution. Add the station ID and password assigned by wunderground.com to the wxserver.cfg file (new options WUGSTNID and WUGPASSWD. Then add the supplied perswxtmpl.pl script as an HTMLIFILE, and perswxul.pl as an HTMLOFILE, also in wxserver.cfg. wx/net will read in the template and substitute correct values, writing the new script to perswxul.pl. Finally, add perswxul.pl as a TASK in wxserver.cfg as often as you would like data uploaded. Note: the script uses the LWP package from CPAN. You are free to write any other script to do the same data upload, using the HTML/ASCII substitution feature of wx/net.
|
| Enhancements to HTML keyword substitution. All times may be requested in local standard (lst), local daylight (ldt) or Universal (utc) time units. Hours may be specified in either 12 hour or 24 hour formats. All dates may be requested with long or short year format. Additionally, hour, minute, month, mday, and year fields may all be requested individually for any given time/date value. These enhancements were implemented as part of the wunderground.com personal wx station integration. See user manual for more details.
|
| Added seconds support for latitude and longitude parameters. This caused the IPC protocol between the server and client to upversion, so both components must be upgraded or else latitude and longitude data will be broken. Also, the wxserver.cfg file must contain a field for seconds now.
|
| Refined barometric units conversion formulae to be more accurate.
|
| Added new wind chill formula adopted by NWS in 11/2001. This is selectable
with the new WINDCFORMULA option in wxserver.cfg. The old wind chill formula
is still supported if desired.
|
| Fixed significant rounding errors in windchill, heat index, and dewpoint
formulas internally. Implemented different dewpoint formula altogether.
|
| Added centimeters to the family of units for all rainfall and rainfall rate
fields.
|
| Added hectopasacls (hPa) to the family of units for barometer and barometric
rate of change measurements. This is identical to millibars (mb), which
is still supported.
|
| Opened up IPC fragmentation window from 8K to 64K. This greatly improves
speed on large data transfers such as GIF images in the product catalog.
The fragmentation is dictated on the sending side, so new versions will
still be able to talk to older versions using the smaller window. Also, the
receiver will attempt to read in more than 8K at a time, also improving speed
but preserving compatibility.
|
| Shortened minimum animation interval from 100ms to 50ms. This allows the
broadcast scrolling animation to be twice as smooth as before. Combined
with the faster data transmissions, broadcasts should be much more smoothly
animated.
|
| Added enhancement to detect WMAX-only configuration faster if WLOG is set to
Y in wxserver.cfg but no WLOG is attached.
|
| Server HTML documentation updated.
|
| Fixed bug with improper calculation of timezone on December 31 of each year.
