- Background map selector. Use either stock maps or own maps of any size.
- Adjust position of satellite names on the map in order to avoid clipping

- Fixed a bug with missing arrows on win32 (bug #1580012).
Changes in version 0.7.0 (3 Jan 2007):
- Automatic update of TLE elements from network or local files. Gpredict can
either notify the user when TLEs are getting too old, or perform automatic
update in the background. The network update requires libcurl.
- Added optional grid lines to the map view (30 deg resolution).
- Added possibility to show ground tracks on the map (feature request #557586)
- Added support for the optional operational status of satellites encoded into
the satellite names in TLE coming from CelesTrak.
- Fixed wrong epoch day in the satellite info dialogue (bug #1586341).
- Polar and Az/El plots of passes in the single-pass dialogue.
Changes in version 0.6.1 (5 Sep 2006):
- Fixed bug that caused data to be installed into the wrong directory when using
'make install DESTDIR=/foo' (patch #1552216 by Denis Leroy).
- Fixed bug that caused errors when user deleted the sample ground station while
one or more modules were still using it (reported by Hamish Moffatt).
Changes in version 0.6.0 (4 Sep 2006):
- New module design: A module is no longer either a list or a map. A module can
contain up to three views that can be any combination of map, list, polar and
single satellite view.
- Each module can be configured individually (colours, views, location) or it
can use the global default settings.
- Module have three states: Docked, Window and fullscreen.
- Improved map view quality and performance with possibility to highlight areas
covered by satellites.
- List View is fully configurable with respect to which columns should be
visible. Furthermore, the list view has a lots of new columns.
- The upcoming passes dialogs can show much more details like TCA, duration and
maximum elevation.
- Context sensitive pop-up menus instead of buttons to access the most important
functions.
- Geographical coordinates can be shown using N, S, E and W suffixes instead
og sign. This should settle the debate on whether negative longitude is East
or West of Greenwich (I know which one is the correct one ;-).
- Added support for imperial units (default is still the metric system).
- Added support for user specified time format strings.
- No upper limit on the number of satellites.
- Uses SGP4/SDP4 algorithms for element set propagation.
- Requires Gtk+ 2.8 or later and GNOME dependencies are gone for good!
- Gpredict is now much more robust against configuration errors. If something
goes wrong you can simply delete all user configuration files and start from
fresh. Besides that, gpredict only uses human readable configuration files,
which can be edited using a text editor. It should, however, never be necessary
to alter the configuration files manually.
- Draft User Manual and Design Document.
Changes in version 0.5.3 (19 Jan 2006):
- Fixed errors when compiling on NetBSD, thanks to Berndt VK5ABN. This patch
actually fixes the i18n installation problems on the other platforms too.
Changes in version 0.5.2 (22 Dec 2005):
- Fixed errors when compiling without hamlib support.
Changes in version 0.5.1 (25 May 2005):
- Selecting local time instead of UTC will now show the correct time
everywhere in the program, thanks to Thierry F4DWV.
- Show pass duration in minutes in the "Upcoming Passes" dialog.
Changes in version 0.5.0 (29 Jan 2005):
- It is now possible to specify a minimum elevation for upcoming passes.
Passes with max elevation below this limit will be discaded from the list.
- Hamlib 1.2.0 support. If compiled with hamlib support, gpredict now
requires version 1.2.0 or later and will not compile with earlier
versions.
- Possibility for other map sizes. Gpredict will automatically detect
the size of the map and scale the canvas accordingly.
- Improved map display showing QTH, time, upcoming satellite and brief info
about a selected satellite. Added buttons for pass prediction for selected
satellite.
- Satellite lists can be sorted automatically at regular intervals
(preferences->lists->autosort). Disabled by default.
- Satmap-druid will now open a warning dialog if the number of
selected satellites is greater than 10 (bug #555595).
- Fixed positioning and alignment errors in AOS prints. Added orbit
number to detailed prints.
- We now use the standard Gnome data directories (incompatible with
previous releases). This means, that the 'configure --prefix=...'
and other directory switches should work now.
- Replaced obsolete ftime function with gettimeofday. The program should
now compile on MacOS X and FreeBSD as well.
- Simple and detailed pass predictions can again be saved to text files
(bug #839373).
- Show rise/set times in Sun and Moon frames.
Changes in version 0.4.0 (17 Apr 2003):
- TLE files are now stored in user's home directory in
$HOME/.gpredict/tle and can be updated automatically at run time.
The supplied files are identicale to those at celestrak.com except
that the extensions have been changed from .txt to .tle
- The tracked satellites are organized in a tree when presented to
the user, rather than a flat list.
- Updated locations database with more than 2000 known locations
with altitude and weather station info. The known locations
are now organized in a tree structure. If Hamlib 1.1.3 is available
locator squares are calculated as well.
- Possibility to have many locations configured and switch between
them at runtime.
- Possibility to use other maps. Gnome Predict comes bundled with 5
different maps, but the user can add and use his/her own maps by
copying the images into the $HOME/.gpredict/maps/ directory. The maps
will automatically be scaled to 800x400 pixels.
- Notebook tabs/labels are only shown if there are at least
two modules in the notebook (the user can override it though).
- Module names can be up to 50 characters long.
- Modules can be deleted and edited after creation (right-click in the
iconbar).
- Program is safe if a satellite somehow disappears from the database.
- Fixed bugs #636186 and #633886.
