2016-11-09 : zyGrib Version 8.0.1
Bug fixed: inverted sea current arrows (one more time).
There was a problem with some dll in the Windows archive of the previous
version.
2016-11-08 : zyGrib Version 8.0.0
Read GRIB 2 files.
Bug fixed: inverted sea current arrows.
Display equivalent potential temperature théta-e at the surface and in
altitude (calculated from the temperature, pressure and moisture if it
is not present in the file).
Faster calculation of the level lines.
Ability to interrupt before the opening of a large file.
Use QT version 5.
Use g2clib NOAA's g2clib library for decoding the GRIB2 format.
Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.
Problems found locating distfiles:
Package colorls: missing distfile ls.tar.gz
Package molden: missing distfile molden-4.6/molden4.6.tar.gz
Package softmaker-office-demo: missing distfile ofl06trial.tgz
Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
2015-01-18 : zyGrib Version 7.0.0
Download and display new data GFS from NOAA: grid 0.25°x0.25°
and up to 10 days forecasts.
Restriction: for long-term files, only the first 5 days are
with a grid of 0.25°, beyond the grid is 0.5°.
2014-11-02 : zyGrib Version 6.2.4
Reading grib files at high resolution from model SKIRON (University
of Athens, Department of Physics, Atmospheric Modelling and Weather
Forecasting Group) available here : http://wild-silk.org/en.
2014-01-09 : zyGrib Version 6.2.3

contained the longitude of 180°.
2014-01-04 : zyGrib Version 6.2.2
Bug fixed: the wave model was not always displayed correctly in the

Bug fixed: it was impossible to disable isolines.
2013-11-13 : zyGrib Version 6.2.0
Map scrolling with the mouse (+Ctrl).
Note: this first version is not really optimized. The movements
are jerky if the grib file is too large or if the machine
is too slow.
Reminder: click with the middle button to move the target point to
the center of the window.
Enhancements of the curves module (thank you François-X): the main
window remains active, other curves can be opened.
wind gust display with lines.
temperature display is correct even if the grib does not contain the
min/max temperatures.
deflection curve of the wind no longer interferes with the pressure
and cloudiness.
More accurate display of jet streams with a color scale modified
(adaptation of a proposal from Sailingyachto2 aka ON3CHD). the wind
below 40 kts is ignored and the scale goes up to 240 kts.
Use key combination 'Ctrl+Maj+J' to toggle between jet stream
colormap and the standard one, or navigate in the menu 'Weather
map'->'Options'.
Bug fixed: loss of the altitude displayed at startup or when
loading a new file.
Pseudo bug fixed: a stable version of the qwt library is installed
with source files, because it is not compatible with itself from
one version to another.
2013-04-28 : zyGrib Version 6.1.4
Bug fixed: the levels 400 and 600 hPa are fully taken into account.
2013-04-08 : zyGrib Version 6.1.3
New russian translation (####### Yaroslav Zavarzin).
Export SkewT data in a spreadsheet format.
2 new levels of altitude : 400 hPa and 600 hPa.
Warning : you have to check "SkewT" in the tab "Altitude" to retreive
data, so files are big.

Possibility to choose run GFS (Last, 0h, 6h, 12h, 18h) at download. Warning : it is slow, except for the last run.
The maximum size of the files generated by the server is 100 MB (instead of 50).
The values panel is in a scrollable area.
Bug fixed in the curve drawer module (thanks François-X).
Less bad estimate of the size of the files.

from NOAA GFS archive (analysis data), available since 2004.
* Cover: worldwide, grid of 1°x1°, 4 files per day.

available here: yr.no
Limitations:
displays weather data (wind, pressure, temperature, precipitation)
and waves but not other oceanographic data available in these files
(salinity, currents, etc.).
files curr4km-skagerak.grb et ggeo-Oslofjord00.grb do not contain
data viewable by zygrib.
Some minor bugs fixed (there is still much).
