Version Published Release Notes

Reinforce deprecation by shortening the description, removing
the tags, and replacing the image.

Synchronize with GeographicLib 1.43.
Fix bug in the long_unroll feature of geodreckon.

Deprecation notice. Use the GeographicLib toolbox instead.

Update to GeographicLib 1.41.1. Point fix for geodarea.m to handle
polygons which encircle the pole multiple times. E.g.,
geodarea(89+zeros(6,1), [-360:120:240]')
used to return -2.5500e+14 (incorrect);
it now returns 3.2415e+10 (correct).

Offer as toolbox.

Uncheck toolbox

Synchronize with GeographicLib 1.39. Fix the bug in geodreckon
noted on 2014-10-29. Provide the option to prevent the longitude
returned in geodreckon from being reduced to [-180,180).

Synchronize with GeographicLib 1.38.
Minor documentation changes only.

Minor improvements to the calculation of short geodesics and the computation of areas.

Update journal reference.

Update to GeographicLib 1.28. Fixes 2 bugs: (1) incorrect area returned in certain obscure cases; (2) m12 incorrect for meridional geodesics.
