Version 0.3.0 of the General Astrodynamics Library has 
been released. It can be downloaded from the project 
website here:


Updates in this release:

         * ODE Integrator sub-library created.

           Lunar position and velocity routine added to 
           sub-library. Routine implements LUNAR SOLUTION 
ELP version ELP/MPP02

           Solar position and velocity routine added to 

           Acceleration from spherical harmonics routine 
added to
           gravity sub-library.

           Many routines updated for internal compatibilty 
with the upcoming
           official IAU SOFA C library. R-matrices have 
had indicies
           reversed compared to GAL 0.2 and earlier.

Work will now be started on the classical keplerian 
models, and atmosphere models.

The General Astrodynamics Library (GAL) is a numerical 
library for C and C++ programmers. It is free software 
under the GNU General Public License.

The library provides a wide range of astrodynamical 
routines such as ephemerides, earth orientation, and orbit 
propagation. There are over 225 functions in total with an 
extensive test suite.
