Version 0.75 - 24.05.06

• All system calls were removed to improve robustness under certain MPI implementations.
• Possible size of FFT-grid (and non-weird number of processors) has been extended to full range of FFTW3. One possible divisor of either 11 or 13 has been added.
• Robustness of makefiles with Intel compilers 8.1 and 9.0 in conjunction with MPICH has been increased.
• Sample script for Sun Grid Engine has been added: sample/test.sge.
• Different descriptions of Gaussian beam are now fully operational.
• Origin is now always in the center of the computational box (before it was not so when jagged>1).
• When incident field was used as an initial vector of the iterative solver, more iterations than necessary to reach epsilon were performed. Fixed.
• Progress reported in the first iteration after checkpoint loading was incorrect in certain cases. To fix it required loss of checkpoint compatibility with earlier versions. More information is now displayed after checkpoint loading.
• Robustness of generation of error messages in parallel mode has been increased.
• Calculation of C_sca or g caused both polarizations to be calculated even for particles that are symmetric for 90 degree rotation over the z-axis. That is not necessary - fixed.
• Integration module has been significantly improved. It automatically uses the trapezoid rule for periodic function. Error estimates now seem to be reliable. Format of parameters for integration module has been changed because of the improvement.
• Homepage of ADDA has been created.

Version 0.74.2 - 05.04.06

• Makefiles has been improved to allow simple usage of Intel compilers.
• A section describing FFTW3 installation has been added to the manual.

Version 0.74 - 29.03.06

• buggy beam type has been removed (obsolete).
• Command line options -nosym and -sym_enf has been combined into '-sym {no|enf}'.
• Internal fields are now automatically collected into one file, when running in parallel mode (named IntField-X and IntField-Y)
• MPI-specific command line options has been enabled.
• Geometry filename given to the command line option -save_geom should now be specified relative to the output directory.
• In parallel mode each processor (except root) produces a separate logfile, if any errors or warnings were detected (on this specific processor).
• Overall robustness of the code is improved (added many consistency checks).
• Help system has been added (new command line option -h).

Version 0.73 - 02.03.06

• First stable release that has a manual and other documentation
