Release for the journal paper.
The most significant change, is the switch to a new population format, which allows streaming the binary population file. This way, it is possible for each process to only load a subsection of the population, which reduces the memory requirements so that larger scenarios can be run.
Additionally, this release supports paths relative to the configuration file. This feature enables to load input files onto computing nodes before the simulation starts, and to write output files to the local SSD of computing nodes.
