**** New in version 8.0.0
1. Version 8.0.0 is compiled with 64 bit memory model (linux
only) to enable handling larger numbers of traits, parameters,
individuals per pedigree. However, memory beyond 2 Gb can not
be allocated because contiguous memory is currently required. That
be addressed in future updates. However 64 bit compilation is a
necessary first step, it sometimes helps, and also failed memory
allocation is now usually reported with an error message rather
causing an unexplained crash as usually happened before.
Maximization is about 2% faster for all model types.
