Release Name: Solar Eclipse 8.0.0 Linux beta version

**** New in version 8.0.0

1. Version 8.0.0 is compiled with 64 bit memory model (linux releases
only) to enable handling larger numbers of traits, parameters, and/or
individuals per pedigree. However, memory beyond 2 Gb can not usually
be allocated because contiguous memory is currently required. That may
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 than
causing an unexplained crash as usually happened before.
Maximization is about 2% faster for all model types.
