Version 5.0.2 was released on Apr 23, 2020! This is a point release which fixes several issues reported in version 5.0.1, however there are also some new features.
For more details, please see the Release Notes which are now available from the program Help.
A very long-standing error has been identified in the Invariant Analysis perspective. The value of the specific surface Sv that is being returned is in fact twice the value that it should be. Work is underway to correct this and some other deficiencies in the operation of the perspective, but version 5.0.2 benefits from the significantly enhanced invariant documentation stemming from this work.
Also, at this time, and unlike version 4.x, only fitting sessions can be saved as project files. We expect this to be corrected in the next release.
