v2.0.1

Bug fixes in the "DIRECT_FIT.f90" subroutine.

v2.0.0

First release of CHIPR-4.0. This version is a major extension of the previous CHIPR-3.0 code which, besides diatomics and triatomics, also includes the possibility of fitting global PESs of A₄-, AB₃-, A₂B₂-, ABC₂- and ABCD-type tetratomic molecules. Additionally, a new feature is that it allows the user to fine-tune ab initio diatomic curves using available spectroscopic data.

v1.0.0

First release of the code dealing with only diatomic and triatomic molecules.
