                  by M. Silkowski and K. Pachucki, (2022) - to be published
               -- new 4-body nonrelativistic (DNA) energy added for many levels; currently DNA energy is available for:
                  H2 (v=0,J=0-31), (v=1,J=0-30), (v=2,J=0-28), (v=3,J=5)
                  HD (v=0,J=0-16), (v=1,J=0-12), (v=2,J=0-9), (v=3,J=0)
                  D2 (v=0,J=0-16), (v=1,J=0-12), (v=2,J=0-9), (v=3,J=0)
                  HT (v=0,J=0-5), (v=1,J=0-5), (v=2,J=0-5)
                  DT (v=0,J=0-5), (v=1,J=0-5), (v=2,J=0-5)

h2spectre_7.3  -- hyperfine splitting parameters in Ramsey notation for HT

h2spectre_7.2  -- hyperfine splitting parameters in Ramsey notation for HD (--HF/--hf option added)

h2spectre_dev  -- cosmetic change to the E(7) fit
               -- several grammatic corrections in comments
               -- corrected an error in README.txt (the "-Dv" option is now correctly recognised, instead of "-Dn")
               -- corrected a misleading part of text in README.txt (about the step length, in the "-N" description)
               -- added a cutoff to the heteronuclear nonadiabatic potential ("--cutoff" parameter)
               -- added an option to display results in MHz ("--mhz" parameter)
               -- minor output subroutine rework
               -- the "-h" option now prints only the essential part of README.txt (up to "Contents of this directory:")

h2spectre_7.0.1-- more information to code comments and README.txt added
               -- bigger numerical error estimate for the heteronuclear contribution (should still be small enough not to affect final error bars for E(2))
               -- minor changes in the E(5,0)(R) long-distance asymptotics (shouldn't even be observable in results)
               -- minor editorial changes

h2spectre_7.0  -- references to the paper updated after its official publication in Phys. Rev. A:
                  J. Komasa, M. Puchalski, P. Czachorowski, G. Lach, K. Pachucki, Phys. Rev. A 100, 032519 (2019)                 
               -- minor editorial changes
               -- several levels, which had mistakenly been rejected a'priori before as unbound, are now possible to be calculated
               -- user is now able to force the calculation for a level which is not known to be bound ("-Dn" option)

h2spectre_6.5  -- a minor change in name of the package ("h2spectre" instead of "h2spectr")
               -- a minor change in the E(5,0)(R) long-distance fit
               -- numerical error estimates in "data/h2spectr_pot.f90" corrected
               -- updated points and fit for the heteronuclear correction
               -- added numerical error estimate for the heteronuclear correction
               -- added "--std=legacy" to PPPACK compilation options in Makefile (to handle the warnings about the Fortran 2018 obsolete features)
               -- added references to the paper J. Komasa, M. Puchalski, P. Czachorowski, G. Lach, K. Pachucki, Phys. Rev. A (submitted 2019)
               -- increased verbosity of comments in the code
               -- missing references added
               -- a few more minor editorial changes in several files

h2spectr_6.0   -- the first publicly released version
