[DFTB+ Announce] DFTB+ 20.2 released

[Bálint Aradi]

Dear DFTB+ community,

We are pleased to announce the next stable version (Release 20.2).
Thanks to the work of those contributing to the code, this version again
contains several major improvements. These include

* Many body and Tkatchenko-Scheffler dispersion models

* Delta DFTB for the lowest singlet excitated state of closed shell systems

* Electron transport for system with (colinear) spin polarisation, plus
Green's function embedding for the surfaces of magnetic systems

* A new code for phonon transport calculations

* Linear response excited state forces for spin polarised systems

* The FIRE geometry optimiser and improvements to the LBFGS optimiser

We would like to thank you for all your feedback and contributions
which shaped this release. We hope you will find DFTB+ 20.2 useful
for your scientific work and are looking forward to further comments,
suggestions and contributions in the future.


The DFTB+ developers


Ps. Please also look out for news about the upcoming release of our
Slater-Koster generation tools in the next weeks.
