Summary of the most important changes:

Major infrastructure changes
- Exact Pythia version is now required
- No debug output in the default build type, which results in much better performance
New features
- Particle properties updated to use PDG 2018 data (this includes 5 new N and a new Delta)
- Lund fragmentation function for leading baryons in soft non-diffractive string processes
- Support for customized nuclei: optionally reading in initial nucleon positions in collider modus
- New density type for charge/isospin and possibility to output the charge currents without smearing
- Option to place a single high-momentum particle in the center of the sphere modus (~jet)
Bug fixes/Minor changes
- Documentation of formation time
- Continuous particle formation for unformed particles from string fragmentation processes
- Correct generic radius for nuclei with A > 16, except for Au, Pb, U, Cu as they are/were exactly specified
- Correct declaration of Woods-Saxon distribution for deformed nuclei
- Bug fixes related to formation of particles including
  - Correcting the boost
  - Adjust resonance decay times
  - Add unformed particles to grid for collision finding, if they form during the time step
- SMASH compiles now also with GCC >= 9, Clang >= 7
- Fix thermodynamic VTK output of the Landau velocity
