The important new features and changes are as follows.

1) New reduced-cost CC2 and ADC(2) approaches.
2) Interface to the Amber molecular dynamics package, which enables QM/MM calculations.
3) Interface to the Libxc library, which enables the use of hundreds of density functionals.
4) Spin-component scaled dRPA75 (SCS-dRPA75) method.
5) Analytic gradients for double-hybrid density functional methods.
6) Improved three-center two-electron integral integral code.
