 Setup
 ~~~~~
 - major reorganisation of star setup into separate module, can now setup and relax one or more stars in several different setups, allowing one-shot-setup-and-relax for common envelopes, binary stars and tidal disruption events (#405,#407,#413)
-- new hierarchical system setup: can now setup an arbitrary number of point masses or stars in hierarchical systems (thanks to Simone Ceppi; #401,#426)

 - relaxation process for stars is restartable, works automatically (#414, #417)
 - can setup unbound parabolic and hyperbolic orbits using the standard 6-parameter orbital elements (#443,#448; #302)
 - use m1 and m2 in the binary disc setup instead of primary mass and mass ratio (#431)

 - cleanup and further enhancements to common envelope analysis routines (thanks to Miguel Gonzalez-Bolivar; #467,#462)
 - moddump_sink displays correct value of sink luminosity (#439)
 - analysis routine for radio emission from tidal disruption events (thanks to Fitz Hu; #472)
