Compared to the original EAGLE runs of Schaye et al. 2015),
the following changes have been made (at standard resolution):
- The flavour of SPH has been changed from the Pressure-Entropy
"ANARCHY" implementation to the Density-energy based "SPHENIX"
implementation of Borrow+20.
- The dark matter softening lengths have been increased to 1.3
pkpc and 3.32 ckpc. The comoving baryon softening lengths have
been changed to 1.79 ckpc. This follows the recommendations of
Ludlow et al. 2019. Old values were 0.7 pkpc and 2.69 ckpc for
all the particle species.
- SPH particles with a mass larger than 7*10^6 Msun (~4x the initial
gas particle mass) are now split into 2 equal mass particles
within the smoothing length of the original particle.
- SPH particles reaching a mass larger than 7*10^6 Msun (~4x the
initial gas particle mass) are now split into 2 equal mass

- The metallicity-dependent density threshold for star formation
uses the smoothed metallicities and not the raw metallicities
any more.
