+ - The cooling uses the Ploeckinger+20 tables including an updated
+   UV background, newer version of CLOUDY and self-shielding
+   (was using the Wiersma+09 tables before).
  - The redshift of H reionization has been lowered to 7.5 (from 11.5).
+ - The entropy floor between n_H = 10^-5 and 10^-1 cm^3 at 8000K has
+   been removed as the new cooling tables handle this correctly. The
+   gamma=4/3 floor has been extended to lower densities
+   (i.e. 800K at n_H = 10^-4 cm^-3) as a fail-safe.
+ - Particles can be star-forming if they are within 0.3 dex of the
+   entropy floor (was 0.5 dex). These particles also get their
+   subgrid properties (rho, T) computed.
  - The minimal mass of SNII stars has been raised to 8 Msun (from 6).
  - The SNII feedback delay is done by sampling the stellar age
    distribution and not using a fixed delay of 30 Myr any more.
+ - The halo mass for BH seeding has been lowered to 10^10 M_sun
+   (from 10^10/h Msun).
  - The black hole accretion rate is now limited to 100% of the
    Eddington rate (from 100/h = 150 %).
  - The circular velocity threshold for BH mergers is measured
    at the actual distance linking the BHs not at the kernel support
    length any more.
+ - The BHs can reposition only onto gas particles and not onto any
+   type as before.
+ - The maximal relative velocity between a BH and gas particle
+   eligible to be a reposition target has been increased to 0.5 times
+   the local sound-speed around the BH (was 0.25 * c_sound).
