21cmFAST v2.1

This release includes the latest source model descriptions, allowing for power law scalings in the typical galaxy properties, including the stellar to halo mass relation and ionizing photon escape fraction.

21cmFAST v2.0

New, flexible model for astrophysical sources and sinks of photons. This version facilitates direct comparison to UV luminosity function observations. For more details see

21cmFAST_v1.3

Added support for inhomogeneous recombinations, following the prescription of Sobacchi & Mesinger (2014). Note that photo-heating feedback is not implemented in this release. Legibility of find_HII_bubbles.c has also improved, as well as the features in sliceplot.py.

21cmFAST_v1.2

This is the public version of the semi-numerical, cosmological simulation code 21cmFAST (Mesinger & Furlanetto 2007; Mesinger et al. 2011). New in v1.2 is explicit support for a halo mass dependent ionization efficiency. Please see the version history file for details.
