v1.0 -- First release

This is the first release of FAST++, which is feature complete. Compared to FAST, this version includes:

• Custom star formation histories
• Priors on the total infrared luminosity
• More output options (average SFR over given timescale, ionizing luminosity, dust luminosity, formed stellar mass ...)

NB: The software will progressively diverge from the behavior of the original FAST, as new features are included and flaws are corrected. If you are interested in the speedups and reduced memory usage, but want to keep the behavior of the old FAST, look for "legacy" releases.

v1.3 [LEGACY] -- Fixed incorrect z intervals with BEST_AT_ZPHOT and simulations

This release fixes a bug where the redshift confidence intervals were ignored in Monte Carlo simulations when BEST_AT_ZPHOT=1. An incorrect error message was also removed, when a galaxy had a zspec which is outside of the zphot confidence intervals (this does not matter, because only z=zspec will be used anyway).

NB: This is a "legacy" release. These versions of FAST++ are meant to reproduce the behavior of the old FAST and not introduce any other feature. If you want more fancy options and updated stuff, look for a non-legacy release.

v1.2 [LEGACY] -- Fixed bug and crashes when reading spectra

This "bug fix" release addresses issues with the parsing of the spectrum file (*.spec). Some bug in the code was making FAST++ crash, and prevented the program from fitting the galaxies for which no spectrum was provided. Runs which did not use a spectrum file were not affected. These aspects of the code have now been properly tested, and all work as intended.

NB: This is a "legacy" release. These versions of FAST++ are meant to reproduce the behavior of the old FAST and not introduce any other feature. If you want more fancy options and updated stuff, look for a non-legacy release.

v1.1 [LEGACY] -- Fixed treatment of photo-z and spec-z

This releases fixes a rare bug in the treatment of galaxies which have a photo-z or a spec-z that falls outside of the chosen confidence interval from EAzY. The bug was that such galaxies were never attributed any best fit, because no model was able to satisfy both the confidence interval constraint and the spec-z or photo-z. This is now corrected.

Galaxies with spec-z (or photo-z with FORCE_ZPHOT=1) now have their confidence interval narrowed down to this chosen redshift, so both best-fit parameters and their confidence intervals will correspond to this fixed redshift.

Galaxies with photo-z outside of the confidence interval (with BEST_AT_ZPHOT=1) are now "properly" given a best fit and uncertainties. In this later case, the best-fit solution will be evaluated at the given photo-z, and the confidence intervals for best-fit parameters will instead follow the redshift confidence interval, as for the other galaxies. This will lead to a mismatch between the two, and as such will be difficult to interpret. But this is a problem created by the user in the first place: having a photo-z outside of the confidence interval makes no sense. The only reason FAST++ tolerates this is for compatibility with FAST-IDL, and a warning will be issued so the user can identify such cases and fix them.

NB: This is a "legacy" release. These versions of FAST++ are meant to reproduce the behavior of the old FAST and not introduce any other feature. If you want more fancy options and updated stuff, look for a non-legacy release.

v1.0 [LEGACY] -- Feature complete "legacy" release, drop-in replacement for FAST

This release contains all the features of FAST, and will reproduce its output almost perfectly.

NB: This is a "legacy" release. These versions of FAST++ are meant to reproduce the behavior of the old FAST and not introduce any other feature. If you want more fancy options and updated stuff, look for a non-legacy release.
