2.0f ==> 2.0g

o Fixed problem with sinAmB in Ann_zh_ZH_cross.c, based on report
  from J. Feng. This must be correct, because the previous
  code was inconsistent between sinAmB and cosAmB. Feng reports
  that the fixed code behaves as expected, with the correct
  unitarity cancellation.

o Added capture equilibration time outputs (tau_A for sun and earth).

o Dialed up the coannihilation cutoff parameter to 1.50,
  based on a report from Andreas Birkedal-Hansen.


2.0e ==> 2.0f

o Fix off-by-one error in numerical integration. This corrects
  a problem in the indirect detection calculation. Thanks to
  D. Hooper for pointing out the problem with the muon fluxes.


2.0d ==> 2.0e

o Added comment to Detector.in indicating the problem with
  neutrino_threshold_GeV. Thanks to S. Cartwright for bringing it up.

o Fixed problem with chargino diagonalization. Thanks to C. Kolda.

o Converted to GNU autoconf and moved source files out of
  directories to pacify automake.


1.x ==> 2.0

o Added LEP neutralino pair and chargino pair production cross-sections.
  See ee_chargcharg.h, ee_neutneut.h

o Added LEP Higgs production cross-section (Bjorken process, e+e- --> h bar(f) f).
  See higgs_production.h

o Added LEP sfermion pair production cross-sections.
  See ee_sfsf.h

o Added chargino-neutralino co-annihilation to the
  relic density calculation, including f-fbar and gamma-W
  final states.
  See neut_charg_ff.h and neut_charg_gammaW.h if interested
  in the interface to these functions.

o Fixed errors in gg and 2-photon amplitudes due to sign
  error in one term of real part of box diagram, as
  indicated by Bergstrom+Ullio. This term was re-implemented
  in terms of the more robust and compact dilogarithm representation
  as well.

o Added full one-loop W-boson contribution to 2-photon amplitude,
  using results of Bergstrom+Ullio.
  
o Compilation process now specifically generates an object
  library, called libneut.a. This was promised in version 1.x,
  but never explicitly delivered.

o Removed all model specifications other than what was
  called "generic" in version 1.x. The rationale is as follows.
  - The "simplified" model scheme was created only for early testing
  of the code by comparison with previous results. It was
  a physically inconsistent scheme, and was never intended
  for production use.
  - The "practical" model was a proper subset of "generic", which was
  intended to be easier to understand than the full "generic"
  scheme. However, no simplification in practical use was found.
  - The "sugra" model scheme was not physically complete, and failed
  to be correct or stable in some regions of parameter space. It was
  intended as an illustration of the use of the physics functions
  but was not meant for production use. In the name of safety and
  correctness, it has been removed. All serious supergravity studies
  would in any case have required external generation of input
  data.

o Complete re-working of output format. Automatic generation
  of output formatting (column choices, etc.), with associated
  guide file which provides a human- and machine-readable
  description of the data layout. This allows general programs
  to parse the guide file and automatically extract information
  without knowledge of how the data was generated. In 1.x versions,
  the output data layout was dependent on the type of program run,
  in an irregular way.

o The removal of extraneous model schemes and uniformization of
  the output format allow the 'neut' executable to be used as
  a batch engine, with automated generation of input data and
  automated analysis of output data.
