January 2017

• Python CAMB wrapper correlations module:
  • Transform between CL and CMB correlation functions
  • Lensed power spectra and correlation functions from unlensed spectra and lensing power spectrum (useful for delensing)
  • Matrix of derivatives of lensed power spectra with respect to lensing power and unlensed CL
• Added halofit_casarini=7 for PKequal dark energy fitting (thanks Luciano Casarini; arXiv:0810.0190, arXiv:1601.07230)
• Fixed compilation issue with gfortran 6.3

November 2016

• CAMB_SetNeutrinoHierarchy function and python wrapper neutrino_hierarchy option for set_cosmology function (to configure to use two eigenstate approximation to normal or inverted hierarchies)
• Various misc small bug fixes, improvements and compiler compatibility changes

May 2016

• Added support for HMCODE Halofit version (halofit_version=5; thanks Alex Mead); Takahashi remains the default as before
• Python CAMB
  • camb.get_matter_power_interpolator function to get 2D spline object for evaluating P(k,z);
    See the sample notebook for an example of how to use this to calculate a lensing spectrum
  • Result object functions to get unsplined matter power (get_linear_matter_power_spectrum,get_nonlinear_matter_power_spectrum)
  • Result object function to get redshift from conformal time (redshift_at_comoving_radial_distance)
  • camb.set_halofit_version to set halofit version;
  • Option to set cosmomc_theta rather than H_0 (thanks Marius Millea)
  • Wigner 3j function for convenience (camb.bispectrum.threej).
