1.5.3

• CAMBparams can now be saved and restored using repr/eval or pickle in standard cases
• Allow DE fluid w(a) table models with w<-1 as long as do not cross -1
• Removed camb.py
• Misc tidies and compatibility fixes

1.5.1

• Refactor reionization models allowing setting the model via python; added sample ExpReionization alternative to default tanh. Examples added to example notebook.
• Removed dependency on distutils ready for Python 12

1.5.0

• Fixed bug calculating Cl from time sources that affected iterated use in Cobaya
• Increase max transfer redshifts to 256
• Added min_l_logl_sampling parameter to set_accuracy (to set lowest multipole at which sparse log-L sampling is used)
• Added sample transfer function animations to the end of the example notebook

1.4.0

• Updated numerical constants, use latest definitions for Megaparsec, and calculate times in Julian giga-years
• Updated default nnu to 3.044 (from 3.046)
• Updated default BBN model (for helium abundance) to PRIMAT2021
• Support general bias(k,z) for source window functions
• Fix for HMcode-2020 feedback at low k
• Fix get_matter_power_spectrum for cross-spectra
• Allow read_ini to load directly from a URL
• Minor code tidies

These changes do change numerical results, but only at a level that is irrelevant for near-future observations. But some of the higher-precision unit tests also had to be updated.

1.3.6

• add optional nonlinear parameter to set_for_lmax
• add 21cm transfer variable names to python; add example notebook example
• recfast compatibility with very different T_0
• Minor code and doc fixes/warnings

1.3.5

• angular_diameter_distance2 fix and allow for vector arguments
• Support vector arguments for physical_time, physical_time_a1_a2 and conformal_time_a1_a2
• Fixes and error checking for some obscure corner cases
• More robust to passing in non-contiguous or 32 bit vector arguments

1.3.2

• Source window functions now support bias(z) from Python interface (see sample notebook)
• get_partially_lensed_cls allows A_lens as function of L
• get_lensed_gradient_cls optionally supports using custom lensing spectrum input
• Added updated PRIMAT BBN interpolation table PRIMAT_Yp_DH_ErrorMC_2021.dat (thanks Cyril Pitrou)
• Added HMCode unit tests (thanks Alex Mead)
• Minor compatibility fixes

1.3.0

• Added HMCode 2020 and now default (thanks Alex Mead, arXiv:2009.01858)
• Raise error for w+wa>0 in dark energy models
• Added get_lensed_cls_with_spectrum and get_partially_lensed_cls for partially delensed and Alens-scaled lensed spectra
• Added correlation function and partial delensing examples to example notebook

1.2.0

• Quintessence dark energy support updated (from very old) and merged. Example implementation of early dark energy. In general, new models require deriving a new inherited quintessence class in Fortran and Python.
• Lensing and f_NL bispectrum code updated to work with latest version (no Python interface)
• Bug fixes for get_sigmaR and other small bug fixes/additional warnings.

1.1.3

• Correct get_valid_numerical_params
• Sympy 1.6 compatibility
• mathutils functions for polarization Pseudo-CL couplings and better doc
