Many bugfixes -- special thanks to Guadalupe Cañas-Herrera and Vivian Miranda!
I/O
- More permissive resuming.
Parameterization and priors
- Made possible to fix a parameter whose only role is being an argument of a dynamically
defined one.
- Likelihoods can be used in dynamical derived parameters as `chi2__[name]` (cosmological
application: added automatic consolidated CMB and BAO likelihoods).
Samplers
General
- Seeded runs for `evaluate`, `mcmc` and `polychord`.
MCMC
- Small improvements to callback functions.
PolyChord
- Updated to PolyChord 1.15 and using
the [official GitHub repo](https://github.com/PolyChord/PolyChordLite).
- Fixed output: now -logposterior is actually that (was chi squared of posterior).
- Interfaced callback functions.
Likelihoods
Created `gaussian_mixture` and added deprecation notice to `gaussian`
Cosmological theory codes
General
- Added P(k) interpolator as an observable (was already available for CAMB, but not
documented)
classy
- Updated to 2.7.1
- Added P(k) interpolator
Cosmological likelihoods
DES
- Added Y1 release likelihoods [(arXiv:1708.01530)](https://arxiv.org/abs/1708.01530)
BICEP-Keck
- Updated to 2015 data [(arXiv:1810.05216)](https://arxiv.org/abs/1810.05216) and renamed
to `bicep_keck_2015`.
