Added Planck 2018 likelihoods and associated files.
Minor updated Pantheon (batch3/Pantheon18.ini)
batch3/HST_Riess19.ini for latest H0
Add DR14 Lyman-alpha BAO (thanks Pablo-Lemos)
Bug fixes and misc compatibility improvements
Updated to latest GetDist
GetDist GUI supports Python 3 with PySide2
Updated to CAMB version 1.0.7. (note that this changes likelihood values slightly compared to Planck2018 branch; also HMcode version changes for numerical stability and speed)

See the Planck2018 branch for fixed version consistent with that used for release (uses CAMB July 2018).

Note that the zipped downloads below do not include the CAMB submodule, usually it is easier to clone the repository using git clone --recursive.

Added .derived_ranges files (in /paramnames folder) to specify hard priors on derived parameters. These are now propagated to output chain .ranges file along with H0 and z_rei priors (and hence limits do not need to be manually specified when running GetDist).
Added neutrino_hierarchy (={normal, inverted, degenerate}), to support one or two distinct eigenstate approximation to oscillation constraints.
Bicep BK14 data files and CMB_BK_Planck update (thanks Colin Bischoff)
Support for BAO .dataset files with no measurement_type keyword (set in data file for each point instead)
Updated getdist to 0.2.6 (fixing compatibility issue with latest matplotlib for 2D contours)
Update CAMB to Nov 2016 version
