v0.14.0

• New flexible interface API (#378). This is going to be a breaking change for users of
  the flexible interface and you will have to change your code. Old syntax:

from sbi.inference import SNPE, prepare_for_sbi

simulator, prior = prepare_for_sbi(simulator, prior)
inference = SNPE(simulator, prior)

# Simulate, train, and build posterior.
posterior = inference(num_simulation=1000)

New syntax:

from sbi.inference import SNPE, prepare_for_sbi, simulate_for_sbi

simulator, prior = prepare_for_sbi(simulator, prior)
inference = SNPE(prior)

theta, x = simulate_for_sbi(simulator, proposal=prior, num_simulations=1000)
density_estimator = inference.append_simulations(theta, x).train()
posterior = inference.build_posterior(density_estimator)  # MCMC kwargs go here.

• Fixed typo in docs for infer (thanks @glouppe, #370)
• New RestrictionEstimator to learn regions of bad simulation outputs (#390)
• Improvements for and new ABC methods (#395)
  • Linear regression adjustment as in Beaumont et al. 2002 for both MCABC and SMCABC
  • Semi-automatic summary statistics as in Fearnhead & Prangle 2012 for both MCABC and SMCABC
  • Small fixes to perturbation kernel covariance estimation in SMCABC.
