    • Adds JAX support for tfd.Zipf
    • Adds Implicit Reparameterization Gradients to tfd.InverseGaussian.
    • Adds quantiles for tfd.{Chi2,ExpGamma,Gamma,GeneralizedNormal,InverseGamma}
    • Derive Distribution batch shapes automatically from parameter annotations.
    • Ensuring Exponential.cdf(x) is always 0 for x < 0.
    • VectorExponentialLinearOperator and VectorExponentialDiag distributions now return variance, covariance, and standard deviation of the correct shape.
    • Bates distribution now returns mean of the correct shape.
    • GeneralizedPareto now returns variance of the correct shape.
    • Deterministic distribution now returns mean, mode, and variance of the correct shape.
    • Ensure that JointDistributionPinned's support bijectors respect autobatching.
    • Now systematically testing log_probs of most distributions for numerical accuracy.
    • InverseGaussian no longer emits negative samples for large loc / concentration
    • GammaGamma, GeneralizedExtremeValue, LogLogistic, LogNormal, ProbitBernoulli should no longer compute nan log_probs on their own samples. VonMisesFisher, Pareto, and GeneralizedExtremeValue should no longer emit samples numerically outside their support.
    • Improve numerical stability of tfd.ContinuousBernoulli and deprecate lims parameter.

  • Bijectors

    • Add bijectors to mimic tf.nest.flatten (tfb.tree_flatten) and tf.nest.pack_sequence_as (tfb.pack_sequence_as).
    • Adds tfp.experimental.bijectors.Sharded
    • Remove deprecated tfb.ScaleTrilL. Use tfb.FillScaleTriL instead.
    • Adds cls.parameter_properties() annotations for Bijectors.
    • Extend range tfb.Power to all reals for odd integer powers.
    • Infer the log-deg-jacobian of scalar bijectors using autodiff, if not otherwise specified.

  • MCMC

    • MCMC diagnostics support arbitrary structures of states, not just lists.
    • remc_thermodynamic_integrals added to tfp.experimental.mcmc
    • Adds tfp.experimental.mcmc.windowed_adaptive_hmc
    • Adds an experimental API for initializing a Markov chain from a near-zero uniform distribution in unconstrained space. tfp.experimental.mcmc.init_near_unconstrained_zero
    • Adds an experimental utility for retrying Markov Chain initialization until an acceptable point is found. tfp.experimental.mcmc.retry_init
    • Shuffling experimental streaming MCMC API to slot into tfp.mcmc with a minimum of disruption.
    • Adds ThinningKernel to experimental.mcmc.
    • Adds experimental.mcmc.run_kernel driver as a candidate streaming-based replacement to mcmc.sample_chain

  • VI

    • Adds build_split_flow_surrogate_posterior to tfp.experimental.vi to build structured VI surrogate posteriors from normalizing flows.
    • Adds build_affine_surrogate_posterior to tfp.experimental.vi for construction of ADVI surrogate posteriors from an event shape.
    • Adds build_affine_surrogate_posterior_from_base_distribution to tfp.experimental.vi to enable construction of ADVI surrogate posteriors with correlation structures induced by affine transformations.

  • MAP/MLE

    • Added convenience method tfp.experimental.util.make_trainable(cls) to create trainable instances of distributions and bijectors.

  • Math/linalg

    • tfp.stats.windowed_variance efficiently and accurately computes windowed variances.
    • tfp.stats.cumulative_variance efficiently and accurately computes cumulative variances.
    • RunningCovariance and friends can now be initialized from an example Tensor, not just from explicit shape and dtype.
    • Cleaner API for RunningCentralMoments, RunningMean, RunningPotentialScaleReduction.

  • STS

    • Speed up STS forecasting and decomposition using internal tf.function wrapping.
    • Add option to speed up filtering in LinearGaussianSSM when only the final step's results are required.
