What's Changed

Major Changes 🛠

• Removed support for selectively tracking variables via pm.sample(trace=[...]). by @michaelosthege in #6269
• Do not rely on tag information for rv and logp conversions by @ricardoV94 in #6281. This includes:
  • Deprecated accessing any of [value_variable|observations|transform|total_size] via var.tag in favor of model.rvs_to_[values|transforms|total_sizes]
  • Deprecated joint_logp in favor of model.logp
  • Deprecated aesaraf.rvs_to_value_vars in favor of model.replace_rvs_by_values
• Using keyword seed for initial point no longer supported by @wd60622 in #6291
• Sampling of transformed variables from prior_predictive is no longer allowed by @ricardoV94 in #6309
• Require all step methods to return stats by @michaelosthege in #6313. This includes
  • Require all step methods to return stats from their step/astep method.
  • The BlockedStep.generates_stats attribute was removed.
