Description
⚠️ Breaking Changes
- Make PyMC and Pyro optional dependencies (#1835):
pip install sbino longer installspymcorpyro-ppl. Users who need Pyro or PyMC MCMC samplers should install extras:pip install "sbi[pyro]"for Pyro samplers (hmc_pyro,nuts_pyro)pip install "sbi[pymc]"for PyMC samplers (slice_pymc,hmc_pymc,nuts_pymc)pip install "sbi[all]"for both- Using a Pyro/PyMC method without the dependency installed raises a clear
ImportErrorwith install instructions.
🐛 Bug Fixes
- Fix TARP z-scoring bug (#1832): Reference points are now z-scored alongside
thetasandposterior_sampleswhenz_score_theta=True, fixing incorrect distance calculations that masked bias detection. - Fix broken
biased_toy_gaussiantest helper: Rewrote to create actual location bias (posterior mean shifted from truth) instead of the previous NaN-producing formula.
📖 Documentation
- Streamlined README installation section, recommend
uvas default. - Added optional dependency install instructions to README, installation guide, and relevant tutorials.
🔧 Improvements
- Change default
num_binsin TARP:run_tarpand_run_tarpnow default tonum_bins=None(auto-scales tonum_sims // 10) instead of the hardcoded30, improving KS test power for larger sample sizes.
🔒 Security
- Added SLSA build provenance attestations to the release workflow.
- Added Dependabot for automated GitHub Actions version updates.
- Added
SECURITY.mdwith vulnerability disclosure policy. - Fixed release uploads with
--clobberflag.
