+## v0.1.36 (21/08/2026)
+
+- Fixed several binary and time-dependent curve consistency issues, including cutoff-grid endpoints, binary cutoff equality, time-dependent reference prevalence, gains perfect-reference behavior, custom colors, and plot sizing.
+- Added stricter validation for probability/outcome domains and multi-population input alignment, and made binary/time-dependent performance-data ordering and column schemas deterministic.
+- Updated time-dependent calibration defaults to use the adjusted-censoring / competing-as-negative heuristic set when omitted, while rejecting ambiguous multiple heuristic sets.
+- Moved secondary-Cox and LOWESS calibration smoothing onto `smoothstate`, removing obsolete runtime dependencies including `statsmodels`, `pandas`, `pyarrow`, `typing`, and runtime `marimo`.
+- Added Plotly 6 support and raised the supported Python range to 3.12–3.14, with CI now enforcing Ruff lint/formatting and `ty` type checking across the supported interpreters.
+- Improved package metadata and project links, and upgraded the documentation toolchain to Great Docs 0.15.0.
+
 ## v0.1.33
 
 - Extended `smooth_method="secondary_cox"` in `create_calibration_curve_times` to use 3-knot restricted cubic splines (RCS) on complementary log-log predictions.
