- Introduced Breaking changes section and renamed several core concepts for clarity.
- Renamed distributions: Additive (Normal), Multiplic (Log-Normal), Power (Pareto).
- Changed primary measures: Center replaces Mean, Spread replaces StdDev, Disparity replaces Cohen’s d.
- Added new section on Distributions (Additive, Multiplic, Exponential, Power, Uniform).
- Added new section on Properties (Breakdown, Drift, Invariance).
- Reworked statistical efficiency into new Drift framework.
- Added new Methodology section (assumptions → conditions, efficiency → drift).
- Added Algorithms section with O(n log n) implementations of Center and Spread.
- Expanded Studies with updated proofs and examples, including new Drift-based analysis.
- Revised Introductory material (Desiderata, Primer, Definitions) for consistency and clarity.
- Updated estimator definitions with complexity notes, asymptotic behavior, and improved domain clarifications.
- Marked Disparity explicitly as “robust effect size” throughout.
