v0.6.3 - Solver-related improvements
This release includes all changes since 0.6.1, covering both 0.6.2 and 0.6.3.
Highlights
- Added a public power-fit problem/result API via
build_power_fit_problem(...)andbuild_power_fit_result(...), making it easier to export problems, test external solvers, and repackage results into standardPowerWeightFitResultobjects. - Added richer diagnostics and exports, including
edge_diagnosticsand objective breakdown reporting. - Improved native ADMM/Huber fitting with a better splitting formulation, analytic warm starts, and fixes for sparse-outlier cases that previously stalled or diverged.
- Centralized core power-fit formulas in a shared problem/evaluation layer, reducing internal formula drift and simplifying solver/report internals.
- Expanded regression coverage for both the robust-fit path and the new public problem API.
