Changes in version 0.2.1 (2026-11-10) - Fix the README license link so that its target is present in the built source package. - Cite the published turnover-based cost-distribution recurrence and distinguish it from the package-specific retention and price-allocation choices. Changes in version 0.2.0 - Validate calendar dates, column mappings, numeric input, stock selection, turnover units, adjustment factors and grid resource limits. - Reject material VWAP inconsistencies instead of clipping their cost prices; record minor rounding adjustments explicitly. - Separate profitable, break-even and loss shares. All returned positive weights are preserved. Uniform allocation uses price-cell overlap. - Add an optional initial distribution, report surviving initial weight, flag circulating-share changes and clarify first-day initialization. - Add offline prepare_tushare_data() and chip_mean_cost(). - Add summary and data-frame methods, customizable plots, complete English reference pages, a worked vignette, Chinese guidance and regression tests. - Replace provisional author metadata with the maintainer's supplied details. Changes in version 0.1.0 - Initial local prototype of a daily turnover-replacement estimator.
