[0.3.0] - unreleased (release candidate)

Current version. Package maturity: Beta. No Stable/1.0 claim is made.

Added

• Strict empyrical 0.6.0 compatibility layer (fincore.empyrical): 54/54 public symbols (C0), 49/49 callables (C1), core callables C3.
• Pyfolio 0.9.6-profile façade (fincore.pyfolio): 11 workflows C1, risk/returns/perf-attrib/full-sheet main chains C4.
• Functional extras: pyfolio, interactive, report-pdf, report-xlsx, bayesian, data-yahoo, data-alphavantage, data-pandas-datareader, data-cn.
• Enhanced validation exceptions and AnalysisContext snapshot semantics (replace_data(), cache invalidation, immunity to caller-side mutation).
• Machine-generated quality baseline and CI release gates.

Changed

• Python 3.11+ required (breaking change vs empyrical).
• Flat API remains bound to enhanced fincore.metrics semantics in 0.3.x.

Fixed

• Drawdown tear sheets with fewer drawdowns than top-N (no NaT ConversionError).
• Wide/stacked perf-attrib equivalence; attribution identity holds across date gaps.
• Lossless legacy/canonical transaction normalization.
• No Matplotlib backend mutation on import; no package-dir writes from compatibility workflows.

Historical snapshot (not release evidence)

An earlier planning document labeled 1.0.0 - 2025-02-18 (including a "100% test coverage" claim) is retained in CHANGELOG.md purely as a historical snapshot. Its numbers are not current acceptance evidence; the repository has no 1.0.0 release.
