-| 4.1     | 2026-03-22 | AST context overhaul (v0.5.0): full signature extraction from tree-sitter nodes, semantic change classification (whitespace vs body vs signature), old→new signature diffs, cross-file connection detection, formatting auto-detection via symbols. 367 tests. |

 | 4.0     | 2026-03-13 | PRD normalization: aligned phases with shipped versions (v0.2.0/v0.3.x/v0.4.0), collapsed revision history, unified status markers, resolved stale critical issues, canonicalized test count to 308, removed dead cross-references. FR-031 (Exclude Files) and FR-033 (Copy to Clipboard) shipped. |
