+## 0.6.4 (2026-05-02)

+- Fix: Codex PreToolUse hook failed on Windows — `[ -f ]` is bash-only and crashes on `cmd.exe`; replaced with a cross-platform Python one-liner (`pathlib.Path.exists()`) (#651)
+
 ## 0.6.3 (2026-05-02)
 
 - Fix: incremental rebuild (`graphify update`, post-commit hook) dropped INFERRED/AMBIGUOUS semantic nodes extracted from code files — node preservation now filters by ID membership in the new AST output instead of `file_type`, so LLM-extracted call/data-flow edges survive code-only rebuilds (#653)
