 Full release notes with details on each version: [GitHub Releases](https://github.com/safishamsi/graphify/releases)
 
+## 0.3.24 (2026-04-09)
+
+- Fix: `graphify codex install` (and opencode) no longer exits early when `AGENTS.md` already has the graphify section — partial installs with a missing `.codex/hooks.json` can now recover on re-run (#153)
+
 ## 0.3.23 (2026-04-09)
 
 - Add: Gemini CLI support — `graphify gemini install` writes a `GEMINI.md` section and a `BeforeTool` hook in `.gemini/settings.json` that fires before file-read tool calls (#105)
