+* Publishing and “stable” tagging are now restricted to the `main` branch, preventing accidental releases from other branches
+* Stale CI runs are automatically cancelled, reducing wasted resources and speeding up feedback cycles
+* Overall CI reliability and security posture improved, with fewer false positives and more consistent pipeline results

 %changelog
+* Thu Mar 26 2026 Kevin Veen-Birkenbach <kevin@veen.world> - 1.13.3-1
+- CI pipelines now include automated security scanning (CodeQL, Docker lint), increasing detection of vulnerabilities and misconfigurations
+* Workflow permissions were tightened and fixed, ensuring secure and reliable execution of reusable workflows
+* Publishing and “stable” tagging are now restricted to the `main` branch, preventing accidental releases from other branches
+* Stale CI runs are automatically cancelled, reducing wasted resources and speeding up feedback cycles
+* Overall CI reliability and security posture improved, with fewer false positives and more consistent pipeline results
+
+* Thu Mar 26 2026 Kevin Veen-Birkenbach <kevin@veen.world> - 1.13.2-1
+- Fail fast with a clear error when the Nix bootstrap or nix binary is unavailable instead of continuing with a broken startup path.
+
 * Fri Mar 20 2026 Kevin Veen-Birkenbach <kevin@veen.world> - 1.13.1-1
 - Fixed misleading GPG verification failures by adding explicit git and gnupg runtime dependencies and surfacing signing-key lookup errors accurately.
