 # Changelog
 
+## 1.5.3 - 2025-12-31
+
+### CI/CD Updates
+
+- Moved SBOM generation from `sbom.yml` workflow to `build.yml` workflow as release assets instead of auto-committing to source code
+- Removed SPDX format, now only generating CycloneDX SBOM format (more popular and security-focused)
+
+### UI/UX
+
+- Updated version display logic: tag builds show tag version (e.g., `v1.5.2`), branch builds show commit SHA (e.g., `abc1234`), local dev shows `dev`
