+## 4.15.2
+
+### Enhancements
+
+- Improves Apple Search Ads attribution capture rate.
+- Filters out the all-zeros IDFA sentinel (returned when App Tracking Transparency is denied) so it no longer pollutes the `idfa` attribute on attribution payloads.
+
+### Fixes
+
+- Changes the Superscript spm package repo source to a new lightweight repo meaning that the download of the package is way faster.
