## 5.4.0

September 2, 2026

### New Features

**Holdout Targeted Delivery Exclusion**: Holdouts can now be configured to exclude Targeted Delivery rules, so users held out of experiments still receive their Targeted Delivery experiences. This gives you a cleaner measure of experiment impact without holding users back from ongoing rollouts.

- Upgrade dependency to [Java SDK 4.6.0](https://github.com/optimizely/java-sdk/releases/tag/4.6.0)

### Fixes

- Fix Jackson serializer NoClassDefFoundError when R8 obfuscates naming strategy fields ([#539](https://github.com/optimizely/android-sdk/pull/539))
