## \[2.6.0] - 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.

- Add holdout exclude\_targeted\_deliveries support ([#458](https://github.com/optimizely/go-sdk/pull/458))
