**Added**

* **Parameterized modules.** Modules take parameters, so one module covers several variations. Values are passed by value at the call site. See [Modules](/writing-tests/modules.md).
* **Datasets and variables.** Test data can be defined as a dataset and bound to a test plan at run time, referenced in scripts as `{{var}}`. Nesting is limited to two levels. Lockable pools lease a row exclusively to one run, so parallel runs never collide on the same data. See [Datasets](/writing-tests/which-variable/datasets.md) and [Lockable pools](/writing-tests/which-variable/lockable-pools.md).
* **Physical iOS device support.** Tests run on a real iPhone or iPad connected to your Mac, in addition to the simulator. Requires Developer Mode on the device and a signing team. Test plans require a real-device build. See [iOS physical device](/desktop-app/ios-physical-device.md).
* **Accessibility checks in reports.** Runs surface accessibility observations alongside the standard report. Visual checks only — no WCAG conformance scanning, screen reader testing, contrast analysis or ARIA validation. See [Known limitations](/reference/known-limitations.md#accessibility).
* **Private devices.** Devices reserved for a single organization, alongside local and cloud devices. Ask your Drizz contact about availability. See [Devices](/running-tests/devices.md).

* [Glossary](/reference/glossary.md) — terms used in these entries
* [Command index](/writing-tests/command-index.md) — every command, one table
