 # Changelog
 
+## Unreleased
+
+### Behavioral Changes
+
+- The device name (`device.name`), which often contains the user's name, is now only sent when `SendDefaultPii` is enabled. This also applies to native crashes on desktop and consoles. ([#2932](https://github.com/getsentry/sentry-unity/pull/2932))

 ## 4.12.0
