# Release Note - Unreal SDK
## 2026
### v1.4.1 - Aug 12, 2026
**IMPORTANT**
* In v1.4.0, the PT\_GNU\_RELRO segment of the SDK's native libraries was not aligned to the 16 KB boundary. This does not affect app behavior on 16 KB page size devices, but Google Play Console may display a 16 KB page size warning when uploading your app. v1.4.1 resolves this alignment issue. If you are using v1.4.0, please update to v1.4.1 or later. See the troubleshooting guide for details.

### v4.9.0 - Jun 22, 2026
**IMPORTANT**
* Airbridge Unreal SDK has supported 16 KB page sizes since v4.6.0. However, in v4.6.0–v4.8.0, the PT\_GNU\_RELRO segment of the SDK's native libraries was not aligned to the 16 KB boundary. This does not affect app behavior on 16 KB page size devices, but Google Play Console may still display a 16 KB page size warning when uploading your app. v4.9.0 resolves this by upgrading the NDK version used to build the SDK. If you are using v4.6.0–v4.8.0, please update to v4.9.0 or later. See the troubleshooting guide for details.
