1. Castle Model Viewer for Android version 2.8 has been released! This brings:
   • Support for IFC format right in our mobile viewer.

   • Small UI improvements: better button order (left-most changes model), show more built-in files.

   • Opening ZIP files underneath doesn’t create temp directory on your device. Internally, this is achieved by using TCastleZip to open ZIP files. The TCastleZip class also makes code simpler, and compatible with both FPC and Delphi.

   • Fix: No more crashes on Android 15 (on some devices, like Google Pixel 6a, argv is broken after Android upgrade).

   • Fix: Take into account safe borders on left/right.

   • And all improvements and optimizations from the Castle Game Engine done recently. Including target Android version bump, mentioned below.

2. All other Castle Game Engine applications on Google Play have been upgraded as well, to include all the latest improvements from the engine, including the target Android version bump.

3. On the engine side, we have migrated google_play_games service to use version 2 of the Google API. New applications uploaded to Google Play are required to use this version.

   Please note that v2 is somewhat less functional than v1. E.g. there’s no way to explicitly request sign-out. It’s just how Google made it, and we have to adjust, see migrating to Play Games Services v2 about all changes.

4. We also bump the “target” Android version to 35, as required by Google Play. This will be required by Google Play since 31 August 2025, see Target API level requirements for Google Play apps. Nothing in practice changes for you because of this (it doesn’t affect minimal version supported).
