| Embarcadero Confidential/NDA 1.1 Known Issues In This Beta Build ● The new Welcome Page is present, but not fully complete: ○ Information loaded from GetIt will not display, and it will show a spinning wheel only. ○ Similarly the buttons at the top do not work. ○ The fonts or general look and feel used in the lists are not final ○ The custom layout are not persistent if you restart RAD Studio ● New IDE icons are not final. Some have errors in the dark theme, and some others will be redesigned or replaced. ● Debugging macOS ARM apps may require some Python configuration. See the documentation below how to do this. ● Warning: Android applications use a new set of Java libraries. When you are creating a new project, it will have the correct references. When you are upgrading an Android project created with a previous version of RAD Studio, you need to update the Java libraries references manually, with these steps. See the section Android 30 API Support. 2 Beta Installation and General Information The “Olympus” Beta can coexist with any previous version installation (like 10.4.x or 10.3.x) on the same machine or VM, but we recommend installing Beta versions on a separate machine or VM rather than on your primary development machine. Hardware and operating system requirements for installing and running “Olympus” are the same as 10.4 Sydney, listed here. Copyright © 2021 Embarcadero Technologies, Inc. | Embarcadero Confidential/NDA 2.1 Supported Target Platforms RAD Studio “Olympus” is expected to support the following target platforms: Supported Supported UI Languages Frameworks OS Supported Versions Target Platform Delphi C++ FireMonkey VCL Windows 32-bit ✔ ✔ ✔ ✔ Windows 10, Windows 7 Windows (SP1+), Windows Server 2019 and 2016 Windows 64-bit ✔ ✔ ✔ ✔ macOS Intel 64-bit ✔ ✔ macOS 11 Big Sur, 10.15 Catalina macOS ARM 64-bit ✔ ✔ iOS iOS14 iOS Device 64-bit ✔ ✔ ✔ Android 32-bit ✔ ✔ ✔ Android 11, 10, 9, 8.1 Android 64-bit ✔ ✔ Ubuntu 20.04 LTS and 18.04 LTS, RedHat Enterprise Linux Linux Intel 64-bit ✔ ✔1 Linux v8, WSL2 (Windows Subsystem for Linux) 2.2 Third Party Beta components Third party components for previous versions of RAD Studio are generally not compatible with the “Olympus” Beta. You can use the Quality Portal RSB issue for sharing binaries or download links with other beta testers. 1 Via FMX Linux, now available from Embarcadero as part of RAD Studio. Copyright © 2021 Embarcadero Technologies, Inc. | Embarcadero Confidential/NDA 2.3 How to log Beta bugs To log bugs found in the Beta, login to Embarcadero’s Quality Portal using your Embarcadero Developer Network (EDN) credentials. Attention: Use your username to log in to EDN. Email address is not supported. If you are having trouble logging in, please contact [email protected]. Same if RAD Studio Beta is not in the Project dropdown list. Click Create issue on the top bar and select RAD Studio Beta from the Project list: Before logging a bug, please verify that the bug does not already exist in the system. Duplicate bug reports waste time for both the person logging the bug and the evaluator, who has to reproduce it to determine if it is similar to other bugs.
