      Limitations of the Flatpak version:
      
        C#/.NET external editor support does not work out-of-the-box, though this is currently being discussed and worked on. See: https://github.com/flathub/org.godotengine.GodotSharp/issues/2
        External script editors are still supported (for use outside of C#/.NET), but you need to follow the steps described here: https://github.com/flathub/org.godotengine.GodotSharp#using-an-external-script-editor
        After the first C# script is created, it is necessary to click Build within Godot. Alternatively, running dotnet restore in the IDE's terminal would work as well.
        Godot 4's Blender importer is supported, but Blender needs to be installed on your system and you need to follow the steps described here: https://github.com/flathub/org.godotengine.GodotSharp#using-blender

STM32CubeIDE is an advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors. It is based on the ECLIPSE™/CDT framework and GCC toolchain for the development, and GDB for the debugging. It allows the integration of the hundreds of existing plugins that complete the features of the ECLIPSE™ IDE.STM32CubeIDE integrates all STM32CubeMX functionalities to offer all-in-one tool experience and save installation and development time. After the selection of an empty STM32 MCU or MPU, or preconfigured microcontroller or microprocessor from the selection of a board, the project is created and initialization code generated. At any time during the development, the user can return to the initialization and configuration of the peripherals or middleware and regenerate the initialization code with no impact on the user code.STM32CubeIDE includes build and stack analyzers that provide the user with useful information about project status and memory requirements.STM32CubeIDE also includes standard and advanced debugging features including views of CPU core registers, memories, and peripheral registers, as well as live variable watch, Serial Wire Viewer interface, or fault analyzer.Note: For flashing to work properly you will need to add udev rules according to your device. If your device has an id of 0483:374b (check lsusb), you will need to create a file in /etc/udev/rules.d/ with the contents: SUBSYSTEMS=="usb", ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", GROUP="users", MODE="0666" and either reboot or run: sudo udevadm control --reload
