The configurations below represent the current build targets for the API, samples, and applications in this release. Many similar configurations are known to work (e.g. Linux Ubuntu, etc) but these are the official distribution targets. 

Language columns (C/C++, Python, Java, Ruby, C#): These indicate availability of FrontPanel API language bindings — wrapper libraries that allow applications written in those languages to call FrontPanel API functions directly.

Platform column: “Yes” indicates that the FrontPanel Platform application is available for that operating system. FrontPanel Platform is an Electron-based application that includes the graphical Device Manager and hosts TypeScript/JavaScript GUI applications such as the bundled examples and any custom apps you develop.

• Ubuntu 20.04 LTS support has been removed from FrontPanel 6+ went end-of-life 2025-04-30.

• The FrontPanel Platform is now the supported application for managing FrontPanel-based devices.
• FrontPanel Platform Example application sources added for Counters, DES, PipeTest, and RAMTester
• Wire, Trigger, and Pipe Methods have been moved into a new FPGADataPortClassic class.
• New GetFPGADataPortClassic and GetFPGADataPortAXI methods have been added to FrontPanel class.
• Example source have been updated to use the new FPGADataPortClassic class.
• FrontPanel::Error code has been replaced with OpalKelly::ErrorCode

The following deprecated methods have been removed in FrontPanel 6.0.
