This is an update release of WPILib for the 2024 season. This release improves dashboard NetworkTables connection/disconnection behavior and improves SysId, along with other bugfixes. This upgrade is recommended for all teams.
Upgrading from earlier 2024 releases is easy: simply download and run the new installer and it will update your current installation. If you already have the 2024 WPILib vscode installed, it will detect it and you can simply click "next" for that installation step. After installation, vscode will prompt you when opening your robot project whether you want to upgrade it to this version. Note that using the installer is required to get the new version of desktop tools such as Shuffleboard. This release is compatible with the kickoff release of the RoboRIO image, so there is no need to upgrade the RIO image if you have already done so for 2024. Mac note: for this release, it is necessary to manually remove the 2024.1.1 version of AdvantageScope before running the installer in order for the new version to be installed.
The documentation for WPILib is located at https://docs.wpilib.org/ (if you have trouble accessing this location, https://frcdocs.wpi.edu/en/stable/ is an alternate location with the same content).
If you're new to FRC, start with Getting Started.
System Requirements: WPILib requires 64-bit Windows 10 or 11, Ubuntu 22.04, or macOS 12 or higher. C++ teams should note that Visual Studio 2022 is required for desktop builds. Mac users will need to have the Xcode Command Line Tools installed before running the installer. This can be done by running xcode-select --install in the Terminal.
If you're returning from a previous season, check out what's new for 2024. You will need a new RoboRIO image for 2024; this is available via the FRC 2024 Game Tools. Follow the WPILib installation guide to install WPILib.
If you're starting from a 2023 robot project, you will need to import your project to create a 2024 project. The import process is important, as it will make a few automated corrections for some breaking changes that happened in 2024. It is also necessary to import vendor libraries again, since last year’s vendor libraries must be updated to be compatible with this year’s projects.

WPILib is developed by a small team of volunteers and the FIRST community.
