This is an update release of WPILib for the 2023 season. This release reduces overhead that can impact loop times in Java, and has several other quality-of-life improvements. Note: while this release only has a few changes since 2023.4.2, it includes all fixes made in earlier releases; it's strongly recommended teams upgrade if running versions earlier than 2023.4.1.
Upgrading from earlier 2023 releases is easy: simply download and run the new installer and it will update your current installation. If you already have the 2023 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.
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.
Minimum system requirements have changed for 2023. WPILib requires 64-bit Windows 10 or 11, Ubuntu 22.04, or macOS 11 or higher. Newly supported this year is Apple Silicon (arm64)! C++ teams should note that Visual Studio 2022 is now required for desktop builds. For this release, Mac users will need to have the Xcode Command Line Tools installed before running the installer; we are working on removing this requirement in a future release. 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 2023; be sure to read through this, as a lot has changed from 2022! You will need a new RoboRIO image for 2023; this is available via the FRC 2023 Game Tools. Follow the WPILib installation guide to install WPILib.
If you're starting from a 2022 robot project, you will need to import your project to create a 2023 project. The import process is important, as it will make a number of automated corrections for some breaking changes that happened in 2023. 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.
A complete list of known issues with this release can be found here.
WPILib is developed by a small team of volunteers and the FIRST community.
