Release Notes

0.5.3 (2026-11-12) Preview​

A major rework of Endpoint. The deployment story, the IDE integration, the libraries, and the project layout have all been rebuilt. Because the scope is so wide, this release is published as a preview: expect some features to be untested, incomplete, or still changing. That is intentional for this cycle. The goal is to get the new foundation in front of users and iterate quickly from your feedback, not to deliver a polished final build. Firmware and IDE extensions ship and move together, so the notes below are listed once for the whole release rather than split per component.

Changes​

  • USB debugging. No more SSH. Plug in the USB cable, pick your board from the list, and press F5.
  • Three languages, one set of APIs. .NET 11, Python 3.14, and C23 and C++23 with no toolchain to install.
  • pip install over the debugger. Install Python packages onto the board from VS Code, over USB, with no internet connection on the board.
  • Faster startup. A C# blink application goes from power on to running in less than three seconds.
  • Run at boot. Ctrl+F5 compiles in AOT mode and sets the application to run at boot.
  • Configuration. Display and network configuration has been reworked. Load, modify, and save configuration from your application, or edit the JSON directly. A FAT32 partition is exposed so you can edit that file by opening the SD card image (SD card only for now).
  • APIs. All APIs were reworked to match .NET conventions.
  • IDEs. VS Code is fully supported for all three languages. Visual Studio supports .NET.

Known issues​

  • Not every feature is fully tested. This is a preview, so expect rough edges, and please report issues on the forum.
  • New Python project pauses for a few seconds after creation. VS Code is doing some internal setup; it clears on its own.
