Arduino IDE offers an update to the user when a newer version is available. The availability of an update is determined
by comparing the user's IDE version against data file ("channel update info file") stored on Arduino's download server.
These "channel update info files" are automatically generated by the build workflow.
Previously the release process was fully automated, including the upload of the "channel update info files" to the
server.
As a temporary workaround for limitations of the GitHub Actions runner machines used to produce the automated builds,
some release builds are now produced manually:
- Linux build (because the Ubuntu 18.04 runner was shut down and newer runner versions produce builds incompatible with
older Linux versions)
- macOS Apple Silicon build (because GitHub hosted Apple Silicon runners are not available)
The automatic upload of the "channel update info files" produced by the build workflow is problematic because if users
receive update offers before the "channel update info files" are updated for the manually produced builds, they can
receive an update to a different build than intended:
- Users of older Linux versions would update to a build that won't start on their machine
- macOS Apple Silicon users would update to macOS x86 build that is less performant on their machine
For this reason, the build workflow is adjusted to no longer upload the Linux and macOS "channel update info files" to
the download server on release. These files will now be manually uploaded after they have been updated to provide the
manually produced builds.
This workaround will be reverted once a fully automated release system is regained.
Arduino IDE 2.x
This repository contains the source code of the Arduino IDE 2.x. If you're looking for the old IDE, go to the repository of the 1.x version at https://github.com/arduino/Arduino.
The Arduino IDE 2.x is a major rewrite, sharing no code with the IDE 1.x. It is based on the Theia IDE framework and built with Electron. The backend operations such as compilation and uploading are offloaded to an arduino-cli instance running in daemon mode. This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade.
