Device OS 3.0.0 Release is available in the Web IDE, Particle CLI and Workbench for (Photon/P1/Electron/Argon/Boron/B SoM/B5 SoM/Tracker).

Released on April 8th, 2021

Note: This is a Release and may be used for production. Any known issues are likely slated for a future version, see GitHub issues.

This is the first release on non-LTS feature development branch (3.x). To learn more about our new LTS release line, read our blog post.
