With this latest release, a number of improvements were introduced to improve the experience working with the CLI

• All the Javascript files and Node itself is packaged into a single executable (~/bin/particle on Mac/Linux and C:\Users\<user>\AppData\Local\particle\bin\particle.exe on Windows) so it downloads and updates a lot more quickly.
• The Windows installer now works completely offline.
• The CLI now works natively on Mac ARM and Raspberry Pi 2+.
• Workbench also uses this packaged CLI so initial installation of the CLI inside Workbench is much faster.

If you already have the CLI installed using the CLI installer, it will automatically update. If you need to install the CLI, visit Command Line | Getting Started | Particle
