Understanding Versioning Requirements

When updating to a new version of our Desktop certain previous versions are required to be installed. Here’s how it works:

  • Minor Updates (e.g., 20.0.1): - You need the base version (e.g., 20.0.0) installed.
  • Feature Updates (e.g., 20.1.0): - You need the base version (e.g., 20.0.0) installed.
  • Patch Updates (e.g., 20.1.2): - You need the base version (e.g., 20.0.0) and the most recent feature update (e.g., 20.1.0) installed.

If the necessary versions are already installed, no need to download them again.
