Technology Updates
Functional Changes
HOOPS Server on Windows Server
A breaking change affects the Node.js spawner server on Windows due to the update of the embedded Node.js version (see below) where unmaintained third-party components were removed.
Wrappers like PM2 continue to function normally.
A custom JavaScript script is provided as an alternative for users not using wrappers.
