The biggest change in 4.3 is that surface support is now delivered through a downloadable module system β the same approach already used for connections.
Previously, support for every surface was baked into Companion itself, meaning you needed a full Companion update to get support for a new Stream Deck model or a surface bug fix.
This means:
We hope this will encourage others to add support for new types of surfaces. The development experience is similar to that of connection modules.
Surfaces can now be individually enabled or disabled from the Surfaces page. Disabling a surface stops Companion from claiming it, but preserves its configuration for when you want to re-enable it.
This is useful when running Companion alongside other software (such as the Elgato Stream Deck app) β you can pick which devices each application manages.
The connection module API has had a major revision in this release. The main change is to make it possible for any action or feedback input field to support expressions. Where supported, a toggle button next to the input field lets you switch it into expression mode.
Unfortunately, this requires modules to update to the latest version of the module-api making this opt in. We hope to see many modules start to support this in the coming months β it greatly increases the flexibility of Companion.
The Elgato Stream Deck plugin has been updated to support connecting over the Satellite API making it the preferred way for the plugin to connect to Companion.
Previously, the plugin communicated with Companion using an older, Elgato plugin-specific protocol. The Satellite API is a more modern, general-purpose alternative that is already used by the Satellite application and other third party software and hardware. Using it for the plugin means consistent behaviour across all surface types and a simpler integration overall.
If you are currently using the Elgato plugin, you can continue using it as before; however, we intend to remove support for the old protocol in a couple of Companion releases' time. When setting up a new connection, the plugin will now guide you toward using the Satellite API instead.
The plugin has also received a number of UI bug fixes.

This is a slightly smaller release than usual, focussing more on smaller improvements.
This version of Companion requires macOS 12 or later
The Companion User Guide has been rewritten to use a new rendering system.
This allows us to host a new publicly available version of the documentation online which is versioned per release, as well as building it in a simplified form within Companion
The new tools allow us to do more with the documentation and will make it easier for us to keep up to date too!
The expression editor input field has been rebuilt, making it easier to use with functionality you would expect from a code editor. This includes functions and keyword suggestions, and better handling of multi-line expressions.
