# What's new
 | 
			
		||||
 | 
			
		||||
- Updated to the node16 runtime by default
 | 
			
		||||
  - This requires a minimum [Actions Runner](https://github.com/actions/runner/releases/tag/v2.285.0) version of v2.285.0 to run, which is by default available in GHES 3.4 or later.
 | 
			
		||||
- Updated default runtime to node20
 | 
			
		||||
  - This requires a minimum Actions Runner version of [v2.308.0](https://github.com/actions/runner/releases/tag/v2.308.0).
 | 
			
		||||
- Added support for fetching without the `--progress` option
