We are updating the Linux and Windows development snapshot signing key to 'Swift Automatic Signing Key #4', because 'Swift Automatic Signing Key #3' will expire.
Starting Nov 8th 2021 (tonight) we will be publishing development snapshots with the new signing key.
The new signing key is also available on https://swift.org/download under "Active Signing Keys”.
