• Additional exit codes 10 and 11 for when repository does not exist or cannot be locked.
• Support for reading the backup source from a command’s standard output.
• Support for backing up to rest-server over a unix socket.
• Support for AWS Assume Role with the S3 backend using the RESTIC_AWS_ASSUME_* environment variables.
