The ability to make the Redis installation optional in the Sentinel setup (useful when you manage Redis installation in separate manifests/modules)
The ability to specify the bind parameter in the Sentinel config
Executes the Sentinel config file copy as root instead of redis. This caused subsequent Puppet runs to break since the redis user didn't have write privs on /etc/redis (this is advisable for security). Since we already specify the file should be owner => redis, group => redis specifying it again is unnecessary
