+## Supported Release 4.12.0
+###Summary
+
+This release provides several new functions, bugfixes, and some documentation updates.
+
+####Features
+- Adds `clamp`. This function keeps values within a specified range.
+- Adds `validate_x509_rsa_key_pair`. This function validates an x509 RSA certificate and key pair.
+- Adds `dig`. This function performs a deep lookup in nested hashes or arrays.
+- Extends the `base64` support to fit `rfc2045` and `rfc4648`.
+- Adds `is_ipv6_address` and `is_ipv4_address`. These functions validate the specified ipv4 or ipv6 addresses.
+- Adds `enclose_ipv6`. This function encloses IPv6 addresses in square brackets.
+- Adds `ensure_resources`. This function takes a list of resources and creates them if they don't exist.
+- Extends `suffix` to support applying a suffix to keys in a hash.
+
+####Bugfixes
+- Fixes `fqdn_rand_string` tests, since Puppet 4.4.0 and later have a higher `fqdn_rand` ceiling.
+- (MODULES-3152) Adds a check to `package_provider` to prevent failures if Gem is not installed.
