-## Unreleased
+## 0.59.0
+
+This release adds tooling to help prepare existing policies for the upcoming OPA 1.0 release.
+It also contains a mix of improvements, bugfixes and security fixes for third-party libraries.
+
+> **_NOTES:_**
+>
+> * All published OPA images now run with a non-root uid/gid. The `uid:gid` is set to `1000:1000` for all images. As a result
+    there is no longer a need for the `-rootless` image variant and hence it will not be published as part of future releases.
+    This change is in line with container security best practices. OPA can still be run with root privileges by explicitly setting the user,
+    either with the `--user` argument for `docker run`, or by specifying the `securityContext` in the Kubernetes Pod specification.
+
+### Rego v1
+
+The upcoming release of OPA 1.0, which will be released at a future date, will introduce breaking changes to the Rego language. Most notably:
+
+* the keywords that currently must be imported through `import future.keywords` into a module before use will be part of the Rego language by default, without the need to first import them.
+* the `if` keyword will be required before the body of a rule.
+* the `contains` keyword will be required when declaring a multi-value rule (partial set rule).
+* deprecated built-in functions will be removed.
+
+This current release (`0.59.0`) introduces a new `--rego-v1` flag to the `opa fmt` and `opa check` commands to facilitate the transition of existing policies to be compatible with the 1.0 syntax.
+
+When used with `opa fmt`, the `--rego-v1` flag will format the module(s) according to the new Rego syntax in OPA 1.0. 
+Formatted modules are compatible with both the current version of OPA and 1.0. 
+Modules using deprecated built-ins will terminate formatting with an error. Future versions of OPA will support rewriting applicable function calls with equivalent Rego compatible with 1.0. 
+
+When used with `opa check`, the `--rego-v1` flag will check that the modules are compatible with both the current version of OPA and 1.0.
