-## Unreleased
+## 0.68.0
 
-- allow OpenTelemetry resource attributes to be configured under distributed_tracing config
+This release contains a mix of features and bugfixes.
+
+### Breaking Changes
+
+#### `entrypoint` annotation implies `document` scope ([#6798](https://github.com/open-policy-agent/opa/issues/6798))
+
+The [entrypoint annotation's](https://www.openpolicyagent.org/docs/latest/policy-language/#entrypoint) scope requirement 
+has changed from `rule` to `document` ([https://github.com/open-policy-agent/opa/issues/6798](#6798)). 
+Furthermore, if no `scope` annotation is declared for a METADATA block preceding a rule, the presence of an `entrypoint` 
+annotation with a `true` value will assign the block a `document` scope, where the `rule` scope is otherwise the default.
+
+In practice, a rule entrypoint always point to the entire document and not a particular rule definition. The previous behavior was a bug, and one we've now addressed.

+- ast+parser: Add hint to future-proof imports ([6968](https://github.com/open-policy-agent/opa/pull/6968)) authored by @srenatus
+- topdown: Adding unification scope to virtual-cache key. Fixing issue where false positive cache hits can occur when unification "restricts" the scope of ref-head rule evaluation ([#6926](https://github.com/open-policy-agent/opa/issues/6926)) authored by @johanfylling reported by @anderseknert

+### Runtime, Tooling, SDK
 
-- `opa exec`: This command never supported "pretty" formatting (`--format=pretty` or `-f pretty`), only `json`. Passing `pretty` is now invalid.

+- plugins/rest: Support AWS_CONTAINER_CREDENTIALS_FULL_URI metadata endpoint ([#6893](https://github.com/open-policy-agent/opa/issues/6893)) authored and reported by @mbamber
+- util+server: Fix bug around chunked request handling. ([#6904](https://github.com/open-policy-agent/opa/issues/6904)) authored by @philipaconrad reported by @David-Wobrock
+- `opa exec`: This command never supported "pretty" formatting (`--format=pretty` or `-f pretty`), only `json`. Passing `pretty` is now invalid. ([#6923](https://github.com/open-policy-agent/opa/pull/6923)) authored by @srenatus
   Note that the flag is now unnecessary, but it's kept so existing calls like `opa exec -fjson ...` remain valid.
 
+#### Security Fix: CVE-2024-8260 ([#6933](https://github.com/open-policy-agent/opa/pull/6933))
+
+This release includes a fix where OPA would accept UNC locations on Windows. Reading those could leak NTLM hashes.
+The attack vector would include an adversary tricking the user in passing an UNC path to OPA, e.g. `opa eval -d $FILE`.
+UNC paths are now forbidden. If this is an issue for you, please reach out on Slack or GitHub issues.
