Breaking Changes

entrypoint annotation implies document scope (#​6798)

The entrypoint annotation's scope requirement
has changed from rule to document (https://github.com/open-policy-agent/opa/issues/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.

• opa exec: This command never supported "pretty" formatting (--format=pretty� or -f pretty), only json. Passing pretty is now invalid. (#​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)

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.
