v0.47.4

This is a bug fix release addressing a panic in opa test.

• tester/runner: Fix panic'ing case in utility function. (#5496)

v0.47.3

This is a bug fix release addressing an issue that prevented OPA from fetching bundles stored in S3 buckets.

• providers/aws: Refactor + fix 2x Authorization header append issue. (#5472)

v0.47.2

This is a second security fix to address CVE-2022-41717/GO-2022-1144.

We previously believed that upgrading the Golang version and its stdlib would be sufficient to address the problem. It turns out we also need to bump the x/net dependency to v0.4.0., a version that hadn't existed when v0.46.2 was released.

This release bumps the golang.org/x/net dependency to v0.4.0, and contains no other changes over v0.46.2.

Note that the affected code is OPA's HTTP server. So if you're using OPA as a Golang library, or if your confident that your OPA's HTTP interface is protected by other means (as it should be -- not exposed to the public internet), you're OK.

v0.47.1

This is a bug fix release addressing two issues: one security issue, and one bug related to formatting backwards-compatibility.

Golang security fix CVE-2022-41717

An attacker can cause excessive memory growth in a Go server accepting HTTP/2 requests.

Since we advise against running an OPA service exposed to the general public of the internet, potential attackers would be limited to people that are already capable of sending direct requests to the OPA service.

opa fmt and backwards compatibility (#5449)

In v0.46.1, it was possible that opa fmt would format a rule in such a way that:

1. Before formatting, it was working fine with older OPA versions, and
2. after formatting, it would only work with OPA version >= 0.46.1.

This backwards incompatibility wasn't intended, and has now been fixed.

v0.47.0

This release contains a mix of bugfixes, optimizations, and new features.

New Built-in Function: object.keys
