v1.18.1

This release fixes a memory leak introduced in OPA v1.17.0. It is advised to update if you notice excess memory usage when running OPA server.

Fixes

• ast: fix AnnotationSet memory leak via runtime.AddCleanup cycle (#8817) authored by @​srenatus reported by @​keydon and @​gorsr01

v1.18.0

This release contains a mix of bugfixes and small features. Notably:

• A breaking fix to the outbound User-Agent header so it conforms to RFC 9110 (see below)
• Container-aware resource limits: automatic GOMAXPROCS is restored and automatic GOMEMLIMIT is now supported
• Several opa fmt correctness fixes
• Improvements to opa test --coverage (ranges in report, inline rule head tracking, conjunction-expression coverage)

Breaking: Fix User-Agent according to RFC9110 (#8792)

OPA's outbound HTTP requests (bundle, discovery, decision log, status, http.send, AWS KMS/ECR) previously sent User-Agent: Open Policy Agent/<version> (<os>, <arch>), which is not a valid RFC 9110 User-Agent value because the product token cannot contain spaces. The header is now Open-Policy-Agent/<version> (<os>, <arch>). Server-side log filters or WAF rules that exact-match the old string will need to be updated.
