v1.19.1

Compare Source

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

We reverted the CRD-based API defaults forCertificate.Spec.IssuerRef andCertificateRequest.Spec.IssuerRef after they were found to cause unexpected certificate renewals after upgrading to 1.19.0. We will try re-introducing these API defaults in cert-manager1.20.
We fixed a bug that caused certificates to be re-issued unexpectedly if theissuerRef kind or group was changed to one of the "runtime" default values.
We upgraded Go to1.25.3 to address the following security vulnerabilities:CVE-2025-61724,CVE-2025-58187,CVE-2025-47912,CVE-2025-58183,CVE-2025-61723,CVE-2025-58186,CVE-2025-58185,CVE-2025-58188, andCVE-2025-61725.

cert-manager is the easiest way to automatically manage certificates in Kubernetes and OpenShift clusters.

We fixed a bug which caused certificates to be re-issued unexpectedly, if the issuerRef kind or group was changed to one of the "runtime" default values. We increased the size limit when parsing PEM certificate chains to handle leaf certificates with large numbers of DNS named or other identities. We upgraded Go to 1.24.9 to fix various non-critical security vulnerabilities.

This change fixes the following issue:#​7791

v1.11.1

Compare Source

This release fixes#​1785 introduced in v1.11.0 where expected argument values implementing the stringer interface (String() string) with a method which mutates their value, when passed to mock.Mock.On (m.On("Method", <expected>).Return()) or actual argument values passed to mock.Mock.Called may no longer match one another where they previously did match. The behaviour prior to v1.11.0 where the stringer is always called is restored. Future testify releases may not call the stringer method at all in this case.

What's Changed

• Backport#​1786 to release/1.11: mock: revert to pre-v1.11.0 argument matching behavior for mutating stringers by@​brackendawson in#​1788
