> ⚠️ This version has known issues. Please install `v1.14.1` instead.
>
> During the release of `v1.14.0`, the Helm chart was found to use the wrong OCI image for the `cainjector` Deployment,
> which caused the Helm installation and the static manifest based installation to fail.
> Upon discovery of this bug, the release of `v1.14.0` was paused before the Helm chart or GitHub release were published;
> but the Git tag and the OCI images had already been published.
>
> The cert-manager team next fixed the Helm chart and two other bugs which are listed in the "Known Issues" section below,
> and then released `v1.14.1`, which is the version that users are strongly advised to install when they upgrade to 1.14.
>
> In order to complete the stalled `v1.14.0` release,
> the Helm chart and static YAML installation files were regenerated on a team member's laptop,
> using exactly the same build scripts as are used in the automated release process,
> and using the `v1.14.1` version of the code.
> The working `v1.14.0` Helm chart was published,
> and the working versions of the static manifest files attached to the draft `v1.14.0` GitHub release,
> and that was then published.
>
> For these reasons, users are strongly advised to skip this version and install the `v1.14.1` Helm chart instead.
##### Known Issues
- During the release of `v1.14.0`, the Helm chart for this version was found to use the wrong OCI image for the `cainjector` Deployment,
which caused the Helm installation to fail.
In order to complete the release, the cert-manager team have manually updated the Helm chart for this version,
which contains all the Helm chart fixes which are in `v1.14.1`.
But users are strongly advised to skip this version and install the `v1.14.1` Helm chart instead.
- A bug in cmctl namespace detection prevents it being used as a `startupapicheck` image in namespaces other than cert-manager.
- A bug in cmctl causes `cmctl experimental install` to panic.
##### Breaking Changes
The startupapicheck job uses a new OCI image called "startupapicheck", instead of the ctl image.
If you run in an environment in which images cannot be pulled, be sure to include the new image.
The KeyUsage and BasicConstraints extensions will now be encoded as critical in the CertificateRequest's CSR blob.
##### Major Themes
##### New X.509 Features
The cert-manager Certificate resource now allows you to configure a subset of "Other Name" SANs,
which are described in the [Subject Alternative Name section of RFC 5280](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.6) (on page 37).
We specifically support any `otherName` type with a `UTF-8` value, such as the [User Principal Name](https://docs.venafi.com/Docs/current/TopNav/Content/Certificates/r-UEP-support-SANs.php) or [`sAMAccountName`](https://learn.microsoft.com/en-us/windows/win32/ad/naming-properties).
These are useful when issuing unique certificates for authenticating with LDAP systems such as Microsoft Active Directory.
For example you can create certificates with this block in the spec:
otherNames:
- oid: 1.3.6.1.4.1.311.20.2.3 # UPN OID
utf8Value: upn@domain.local
The feature is still in alpha stage and requires you to [enable the `OtherName` feature flag in the controller and webhook components](../../installation/configuring-components.md#feature-gates).
##### New CA certificate Features
You can now specify the X.509 v3 Authority Information Accessors extension,
with URLs for certificates issued by the CA issuer.
Users can now use name constraints in CA certificates.
To know more details on name constraints check out RFC section https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.10
##### Security
An ongoing security audit of the cert-manager code revealed some weaknesses which we have addressed in this release,
such as using more secure default settings in the HTTP servers that serve metrics, healthz and pprof endpoints.
This will help mitigate denial-of-service attacks against those important services.
All the cert-manager containers are now configured with read only root file system by default,
to prevent unexpected changes to the file system of the OCI image.
And it is now possible to configure the metrics server to use HTTPS rather than HTTP,
so that clients can verify the identity of the metrics server.
##### Other
The liveness probe of the cert-manager controller Pod is now enabled by default.
There is a new option `.spec.keystores.pkcs12.algorithms` to specify encryption and MAC algorithms for PKCS.

##### Changes
##### Feature
- ACME challenge solver Pod for HTTP01 will get a default annotation of `"cluster-autoscaler.kubernetes.io/safe-to-evict": "true"`. You can provide an annotation of `"cluster-autoscaler.kubernetes.io/safe-to-evict": "false"` in your `podTemplate` if you don't like this. ([#6349](https://togithub.com/cert-manager/cert-manager/pull/6349), [@jsoref](https://togithub.com/jsoref))
- Added a clock skew detector liveness probe that will force a restart in case we detect a skew between the internal monotonic clock and the system clock of more than 5 minutes.
Also, the controller's liveness probe is now enabled by default. ([#6328](https://togithub.com/cert-manager/cert-manager/pull/6328), [@inteon](https://togithub.com/inteon))

- Users can now use name constraints in CA certificates. To know more details on name constraints check out RFC section https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.10 ([#6500](https://togithub.com/cert-manager/cert-manager/pull/6500), [@tanujd11](https://togithub.com/tanujd11))
- ⚠️ potentially breaking ⚠️: The KeyUsage and BasicConstraints extensions will now be encoded as critical in the CertificateRequest's CSR blob. ([#6053](https://togithub.com/cert-manager/cert-manager/pull/6053), [@inteon](https://togithub.com/inteon))
- Add TLS support to the metrics endpoint through either a certificate file or through dynamically issued certificates ([#6574](https://togithub.com/cert-manager/cert-manager/pull/6574), [@ThatsMrTalbot](https://togithub.com/ThatsMrTalbot))

- `GHSA-vgf6-pvf4-34rq`: The webhook server now returns HTTP error 413 (Content Too Large) for requests with body size `>= 3MiB`. This is to mitigate DoS attacks that attempt to crash the webhook process by sending large requests that exceed the available memory.
The webhook server now returns HTTP error 400 (Bad Request) if the request contains an empty body.
The webhook server now returns HTTP error 500 (Internal Server Error) rather than crashing, if the code panics while handling a request. ([#6498](https://togithub.com/cert-manager/cert-manager/pull/6498), [@inteon](https://togithub.com/inteon))
- Increase the default webhook timeout to its maximum value of 30 seconds, so that the underlying timeout error message has more chance of being returned to the end user. ([#6488](https://togithub.com/cert-manager/cert-manager/pull/6488), [@wallrj](https://togithub.com/wallrj))

- The Venafi issuer now properly resets the certificate and should no longer get stuck with `WebSDK CertRequest Module Requested Certificate` or `This certificate cannot be processed while it is in an error state. Fix any errors, and then click Retry.`. ([#6398](https://togithub.com/cert-manager/cert-manager/pull/6398), [@maelvls](https://togithub.com/maelvls))
- Update experimental install and uninstall commands to have flag parity with the rest of the CLI ([#6562](https://togithub.com/cert-manager/cert-manager/pull/6562), [@ThatsMrTalbot](https://togithub.com/ThatsMrTalbot))
- Webhook ConfigMap if now created only if `.Values.webhook.config` is set. ([#6360](https://togithub.com/cert-manager/cert-manager/pull/6360), [@ABWassim](https://togithub.com/ABWassim))
- BUGFIX: Ensure `otherName` SAN changes in Certificate resources trigger re-issuance. ([#6620](https://togithub.com/cert-manager/cert-manager/pull/6620), [@SpectralHiss](https://togithub.com/SpectralHiss))

The KeyUsage and BasicConstraints extensions will now be encoded as critical in the CertificateRequest's CSR blob. ##### Major Themes ##### New X.509 Features The cert-manager Certificate resource now allows you to configure a subset of "Other Name" SANs, which are described in the [Subject Alternative Name section of RFC 5280](https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.6) (on page 37). We specifically support any `otherName` type with a `UTF-8` value, such as the [User Principal Name](https://docs.venafi.com/Docs/current/TopNav/Content/Certificates/r-UEP-support-SANs.php) or [`sAMAccountName`](https://learn.microsoft.com/en-us/windows/win32/ad/naming-properties). These are useful when issuing unique certificates for authenticating with LDAP systems such as Microsoft Active Directory. For example you can create certificates with this block in the spec: otherNames: - oid: 1.3.6.1.4.1.311.20.2.3 # UPN OID utf8Value: upn@domain.local The feature is still in alpha stage and requires you to [enable the `OtherName` feature flag in the controller and webhook components](../../installation/configuring-components.md#feature-gates). ##### New CA certificate Features You can now specify the X.509 v3 Authority Information Accessors extension, with URLs for certificates issued by the CA issuer. Users can now use name constraints in CA certificates. To know more details on name constraints check out RFC section https://datatracker.ietf.org/doc/html/rfc5280#section-4.2.1.10 ##### Security An ongoing security audit of the cert-manager code revealed some weaknesses which we have addressed in this release, such as using more secure default settings in the HTTP servers that serve metrics, healthz and pprof endpoints. This will help mitigate denial-of-service attacks against those important services. All the cert-manager containers are now configured with read only root file system by default, to prevent unexpected changes to the file system of the OCI image. And it is now possible to configure the metrics server to use HTTPS rather than HTTP, so that clients can verify the identity of the metrics server. ##### Other The liveness probe of the cert-manager controller Pod is now enabled by default. There is a new option `.spec.keystores.pkcs12.algorithms` to specify encryption and MAC algorithms for PKCS. ##### Community Thanks again to all open-source contributors with commits in this release, including: - [@ABWassim](https://togithub.com/ABWassim) - [@JoeNorth](https://togithub.com/JoeNorth) - [@allenmunC1](https://togithub.com/allenmunC1) - [@asapekia](https://togithub.com/asapekia) - [@jeremycampbell](https://togithub.com/jeremycampbell) - [@jkroepke](https://togithub.com/jkroepke) - [@jsoref](https://togithub.com/jsoref) - [@lauraseidler](https://togithub.com/lauraseidler) - [@pevidex](https://togithub.com/pevidex) - [@phillebaba](https://togithub.com/phillebaba) - [@snorwin](https://togithub.com/snorwin) - [@tanujd11](https://togithub.com/tanujd11) - [@tberreis](https://togithub.com/tberreis) - [@vinny](https://togithub.com/vinny) Thanks also to the following cert-manager maintainers for their contributions during this release: - [@SgtCoDFish](https://togithub.com/SgtCoDFish) - [@SpectralHiss](https://togithub.com/SpectralHiss) - [@ThatsMrTalbot](https://togithub.com/ThatsMrTalbot) - [@hawksight](https://togithub.com/hawksight) - [@inteon](https://togithub.com/inteon) - [@maelvls](https://togithub.com/maelvls) - [@wallrj](https://togithub.com/wallrj) Equally thanks to everyone who provided feedback, helped users and raised issues on GitHub and Slack and joined our meetings!
