## REST Operations Resource Support

Added REST operations to the resources DSL. ([#12755](https://github.com/chef/chef/pull/12755))

This allows you to create a resource partial that can be used in a custom resource like this:

```rb
use "core::rest_resource"

provides :rest_resource_by_query, target_mode: true

property :address, String, required: true
property :prefix, Integer, required: true
property :gateway, String

rest_api_collection "/api/v1/addresses"
rest_api_document   "/api/v1/address/?ip={address}"
rest_property_map({
  address: "address",
  prefix: "prefix",
  gateway: "gateway",
})
```

Thanks to the folks at [tecRacer 1](https://chef.tecracer.de/) for providing the foundation for this feature.

## Unified Mode in Custom Resources

[Unified mode](https://docs.chef.io/unified_mode/) is now enabled for custom resources by default. ([#12692](https://github.com/chef/chef/pull/12692))

In Chef Infra Client 16, we introduced unified mode allowing you to collapse the sometimes confusing compile and converge phases into a single unified phase. Unified mode makes it easier to write and troubleshoot failures in custom resources and this is now the default execution phase for custom resources. Set unified_mode false in a custom resource if you need to disable unified mode.

### Potential Breaking Change

If your custom resources have specific compile/converge phase behaviors, please test them for compatibility. For more information, see the [Out-of-Order Execution](https://docs.chef.io/unified_mode/#out-of-order-execution) section of the Unified Mode documentation.

## Known Issues

### FIPS support on Windows

Shortly before the final GA build of Chef Infra Client 18, we discovered an issue with FIPS support for Windows. We are currently investigating the root cause and correcting the issue; however, please note that FIPS support will not be available in the initial GA version of Chef Infra Client 18.0 for all Windows versions. We have prioritized this issue and FIPS support will be released in the next minor version of Chef Infra Client (18.1). We are reviewing the release date for Chef Infra Client 18.1 with FIPS support and will announce that date on all major communication channels when it is established.

### Support for Effortless on Windows

Chef Infra Client 18.0.169 does not include support for effortless on Windows.

## Resource Updates

### chef_client_config

The `:create` action will now create directories defined in the resource properties if they are defined but don't exist. ([#12416](https://github.com/chef/chef/pull/12416))

Added a rubygems_url property that allows users to specify URI as a source for Ruby gems. This could be an internal mirror of rubygems for airgapped environments. ([#12724](https://github.com/chef/chef/pull/12724)) Thanks ([DecoyJoe](https://github.com/DecoyJoe))!

### chef_client_launchd

The chef_client_launchd resource now runs at load instead instead of requiring a system restart before running. ([#12706](https://github.com/chef/chef/pull/12706))

### rhsm_register

The rhsm_register resource now flushes the internal package cache after registering with Red Hat Satellite. ([#12828](https://github.com/chef/chef/pull/12828)) Thanks for fixing this [@jasonwbarnett](https://discourse.chef.io/u/jasonwbarnett)!

### user

The user resource now has expire_date and inactive properties on Linux systems that specify the date a user account will be disabled and the number days after a password expires before an account is permanently disabled.

## Secrets Manager Integration

The [Secrets Management Integration helper](https://docs.chef.io/infra_language/secrets/) is now a fully supported feature. The Secrets Management Integration helper allows you to fetch secrets from the following secrets management systems within your Infra recipes or resources:

* AWS Secrets Manager
* Akeyless Vault
* Azure Key Vault
* HashiCorp Vault

## Platform Support Updates

### AIX 7.3

Chef Infra Client packages are now produced for AIX 7.3.

### AlmaLinux 8

Chef Infra Client packages are now produced for AlmaLinux 8.

### Amazon 2022

Chef Infra Client packages are now produced for Amazon Linux 2022.

### CentOS 8

CentOS 8 became end-of-life on December 2021. Chef Infra Client packages are no longer produced for CentOS 8, which is being replaced by AlmaLinux 8.

### Windows 8

Chef Infra Client packages are no longer produced for Windows 8.

### 32-bit Windows

Chef Infra Client packages are no longer produced for 32-bit versions of Windows.

## Security

### Sensitive Properties in Custom Resources

Fixed an issue in custom resources where Chef Infra Client was logging data of properties with sensitive: true and desired_state: false. ([#13014](https://github.com/chef/chef/pull/13014))

### Migrate PEM Storage to Certificate Store for Windows

Use migrate_key_to_keystore true in the Chef Infra Client config.rb to migrate certificates to the Windows certificate store on Windows nodes.
This creates a PFX certificate, extracts a public key from the certificate and sends it to the Chef Infra Server, and then stores the certificate in the local certificate store.

Certificates have a 90-day lifespan. If a certificate is expiring, Infra Client will automatically generate a new one and store it in the local certificate store, and then generate and replace the older public key on the Infra Server. ([#12910](https://github.com/chef/chef/pull/12910)) ([#12640](https://github.com/chef/chef/pull/12640)) ([#12426](https://github.com/chef/chef/pull/12426)) ([#12518](https://github.com/chef/chef/pull/12518))
