-<!-- API changelog requirements - delete this before merging -->- Replace all instances of X.X.X in the frontmatter with the appropriate API spec.- Replace all instances of 2019-01-01 with the production release date for the API.- All items in the changelog should mention which endpoints are affected.- For changes and bugfixes, describe the previous behavior AND the new behavior.
-<!-- Where to put things - delete this before merging -->Some heuristics for which heading to put API reference updates under:
-*Added*- New endpoints.- New fields in the request or a response of an existing endpoint.
-*Changed*- Changes in the behavior of an existing endpoing, when the previous behavior was working as it was designed. In other words, non-bugfix changes.
-*Fixes*- Bugfixes: Changes to the behavior of an endpoint, where the previous behavior was not working as intended/expected/documented.
-<!-- Sample syntax - delete this before merging -->
-- References to an endpoint should be in this format: `the Endpoint Name ([VERB /path/to/endpoint/{endpointVariable}](https://developers.linode.com/api/docs/v4/{endpoint}/{#endpointVariable})) endpoint` *Example*: `the Clone Linode ([POST /linode/instances/{linodeId}/clone](https://developers.linode.com/api/v4/linode-instances-linode-id-clone/#post)) endpoint`

 ### Added
+
+- You can now add tags when creating an LKE cluster ([POST /lke/clusters](/api/v4/lke-clusters/#post)). While the `tags` property existed before, the implementation logic has now been added to support adding tags to an LKE cluster.
+
+- A `tags` property was added to the Update Kubernetes Cluster ([PUT /lke/clusters/{clusterId}](/api/v4/lke-clusters-cluster-id/#put)) endpoint. You can now update or remove existing tags on your LKE clusters. The `tags` property accepts an array of tags to be applied to your LKE cluster for organizational purposes.
+
+- The [Images collection](/api/v4/images-image-id) now contains the `updated` property. This property returns the date that the current Image was last updated.
+
 ### Changed
-### Fixed
+
+- The [StackScript collection's](/api/v4/linode-stackscripts-stackscript-id) `deployments_total` property is now filterable. See [Filtering and Sorting](/api/v4/#filtering-and-sorting) to learn how to search API v4 collections.
+
+### Fixed
+
+- Validation has been included to prevent users from adding a credit card expiration year greater than 25 years from the current year. A user will now receive an `Expiry too far in the future` error message when this occurs. This bug fix affects the [POST /account/credit-card](/api/v4/account-credit-card/#post) `expiry_year` property.
