| 15 | + |
| 16 | +We are pleased to present Magento Commerce 2.2.3. This release includes 35 enhancements to product security, a change to the Magento Admin to support recent USPS shipping changes, and a copyright update. And thanks to our community members, it also includes support for Elasticsearch 5.x and enhancements to ACL control for cache management through Magento Admin. |

| 19 | +## Highlights |
| 20 | + |
| 21 | +Look for the following highlights in this release: |
| 22 | + |
| 23 | +* **Enhancements that help close cross-site request forgery (CSRF), unauthorized data leaks, and authenticated Admin user remote code execution vulnerabilities**. See [Magento Security Center](https://magento.com/security/patches/magento-223-2112-and-2018-security-update) for more information. |
| 24 | + |
| 25 | +<!--- MAGETWO-84775 -->* **Support for Elasticsearch 5.x**. See [Install and configure Elasticsearch](http://devdocs.magento.com/guides/v2.2/config-guide/elasticsearch/es-overview.html) for more information about using Elasticsearch with Magento. *Fix submitted by community member <a href="https://github.com/afoucret" target="_blank">Aurélien Foucret</a> in pull request <a href="https://github.com/magento/magento2/pull/822" target="_blank">822</a>.* |
| 26 | + |
| 27 | +* **Change to Magento Admin to support recent USPS shipping changes**. On February 23, 2018, USPS removed APIs that support the creation of shipping labels without postage. In response, we’ve removed this functionality from the Magento Admin. Consequently, you cannot create and print shipping labels that do not have postage applied. If you require USPS postage printing capabilities, please visit [Magento Shipping](https://magento.com/products/shipping) to learn more, and explore various shipping extensions on Magento Marketplace. |
| 28 | + |
| 29 | +* **New layers of control for cache management tasks managed through the Magento Admin**. This release introduces finer permissions for cache management tasks such as flushing cache storage, flushing the Magento cache, and refreshing cache types. *Fix submitted by community member <a href="https://github.com/bartoszherba" target="_blank">Bartosz Herba</a> in pull request <a href="https://github.com/magento/magento2/pull/78" target="_blank">78</a>.* |
| 30 | + |
| 31 | +* **Updated copyright to 2018**. |
| 32 | + |
| 33 | +## Security enhancements |
| 34 | + |
| 35 | +Magento 2.2.3 includes multiple security enhancements. Although this release includes these enhancements, no confirmed attacks related to these issues have occurred to date. However, certain vulnerabilities can potentially be exploited to access customer information or take over administrator sessions, so we recommend that you upgrade your Magento software to the latest version as soon as possible. |
