+# Introducing Clio version 2.2.0
+
+Version 2.2.0 of Clio, an XRP Ledger API server optimized for HTTP and WebSocket API calls, is now available. This release adds new features and bug fixes.
+
+## Notable New Features
+* Price Oracle support, including `get_aggregate_price` API
+* Forwarding to rippled for `feature` API
+  * Clio-native implementation of `feature` API is planned for future implementation
+* Improved doxygen documentation
+* TLS 1.3 support
+* C++23 compilers
+
+## Amendment Support
+The following amendments have been introduced since Clio 2.1.2 and have transaction model changes.  Clio 2.2.0 is built with `libxrpl` 2.2.0, which supports these amendments.
+
+* [PriceOracle](https://xrpl.org/known-amendments.html#priceoracle)
+
+If these amendments are enabled and you have not upgraded Clio to 2.2.0 or newer, the ETL will be amendment blocked and new ledgers will not be processed.
+
+To check the current voting status of these amendments on Mainnet, see the [XRPL Amendments Dashboard](https://livenet.xrpl.org/amendments).
