Five new amendments are now open for voting according to the XRP Ledger's amendment process, which enables protocol changes following two weeks of >80% support from trusted validators.
If you operate an XRP Ledger server, upgrade to version 2.2.0 by June 17, 2024 to ensure service continuity. The exact time that protocol changes take effect depends on the voting decisions of the decentralized network.
If you operate a Clio server, Clio needs to be updated to 2.1.2 before updating to rippled 2.2.0. Clio will be blocked if it is not updated.

Amendments and New Features
(These are changes which may impact or be useful to end users. For example, you may be able to update your code/workflow to take advantage of these changes.)
featurePriceOracle amendment: Implements a price oracle as defined in the XLS-47 spec. A Price Oracle is used to bring real-world data, such as market prices, onto the blockchain, enabling dApps to access and utilize information that resides outside the blockchain. #4789
