Release 22.4.2 — December 2022

Feature	Description
Ethereum support for atomic transactions (two-phase commit)	You can now run Ethereum transactions as part of an atomic transaction workflow by using the `atomicTransactions` REST API, where the combined transactions are either all committed or all rolled back. See: Make Atomic Updates Across Chaincodes and Channels, Ethereum Interoperability, and Atomic Transactions REST Endpoints
Support web3-based interactions with Ethereum smart contracts via the proxy	You can use the `web3` library and the `fab3` proxy to deploy and interact with smart contracts on Ethereum Virtual Machine (EVM) chaincode that is deployed on Oracle Blockchain Platform peer nodes. See: Configuring the Fab3 Proxy
Upgrade of instances running Hyperledger Fabric v2.2.4	You can now upgrade the version of Oracle Blockchain Platform that is running on instances that are based on Hyperledger Fabric v2.2.4. See: Upgrade an Instance
Rich queries in the console UI	You can run and analyze rich queries on the state database for a specified chaincode and channel in the console's Channels tab by using the More Actions menu. See: Rich Queries in the Console
Chaincode package deletion	To free up disk space, you can delete obsolete or unused chaincode packages by using the REST API or the console UI. See: Delete a Chaincode and Delete Installed Chaincode Package
OAuth 2.0 support for REST proxy event callbacks	In addition to mutual TLS, REST proxy event subscription callbacks now support invoking callback endpoints that are secured with OAuth 2.0 authorization. See: Subscribe to an Event

Release 22.3.2 — August 2022

Feature	Description
Atomic transactions (two-phase commit)	You can now use the REST API to combine a group of transactions across multiple channels into a single (atomic) transaction. Atomic transactions use the two-phase commit protocol, so that the combined transactions are either all committed or all rolled back. You can use this function to work around Hyperledger Fabric limitations related to atomic cross-channel updates. See: Use Atomic Transactions and Atomic Transactions REST Endpoints
Oracle Blockchain Platform support for global distributed transactions	Oracle Blockchain Platform now supports the X/Open group XA (eXtended Architecture) standard, which specifies the interface between a global transaction manager and local transactional resource managers. The XA standard is based on a two-phase commit protocol. Oracle Blockchain Platform now provides a Java library that can be used as an XA resource manager, allowing global transaction managers to coordinate and sequence a series of atomic operations that can include Oracle Blockchain Platform blockchain transactions alongside databases, queueing systems, and other XA-capable resources. See: Use the XA Java Library

To learn more about the impact of a new version of Hyperledger Fabric on existing applications, see Updating Applications for a New Platform Version.
Reliable callbacks for event subscriptions	Oracle Blockchain Platform now supports more reliable delivery for subscribed events. If a callback fails, it is retried based on an exponential backoff policy. When you subscribe to chaincode events, you can specify the maximum number of times that a callback will be retried after a communication failure. See: Subscribe to an Event in the REST API documentation.
