+==================
+
+Nimbus `v22.5.0` is a `low-urgency` maintenance release. It implements the proposer boosting fork-choice policy and is compliant with the latest [Bellatrix specifications](https://github.com/ethereum/consensus-specs#bellatrix-also-known-as-the-merge). It also provides an early preview of our built-in support for [BLS threshold signatures](https://notes.ethereum.org/@djrtwo/blst-rfp) (via regular Web3Signer instances): this marks the first step of our long-term [secret-shared validators roadmap](https://github.com/status-im/nimbus-eth2/issues/3416) which enables node operators / staking pools to deploy Nimbus in secure high availability setups (guaranteeing ~100% uptime).
