Neo X has released v0.5.3, a patch update for the EVM-compatible blockchain that introduces several incremental improvements and bug fixes. The team said the upgrade is “highly recommended” for node operators currently using v0.5.2.
The release, called “Quenchation,” continues Neo X’s convention of assigning distinctive names to version updates. It follows the March 6 ‘Polarization’ release, which introduced broader infrastructure changes related to newer Ethereum client behavior, added blob data storage at the execution layer and APIs for EIP-4844, and migrated the network’s peer-to-peer communication model to support post-merge behavior.
Neo X v0.5.3 is a narrower maintenance release focused on stability and cleanup. According to the release notes, the update refreshes seal proposals when ChangeView occurs, updates the error message shown when etherbase is missing, and reduces the log level for missing blob transactions.
The patch also includes two bug fixes: excluding transaction blob sidecars in the OnTransaction callback and correcting blob error handling for blocks committed by the dBFT consensus protocol. Both address edge cases in the blob-related functionality introduced in the previous release.
The release notes outline a simple upgrade path for node operators moving from v0.5.2: download the new binary, gracefully stop the node, replace the old binary, and restart the node. Unlike the previous upgrade, v0.5.3 does not require any additional configuration changes.
