Conflux (CFX) said v3.1.1 fixes node panics, memory issues, a trace-query deadlock and RPC errors, and updates OpenSSL in Linux builds.
Conflux (CFX) has announced a v3.1.1 node upgrade aimed at fixing several stability and security-related issues, including possible node panics, excessive memory usage and RPC errors, according to the project’s October 22, 2026 forum post.
In the announcement published on October 22, 2026, Conflux said the release addresses a security fix for several possible node panics and excessive memory usage, plus bug fixes for a possible execution deadlock during concurrent trace queries, incorrect peer reputation updates during simultaneous connections, and missing block-body checks during catch-up synchronization. The post also says v3.1.1 corrects eth_createAccessList returning empty or incorrect access lists and fixes a panic when tracing the genesis block.
The project said Linux builds in v3.1.1 upgrade OpenSSL to 3.5.9 and update dependencies to address security issues. Conflux instructed operators with running nodes to suspend the node, replace the executable named “conflux” in the run directory with the v3.1.1 executable, and restart the node. For new deployments, the post says users can download and run the latest v3.1.1 release.
The announcement did not specify an impact assessment beyond saying the upgrade is recommended and that it fixes issues that could potentially cause node crashes and excessive memory usage. No deadline, network-wide enforcement date or refusal penalty was provided in the material supplied.
60% over 24 hours, with a market capitalization of $278,866,528, according to the supplied market data for October 22, 2026.
