🚨‼️ DO NOT BUILD FROM SOURCE ‼️🚨
📦 BINARY PACKAGE ONLY: TAGGED AS v8.6.0-pre.1 📦
This is a mandatory security release for all validators and full-node operators. It is distributed as prebuilt, verified binaries only as part of a coordinated security response. Source code and full technical details will be published after an internal coordination window closes.
This is a consensus-breaking upgrade recommended for the entire validator set. It delivers security hardening across the chain's state-processing layer, including the embedded Cosmos components, along with associated dependency and module maintenance.
Aspart of a coordinated security response, the binaries for this release are distributed in prebuilt, signed form and the source is being withheld until the public disclosure window closes. Operators should upgrade using only the official signed binaries and must not build from source. The fix is complete, verified, and has no known regressions; the objective of this proposal is simply to move the network to the patched version at a single agreed height.
