Introduction

The upcoming upgrade disables modexp, the upgrade is already deployed on cardona testnet (so partners should also upgrade to these versions) and although the v4.0.4 version of zkProver is compatible it is highly recommended to upgrade and use these versions. There is no change in the configuration

<aside> ⚠️ Note that the node versions v0.5.7/v0.5.6/0.5.5 with Prover v4.0.4 are required to be able to upgrade 0.5.8 Although, it is highly recommended to update to v0.5.8 with prover v4.0.8

</aside>

<aside> ⚠️ Note that the version v0.4.6 with Prover v0.3.3 and earlier would be obsolete.
