On September 23, Arbitrum Developers posted on X that the new Arbitrum Nitro v3.2.0 is now available and can be found at offchainlabs/nitronode: v3.2.0-f847be0. This version will include stability fixes and other changes, and does not include any configuration changes for v3.1.2. If users run nodes on Arbitrum One, Nova, or Sepolia, they need to upgrade to Nitro v3.2.0 to avoid downtime. This upgrade is mandatory and should be performed immediately. Please try to upgrade to this version within 48 hours (as of 10:00 on September 24) to avoid node downtime. For RaaS providers, if you are running a chain on ArbOS 31, please upgrade to Nitro v3.2.0 and ArbOS 32 immediately.
