TechFlow news, on September 23, the Arbitrum development team announced the release of Arbitrum Nitro v3.2.0. This version is available at offchainlabs/nitro-node:v3.2.0-f847be0 and primarily includes stability fixes and other optimizations, but does not involve configuration changes from v3.1.2.
Arbitrum emphasized that users operating nodes on the Arbitrum One, Nova, or Sepolia networks must immediately upgrade to Nitro v3.2.0 to avoid node downtime. This upgrade is mandatory, and the development team requires node operators to complete the update within 48 hours (by 02:00 UTC on September 24) to ensure continuous node operation.
For RaaS (Rollup as a Service) providers running chains on ArbOS 31, an immediate upgrade to Nitro v3.2.0 and ArbOS 32 is required.
