ChainCatcher message, Starknet tweeted that its mainnet will upgrade to version v0.13.3 on November 27. At that time, the Blob Gas price on Starknet will be 5 times cheaper. Some node operators running Juno instances need to upgrade to version v0.12.4 to synchronize with v0.13.3 blocks. If using Pathfinder > v0.14.2, no action is required.
