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