According to ChainCatcher, Starknet announced that its mainnet will be upgraded to version v0.13.3 on November 27. By then, the Blob Gas price on Starknet will be reduced by 5 times.
Node operators running some Juno instances will need to upgrade to v0.12.4 to sync with the v0.13.3 blocks. If using Pathfinder > v0.14.2, no action is required.
