Starknet v0.14.4 Mainnet Upgrade
Starknet (STRK) · Releases & Updates · October 6, 2026
Starknet v0.14.4 upgrade went live on Mainnet on October 6, 2026, after the September 15 testnet release.
Starknet, the Ethereum Layer 2 validity rollup built by StarkWare, upgraded Mainnet to version v0.14.4 on October 6, 2026; Testnet had moved to v0.14.4 on September 15. The release is small and mostly transparent for users. Its main new capability is proving block-sized transactions through the SNIP-36 client-side proving flow, up to 1.1B L2 gas per proven transaction, to be enabled once audits are complete. It also realigns OS gas pricing weights (under 1% effect on most transactions per StarkWare), removes long-deprecated feeder gateway endpoints and moves the block committer into the Apollo sequencer. Breaking change: proofs generated with the 0.14.3 prover are rejected after the upgrade.
