StarkWare ships Cairo v2.19.5, a compiler patch rather than a Starknet hard fork
- —Cairo v2.19.5 was published on September 17, commit 3a267a8
- —The patch covers Sierra code generation and Cairo semantics fixes
- —The full changelog was not disclosed, so impact needs verification
- —The release does not alter Starknet consensus or transaction handling
Why it matters: For STRK holders this is a technical patch with no price impact; developers should check compatibility with Scarb and Starknet Foundry.
