Cairo Toolchain Update v2.19.5 Released by Starkware

Cairo, the programming language and compiler toolchain developed by Starkware, has received an update to version v2.19.5. This release is a maintenance update that includes fixes for code generation and Cairo semantics.

The update was published on September 17 through the official starkware-libs/cairo repository. It's essential to note that this is not a Starknet hard fork, but rather a developer-tooling update.

The compiler fixes in v2.19.5 aim to resolve bugs in code generation, semantics, and intermediate representations, which can have far-reaching consequences for developers working within the Starknet ecosystem.
